[Q] Windows "USB Device Not Recognized" error

Does anyone else have this problem? When I connect my phone to either my laptop (winXP) or my desktop (win7x64) I periodically - constantly, really - get this message:
"One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message."
When I click the message, it identifies my phone as a Generic USB Hub (4 ports) with the first child being a USB Mass Storage Device, the second being the problematic "Unknown Device" and the last two are "Unused Port"s.
This happens whether the phone is in charge-only or mass storage mode. I tried installing the autoplay drivers and that didn't help, so I uninstalled them. No hubs are involved - I've always plugged straight into the tower or laptop. I've also tried two different quality (first party Motorola) cables.
Mass storage mode works fine despite the error - I can access the Internal storage as well as the SD card. Is this a problem with my phone, or am I missing some software on the Windows side?

Have you tried installing the WHQL drivers for this device from here: http://www.lgforum.com/resources ?

Thanks for the suggestion major. I tried those drivers with no luck - the message still pops up frequently in both charge and mass storage modes.

Odd... I had issues with the original drivers, but once installed, I never had another prompt again.
edit: I had it one more time, but it found them and installed them

that's very interesting. i also use 2 machines--one with xp and one with win7. my usb connection worked flawlessly on both. fyi...my connection default is mass storage, and i've actually never tried the other options. i wonder why the difference? did you make any changes? are you rooted? i am not.

Hi gr33nT,
Thanks for responding. I'm 100% stock at the moment, not rooted or anything (though it will be soon ) Sometimes I use charge only if I have it connected to my laptop at work but I still want to listen to music from the SD card. I may see if I can get Verizon to swap out the phone, the message pops up all the time and it's getting annoying...

A quick follow-up on this one: I tried the stock LG cable on my win7 machine (I had been using moto cables). I installed BOTH the bootstrap drivers as well as the LG drivers from the web - still happening. I rooted with these drivers via S1C so I know the drivers are good. If nobody else has run into this, something is probably wonky with my phone, so I'm probably going to exchange it.

For mine, every time I connect, it asks me if I want to install bootstrap. Even though, they have already been installed cuz I am rooted.

I've had the same issue both as stock, and rooted and in every configuration with the phone and PC you can think of. I've downloaded the drivers and installed them from both the phone and web site all to no avail. This is really getting annoying.
I hope someone has a fix for this.

Hmm...that is troubling. I'm still having the issue running the stock rom and rooted, now. When I get time I'm going to drop by the Verizon store and hopefully they'll replace the phone - I suggest you try the same, as I doubt it's the computers we're using. My win7 box and winXP work laptop could hardly be more different!

I doubt a replacement will fix anything, I experience the same thing as majorpay. Drivers worked for a while and then it started asking for it again. This also causes issues when using usb tether as its connecting and disconnecting. The issue is not present when used as a mass storage device.

Hi bwhxeon,
The issue (USB device not recognized - it sounds like you're referring to the autoplay driver installation) happens for me in mass storage mode also. I believe it has to be the phone as I've never had this problem on any of my PCs with my OG Droid or any other USB device. With this phone, I have the problem on all of my PCs.

I had the same problem. The error popups seemed random at first. I noticed if I enabled/disabled the WIFI on the device while it was connected, I could make the error popup.
I ended up getting a new replacement device when I also noticed the 4G Hotspot wasn't working either even after a factory restore. There was definitely a hardware issue with the phone.

USB Unknown Device
same issue here.. when using ADB though I have to set to Internet Connection then it goes away for a while until I want mass storage or just charge from USB again, then re-appears.

LG is not like most other phones as in usb debugging only works in internet connection mode where others go into it as soon as you plug it in.

Just kind of scanned this thread but have you tried a different USB cable? I was having a problem with mine only wanting to charge with the stock so I grabbed another cable and it has worked right ever since

Same issue, two different pcs, with two different cables. Bootstrap does not load anymore so I am using the drivers from the links, both sets of Lg verizon drivers

WP8 is not detected by my computer - does not appear in windows explorer

My HTC 8x for T-Mobile doesn't show up in windows explorer. It suddenly stopped after working perfectly from the day I got it. I thought it may be my computer, like a missing driver or a setting but it doesn't work on my work computer, while my friends lumia works perfectly on the same computer.
Did there a setting I switched off in the phone?
I really don't want to hard reset cause I have so many email accounts set up with the phone. Any help would be great!

http://www.windowsphone.com/en-us/how-to/wp8/windows-phone-app-for-desktop
or try to delete driver and reconect phone.

didn't do anything. Plus it doesn't work on another computer that detects my friends lumia.

