[Q] All of sudden SGS not recognized via USB?

Hi Guys:
I have a SGS from Bell Canada, installed Kies on my PC home computer. Was having the familiar problem of connecting the phone to the pc, but finally solved the problem, thanks to tips from this forum.
I recently upgraded to JH2 via Kies. I also have connected numerous times using mass storage option to transfer large media files.
Everything was working fine until I tried to connect to pc today (as mass storage), and got a message from computer saying "USB device not recognized". I tried to connect via Kies but no luck either.
I thought it was a problem with the USB driver. Tried uninstalling and reinstalling "Samung_USB_DRIVER_For_Mobile_Phones_x86, v 1.3.450.0", still couldn't be recognized.
The phone itself doesn't seem to know that it's connected to the pc either. It doesn't do anything, just sits there. And there's no option to unmount the internal drive from the drop down menu.
Any suggestions would be greatly appreciated!

that is exactly 100% what i had 2 days ago

for some unknown reason, it works perfectly fine without me doing anything different now.
it's like a lady's menstrual thing, comes and goes without any warning

Are you using a third party launcher?
If so try switching back to TW first.

[Q] Captivate USB charges but no data connection - flashing stock w/o ODIN

Just a quick question- I have a Captivate that will charge when plugged in via USB but there is no data connection. The phone doesnt recognize that its plugged in to a computer, and therefore despite being able to boot into download and recovery mode, I cannot use ODIN to do anything. Clockwork wont work either due being on 2.2.
Ive read some other threads where most concluded it is more or less a hardware failure. Im coming to that conclusion myself, but wanted to check with you guys first. The audio jack did the same thing for a couple days-- it wouldn't work when plugged in. It did come back on its own, though Im not sure why.
Im running Cognition 2.2beta3, and cannot flash back to a stock rom nor to any other rom due to the lack of being able to use ODIN.
Is there any other way to flash back without ODIN? Also, if this is indeed a hardware failure- how can I go about getting it fixed? I traded for it on craigslist for an iPhone 4 so I didnt get it direct from AT&T. It did work for the first couple months.
Thanks in advance for your help!

Do you have USB debugging enabled (Settings-Applications-Development)?
If so, you won't get the connection choice screen when you plug in your USB. You can either disconnect USB debugging to get the choice screen, or leave USB debugging enabled and click on the "Select to copy files" choice in notifications.

I have tried with USB debugging on and off, and in various USB modes. None work, as the Captivate doesnt even acknowledge theres a data connection that has been made.
It worked in the past in all modes... debugging with the option to mount the drive, mass storage, Kies, and the media mode. No dice at the moment. Tried a hard reset today... nothing.
Looks like it could be a hardware issue-- just weird as the audio jack had the same issue and seemed to (randomly) resolve itself. Thanks for the suggestion! Any other ideas?

I had the exact same issue as you few days ago. One forum member recommended to me to uninstall the Samsung USB driver and reinstalling it again. It worked as soon as I did this. You should give it a try.

I had a similar issue when performing a master clear and flashing JI6. I am on windows 7, and I noticed that a different driver is needed to use Odin in download mode. I had been sideloading apps as well as transferring files with the stock driver from samsung, but my computer still wouldnt recognize the phone when in download mode. The solution was quite simple, when entering download mode my computer gave me the "driver not found" messege. I just let Windows Update find the right one for me (not sure if its generic or not) and everything worked fine after that. Hope this was relevant to your issue.

And I guess you can't do the phone off, open Odin, plug in USB with vol up/down pressed, right?

Not sure if this will help, but I bought a second USB cable to carry in my laptop case. If I use it I can charge the phone but cannot connect it to a PC. If I use the one that came with the phone it works fine.
I have actually tried some other cables and they have issues too. They all have a larger cable housing towards the end that plugs into the phone, where the one that comes with the phone is slimmer.
A friend at work as a Fascinate and he has the same issue, we suspect that the increased size is keeping the usb from connecting all the way in the phone.

Ive tried different computers and different cables, as well as different drivers. Ive used 64bit systems and 32bit systems... XP and Vista.
The phone itself goes into download mode, though I have to go through the terminal and use 'reboot download'. I cant use command line on the computer as it doesnt find the device... the phone never is identified to it. It just charges.
Is there any way to perform the commands that ODIN does without actually using ODIN? If nothing else, Id like to flash back to JF6 and be able to use the OTA updates. At this point, Im stuck till clockwordmod works with 2.2.

I experienced the same thing. My Captivate would charge, but it couldn't connect to any of three computers (WinXP w/drivers, Mac OS X, and Linux) with either of two micro usb cables I had. I would always get a USB error in some form.
I was on cog 2.1, and was able to roll back to the JH7 OTA update without ODIN. Afterward I brought it to an ATT Tech Center and convinced them it was a hardware failure.
I got a warranty replacement, and it didn't work either.
It turned out to be bad micro usb cables. One was the original Samsung cable, but it was loose, there was plenty of play and wiggle in the sockets of both phones.
The best micro usb cable I've found is from a Kindle. It has a a larger plastic base than the stock from Samsung, but critically it has a longer connector. There's a solid click when connected and absolutely no play or wiggle possible. It works every time.
I don't know if you can restore from 2.2 to JH7 without ODIN. Now that we have 2e Recovery on Froyo (in Cog 2.2 BETA6), could you use Clockwork Mod (Rom Manager) to flash designgear's JH7 OTA ROM?
Try some alternate micro USB cables, you might be surprised!