Anyone have any ideas? Please any help?

I had this problem on my computer that was previously connected to my Lumia920, and the second time I have connected it, nothing detected. I just plugged/unplugged the device several times, and after 5-6 times, there it was. Is ur device functioning properly? Is there any sound of connection from ur computer when u connect ur device?

Is your phone locked, by chance? I noticed that if the phone is locked it will not expose the file subsystems unless its unlocked.

some people have also reported that using a different usb port in your computer also helps.

Make sure you are using short USB cable that is working with another phone. Half of problems i have with computer "not detected" phones was due to low quality USB cables and under-powered USB ports, especially ones located at front of computer. Try to experiment with different USB cables and USB ports on different computers, this sounds stupid but helps in half a cases .

I have some problems with my Lumia 920 when the cord is to long!
Try to use the orginal cord!
Hope it helps

Watch for Memory card!
Hi,
Try to remove the memory card and reattach the device.
It solved the problem for me and read on some places about it.
Be careful what size and 'shape'(brand) memory card you use as it can block usb usage as it seems for me.

Method 1:
Disconnect all the external devices (printers, scanner, USB (Universal Serial Bus) drives, etc...)Except mouse and the keyboard and then boot up.
If this corrects the issue then add the devices back one at a time until you discover the piece of hardware causing the issue. Then get any updated drivers\software for the device.
Method 2:
If you still come across the issue, I suggest you to run Hardware Troubleshooter and then check for the issue.
Method 3:
If the above step does not help us to diagnose the issue, uninstall the drivers for USB [Universal Serial bus] host controller and restart the computer. Let Windows install the generic drivers and then see if it helps you to fix the issue.
a) Open Device Manager by clicking the Start button, then Device Manager in the search box.*
b) If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
c) Look for the device under USB [Universal Serial bus] host controller, right click on it and select Uninstall.
d) Reboot the computer.
e) On reboot, Windows 7 should re-install the drivers automatically.
You may also refer the steps from the manufacture website or contact Nokia for any known issues.

Try installing the Nokia Software Recovery Tool or the Nokia Care Suite. It should install all of the drivers necessary to connect your device. There is probably a driver corrupted.
the question you need to ask is if your friend has the same model Lumia as you. If he doesn't, it could be a problem with the driver on your PC.
If he does have the same model as you, it has to be a problem with your phone. You need to do a factory reset.
Have you checked if it works with the Windows Phone app?
Also, there is really no reason to have a need to connect it to a PC. As long as you store your documents and photos in OneDrive, you can easily access them from your PC without having to connect your device.

Note 3 won't connect to PC, Kies 3 installed and everything

So I've run into a weird issue that was happening with my Atrix HD the last few days of its life too and now over to the note on my laptop.
I know this is probably a more computer specific problem, as it's recognized on my desktop but I'm running outta ideas here so maybe someone can help?
I've been flashing and rooting and all that jazz since android was released so I know how to work it and my thinkpad was accepting mtp/android connections as recently as september. I unlocked my Atrix HD bootloader and all that but couldn't get the phone to accept the twrp so eventually I just gave up because it was just a stop gap phone.
But now with my new Note 3, I can plug the phone to the laptop and it'll charge but it doesn't bring up the MTP notification (all my androids do this now)
I've checked device manager, it's not even an unknown device in the list..so weird.
Anyone run into this issue before? I know it's not really phone specific but yeah.
thanks in advance

Are you using it on a USB 3.0 port? My home pc only recognizes mine if it's plugged into USB 2.0. Fought this same fight last night myself. Good luck.

Do you guys have BC 1.1 enabled on your machines? If so that's why the 3.0 port doesn't work.
Sent from my SAMSUNG-SM-N900A using Tapatalk 5

to both of you, my thinkpad (for some awful reason) doesn't have usb 3.0, so no there isn't any USB 3.0 issues.
Literally plug it into my laptop, and nothing. no response from the computer at all not even in device manager, just starts charging as if the phone was plugged into a low voltage socket or something.
baffling.
works absolutely fine on my desktop, but I don't have all my adb and sdk tools set up the way I like them on there.
I have no idea.
ERR edit that it just started working :/ weirdd

Verizon note 3 here - same issue.

Do you guys have any programs that's suppose to charge devices faster with usb? It has to be software related on your laptop

To everyone with this problem, you have to specifically download the Note 3 drivers from Samsung
samsung.com/us/support/owners/product/SM-N900VZWEVZW
I was having the same problem, but now both Kies and manual usb file transfer work perfectly on Windows 8

I have same problem here as well ?? its not reconizing my phone in usb 3.0 and i have the newest drives as well for note 3 gn 9005

got it working
Had the same problem after trading in handset,maybe there is some kind of hardware identifier messing things up for usb?
I removed (uninstalled and deleted) drivers for usb, including for hub then reinstall hub drivers followed by reinstall driver option in Kies3 to install samsung drivers. This got everything working.

Your going to mess your phone up some kind of bad playing with those settings if you don't know what your doing. Also please don't recommend doing any of that without a trustworthy source because you can cause another person to mess up their phone as well.
The Note 3 does NOT support BC 1.1. That's what "Fast Charge" or whatever they call it is. Your phone will not use that connection so there is no workaround, just disable the BC 1.1 function.

Yes I stand corrected however I always mess with these settings in order to unlock 90% of the gsm galaxy lineup. This is just a different way of mounting your phone to the computer at least that is what I was told and have been doing for a while. I have tried all the methods on the note 3 and so far no problem. I have been using my phone like this for a while without any hiccups and I had this usb problem since day one on my SAMSUNG laptop so I tried this method which worked. You can easily switch back to the same setting but once again you might be right about the messing up your phone part. FYI MTP just stands for media trasnfer protocal I think so I went with it after a little research.
Just letting everyone know what worked for me no harm done

I tried installing the drivers from samsung with no luck and then tried this and no luck either. GOD DAMNIT! Why is google making it harder and harder to do this ****? Why can't it be as simple as moving files to another other usb drive like it used to be.

IT works!!it actually works..
what i did was,,download kies 3,supported kies for note 3, and go to Tools tab, and see the option "reinstall device driver" dont unplug your note 3,,and voila!!just wait a while, and see how the kies recognize ur note 3..:laugh:

Android3220 method works for me using Note 3, Windows and Kies. Thank ypu.

Do you plug it in USB port 3.0 or in 2.0? Mine, either port are not working

Try using a USB hub,,, 2.0 or 3.0.... this will work......

Go to device manager then to USB find the Samsung driver uninstall. Plug your note 3 in then your system will see your note 3 and reinstall your drivers. Then your good to go.

Cannot get watch to connect to pc

I have installed all drivers i could fine. Whenever i plug the watch into my pc it doesn't even make the chime sound, nor does the device show up in device manager.
Can someone please help me, i just got my watch two days ago and would like to enable more cores because mines quite laggy on android wear 2.0.

If you have enabeld USB Debugging ?
This you can do in the Developers Options.
If you dont see Developers Options under SETTINGs then you must first enable the Developer Options...
To do this ...
Go to SETTINGS there in Devices Info and then TAP 7 times at Buildnumber... after this go back to Settings and you see the Developers Options and there you can enable USB Debugging
Sorry for my bad english...

i have already done that also. ive tried about everything i can fine. the dock charges the watch just fine, i have also tried different usb cords. is there any way to adb over wifi?

Hey did you found any solution?
I am on the same boat, the watch can charge and works (laggy) fine, but I am unable to let it be recognize in any way.
I tried same USB cord with several phones and it's ok, but the watch cannot be in any way recognized...

Someone please help us out lmao, the watch is so damn laggy and battery is awful.

I managed to do adb over wifi on the watch, but obivously this do not help with unlocking bootloader or anything in fastboot mode..