Im having the same issue, was there any resolution to this from the OP??
I suspect hardware also, and Ive got another Micro USB on order from Amazon and will prob buy one from a store tomorrow also.
the stock cable is horrible, I bought a nice charger the other day and it has a nice click and stay, and since I plugged it in to the new charger it no longer shows up on any computer with the stock cable. Im wondering if the new charger with a tad larger connector spread the connectors just a tad too far for the stock cord.
I tried everything as well, I hard rebooted, put into recovery mode and even deleted all my user data to try and see if there was some software that was blinding the computer to the connection... no luck
Ill let you know what I find.

Same issue here. Has anyone had any luck with a new usb cable? Luckily, I can transfer files from my computer via bluetooth for now, but it takes forever!

[Q] Computer connection problem

Hi,
I have searched, I have trown, I have do many things but cant fix this one. I was up till 5 in the morning last time but nothing. The problem I am getting appeared when I changed the usual samsung cable (which I got in box) with Nokia one, since I lost the last one Samsungs. The cable and everything is fine because it works on my notebook and there I can do everything normally.
So whats the prob:
I somehow connect my phone to the computer via media player and I can do anything with files on my phone, I can copy them to my computer BUT I cant do it vice versa, I cant copy nothing to my phone. Its just saying discovering ... and it will stay like that. In mass storage (if I get him to there ) it will lag so I have to unplug and plug it again.
Mom has the same windows 7 as me.
I have a high feeling that this has something to do with my computer being used to cable used before and I would have to delete some file from my computer (phone was already formated) ...
Oh and I have used every single USB on my computer, which is I think around 10 usbs
Restarted the comp and the phone dozen of times, still nothing.
Debuging mode, nothing appeared ...
I tried connecting to samsung kies, it wont connect, it just says connecting to a device.
Guys if you help me, my phone and I will be gratefull forever
Update: I have formated my computer also, still the same!
Update2: I will send $10 to paypal to the one who helps me with this one!

I had a similar problem, i would first ensure, that the Device isn´t connected to a USB Hub, but directly into the Computer. Sometimes the front USB Panels acts like a Hub, so if its not a laptop try to plug it in the back of the computer.
You said, you already formated the device? How? If you can do this again, then make a wipe. Go into the Recovery Mode with the 3 Button Combination and select wipe. After reboot you should have a clean device.
Do you have a external memory card inside? If yes put it out.
Now connect your device to the computer, wait until all drivers are installed. If you get any problem right here, then go into Kies and on the left top Corner where it says Kies, select Driver recovery. It will automaticaly try to reinstall the drivers.
After that you should be getting a connection to Kies.

Tried, and other then loosing my massages and contacts I didnt achive nothing :S

[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?

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

Issue with Connecting Phone to PC

For some reason, out of nowhere, my phone doesn't seem to want to work completely with my PC. I've never had any issues before, worked fine yesterday. But today, when I plug it in, and select mass storage, only the Internal Storage gets recognized and comes up for me to open the folders, but its not recognizing or showing my Removable Storage, aka my SD Card. I have restarted my phone and my PC. Unplugged several times and tried again, but no go. My sd card reads just fine when my phone is unplugged, all my music and everything I have my SD card shows up on my phone and I am able to access it through my phone just fine and move files between the two. But my PC just wont recognize it and wont show up in my computer. Any thought on why this is happening and what I can do to fix it ?

I had that problem while testing with windows 8. Try plugging into another USB port on the PC.

Just had this issue a couple days ago, I think I took out the battery of the phone and took the sd card out and put both back in

That was one of the first things I did, cause the first USB port I plugged into wouldn't recognize the phone at all, which I've had that problem quite a few times recently, but if I switch USB ports it starts to work fine, but this is the first time that it only brought up the internal storage and not external (SDcard) storage. It's still not working....

I tried that as well, someone on another forum suggested that, and it didn't help. I don't get what the problem is. You would think it would be an issue with the SDcard, but as I said in my OG post, when the phone isn't plugged in through USB, the phone itself reads the SD Card fine, I am able to access stuff from it, move files to and from, etc etc. This is pissin me the hell off tho, that's for sure !
Any other Suggestions/Ideas ?
EDIT - I forgot to also say, I put my SDcard in another phone and plugged in it via USB, and it recognized it just fine. And so then I thought, Great, its my phone itself, either the USB cable, or the SDcard slot on the phone, so not only did i try a new USB cable, but I also put a different SDcard in my phone, and it worked fine, so then i did the same thing, except with my USB, and it still worked fine, but as soon as I put my SDcard back in, it wouldn't work. I am like outta ideas here, I am about to just send my phone in, I have insurance, and since they are about to discontinue this phone, they will have to give me a different phone of equal or better quality/specs, So this might work out in my favor. I can prolly at least trade it in and get a discount off the phone i really want, which is either a LG Spectrum or a Samsung Galaxy Nexus, or possibly an HTC Rezound. I really want an HTC One X but no go for Verizon and the one i really really want, the Samsung Galaxy S III isn't out yet, and from what I've been reading in the news, it might not come out on time, Apple is seeking an injunction, preventing Samsung from Selling the Galaxy S III in the US until the Patent issues are resolved in court or through settlement. Which I hope to god that wont happen. Germany already agreed to ban the sell of Xbox360s for the time being over there, so its something that definitely could happen over here.

I don't know if it helps or has anything to do with your situation, but have you checked to make sure the phone is connecting as mass storage, and not charge only or internet connection mode?

Mass storage is the default, or the always ask. You have to actually manually go in and set charge mode or internet mode each time you want to use them.

Did you switch cables? I had the same issue when I used a generic cable instead of the VZN supplied one. Some of the imported pacific rim cables only charge (2pins instead of 4 pin usb internals) Also use the usb headers on the motherboard (rear of pc) not a hub or front ports.

here is what I did...
I used root explorer to execute the driver file on my phone. When I plugged i into my computer it ran the bootstrap which installed the drivers on my computer. It worked and linked up just fine. I then used the .tot files and got my phone to do the otas.