Did you all download and try the latest adb? I was having this same issue and turned out that once I updated the adb from the Android sdk, everything worked perfectly.

Uhm, I'll try thank you!
I downloaded all the driver I could get, even from official android.com site, but still the issue is same:
When I plug USB cable in the PC, I get no chime sound or request of anything: tried putting the watch on cradle in standard running mode, in fastboot mode, or in recovery or even powered off.
Same result: no reaction from PC at all.
Tried connecting various phones with same cable as the watch cradle usb cable, everytime the driver kick-in and phone is detected and system either use Google USB driver or ask for drivers.
I read somewhere on the internet that if phone is not connected with Wear app the smartwatch is not connected? But how to do that if the watch is in fastboot mode for unlocking?

Btw I also found that the system update was to version NXG47C and now the fastboot menù is indicating that bootloader is version LENOK22b (secure boot is enabled in green and lock state is locked).
I am lost, even the SDK Android drivers did not change a thing, but more than anything else I do not get why PC do nothing (not even chime sound) when plugging in, my cradle is original and all things come from its box from 2014..I never tried before connection so I do not know if that was working before, but I am starting to think I need a new cradle maybe...

I have 2 cradles (that -same thing as you- work with anything else instantly) and since the NXG47C/LENOK22b combo simply do not work, so it seems it isn't a cradle problem. :crying:

Sadly, no.
I was just looking to cradle options but what you are reporting here now makes me believing that really, it's something else...but probably only LG knows why they did that...Only reason I can think of, is to make us users purchase newer models locking out features that make it still good with AW 2.0
It's really a pity.
My only other idea is to try with a different OS, as atm I got only Win 10 64bit Creator Update , but I could use a old HDD and try with a Win 7 32bit...but it's a LOOOOOOOOONG shot as from my experience at least the chime sound should be there...:crying:

Oh! Different OS - I forgot to mention it before, sorry: I tried on Windows 10 and MacOS.
Again, both work fine with other Android USB-debugging-active devices.
Sorry for adding more bad news to an already bad story.. :/

I would have guessed this, sadly.
Well, this means something needs to be found to reactivate the fastboot connection from the devs...meanwhile, I found that the old dev options to lower the scale of the animations improves a bit the slugginess of the watch...
Let's hope someone notices this thread and find a way to help us out, as I'm 100% no-dev...

Exactly same thing about me. USB plugged in and nothing happen, I tried win 10 OS and win7 - same problem - I also thought it is cradle problem, I almost bought a new one but after you wrote I dont't think I could help look we are stucked with AW2.0 and only thing is hope someone will find solution for this...

I am still stuck on this situation, no way to make watch try the USB connection.
Could it be possible that the latest update disabled the USB ADB?
Can someone confirm if the USB ADB files are still in the package?
And if not, is it possible to add them back using for example ADB over wifi, through maybe the original recovery if not possible with system running?

It is really anointing when some other users write about downgrade without problems. I'm thinking how is it possible, so everyone got the same version of AW2.0, it is really weird

I have 2.0 on gwr and my win 8 recognised them. I just installed adb usb drivers in same way as I did for Huatch: as Motorola android sooner composite adb interface.

Probably installed with drivers for motorola phone. The thing is I did not install this exact adb driver on purpose. I found it as I was trying out anything to make the watch connect to PC. It was a pure luck.

same thing happen to me!
I thought it was the cradle, I have 3 cradles, though all is not original, all fail. so I though the cradle only can charge. But I vaguely remember I once using it to flash, but my memory is not so reliable, so it can be the original or the 'not original'.
I can connect ADB using the bluetooth debug mode and go to fastboot, but even in fastboot mode, my pc still cannot detect the watch.

Massive Storage not working in T813, computer does not detect

Hello fellas,
I have a problem with my brand new T813 running the latest official firmware available (Android 7).
Massive storage is not working, my computer running Windows 10 with updated samsung drivers has failed to detect it. The device charges, but I am unable to modify the usb options, regardless the choice MTP always remain.
I have tried with three different cables, all of them work fine with my S7, the computer never detects the device, eventhough it's charging. This means it is not a problem with the device's micro usb port. I have the latest drivers, and I have also tried with all usb ports. None of them seemed to do the trick.
The computer has faulty usb 3 drivers, ever since I have installed Windows 10, the speed is not what used to be with the previous configuration. I have the same drivers, I don't understand what's wrong.
Any help would be appreciated, I have tried most solutions mentioned on this community and they didn't work. I can't flash the device because it is never detected. The problem still persists after a restablishment via the menu.
Download mode shows
QUALCOMM SECURE BOOT: ENABLE (CSB)
FRP LOCK IS OFF
[UPDATE] 06/08 11 AM
Left the device at SAMSUNG ARGENTINA repair shop. Also had to pay 300 pesos (around 20 dollars) as a diagnostic fee, they told me that if I accept the repair cost later on, they would discount the 300 pesos I have paid out of the total price. And if I don't, they will keep the money.
Will update again when Samsung calls me in a couple of days. Maybe this monday, I hope so.
[UPDATE] 06/08 15 PM
I have just received an email from BGH, which is the SAMSUNG ARGENTINA official partner for repairs. They told me that the problem is a FAILURE on the SUB board.
http://www.ebay.com/itm/Micro-USB-C...g-Galaxy-Tab-S2-9-7-034-SM-T813-/322414846816
The good thing, is not that expensive. The bad thing, this tablet hasn't arrived officially to Argentina, and since it has been bough in Chile, the guys at SAMSUNG ARGENTINA had to request an international order replacement, which I have been told it could take some time. But they will eventually get the piece.
Will update again.

What does device manager report when the device is connected?

Sure you don't have ADB enabled? Disable developer settings and try again.

Thanks for replying, please refer to first screenshot. No Mass Storage option appears after connecting device. MTP option seems to be forced, i am unable to change it.
The tablet is brand new, but the guy who sold it to me said that it has always been working. He even told me that it has been barely used, and that the device is recognized when connected to an usb audio system. It has been upgraded to 7.0.1 a couple of days ago, maybe that's the problem.
I have just tried with a macbook air and it didn't detect it either, it is only charging. The same computer has detected my S7.

Modern devices don't use mass storage anymore, they use the MTP protocol.

Sure you don't have ADB enabled? Disable developer settings and try again.

Thanks for replying. ADB and USB debugging activated, I have also performed a factory reset and the problem still persists.
Using a microSD didn't help either.

There is no notification when I plug in the cable, that is the problem.

Sadly nothing at all, the device only charges via usb. This is very confusing because the guy who sold it to me said it was working, but he has also said that he has never plugged it in a computer.

There are no error codes in device manager when the device is plugged in?

Nothing, not even an unknown device. I'm lost here.

I have tried with a mac and nothing has happened, it is only charging. The same computer has detected my s7.
A lot of people seem to have experienced this problem, the remaining solutions I didn't try are using other pc or try cleaning the female port with isopropilic alcohol. Hope it does the trick, otherwise I'm screwed.
I will try at work tomorrow.

Modern devices don't use mass storage anymore, they use the MTP protocol.

That is the problem, when I connect the cable nothing happens, it is only charging. Windows doesn't even detects it as an unknown device and neither does mac osx.
I didn't know mass storage is not used anymore, I think my S7 does have it and it works. I will try at work tomorrow.

When the problem appears with different USB cables and in different computers, as in your case, you have to look into the possibility that it may be a hardware issue.
I hope I'm wrong about this, but it sounds like the DATA+ or DATA- pin is damaged in your micro usb socket (pins 2 and 3, see http://pinouts.ru/PortableDevices/micro_usb_pinout.shtml)

Yes, I'm afraid it could be a hardware problem. But that would also mean the guy who sold it to me is lying. I have to say it, the device looks like it has been treated with care. However, i have noticed the plastic has worn out a little near the usb port, those black marks could indicate not so much care when plugging or unplugging the cable.
I hope we are both wrong about this. Tomorrow i will know. Fixing this is a pain in the ass, right?

¡Che! Replacing the microusb receptacle would not only be a pain the ass, but if you make a tiny mistake while soldering or desoldering you can end up with a bricked tablet.
Anyway, let me know what you find out tomorrow, good luck boludo.

Actually not too bad as the Micro USB port is a module and can simply be swapped out.
