[Q] Can't connect my Captivate through USB anymore

Hi everyone,
I'm having issues connecting my Samsung Captivate to my computer. For about a week, it worked fine, I was able to transfer files to my phone but recently I noticed that the "USB connected" notification is not showing on the phone when plugged in to the computer.
Now, when I plug in my phone to the computer it just charges but doesn't comunicate with my computer. A friend of mine bought the same phone right after I did and he gets the "USB connected" connected when he plugs in his.
I tried using his USB cable but again, the phone is not recognized by Windows nor the phone detects it is connected to the computer. I've tried installing several USB drivers that I've come across on several forums, but nothing. I even downloaded and updated Kies to the latest version, but still nothing.
My phone is unlocked and NOT rooted, and I'm using Windows 7 x64. I've set the USB Settings to Mass Storage, even to Ask on Connection, but it doesn't ask anything when I connect the phone to a USB on my computer.
Sometimes Windows knows there is a device connected but says it couldn't recognize it.
I already did a factory reset, but the issue was not solved. I've tried connecting it to other computers, but still hasn't been able to connect my phone correctly.
What could it be?
Thanks!

Hmm. You have Mass Storage selected and up-to-date USB drivers. Try selecting USB-Debugging and Stay Awake in the Development option of your phone. If that doesn't fix it, then I have a few other ideas.

Make sure the usb door is completely open, it should click into place, some users have reported this solves their usb issues.

I did what you told me, but still my phone ain't recognized by Windows nor my phone is aware that it has been conected to a computer
What other ideas do you have in mind?

I'm sure usb door is completely opened

Have you tried using a different USB outlet on your computer? I had this same issue when I plugged my phone up using the USB outlet on the front of my computer then when I tried the one on the back of my computer it worked just fine.

Are you running a launcher app? I use launcher pro and can't connect until I change back to the default launcher with home switcher and launch it.

First off, think back. If it worked for a week and then suddenly stopped, what changed? Maybe you updated something on Windows or changed something on your phone. There's a reason it just stopped.
You can try using a free program called USBDeview.
It might do the trick for you and help you install the correct drivers. I'm thinking you no longer have them.
1. Download USBDeview (link is above)
2. Plug your phone in and open the program. Find all the HTC drivers-delete them
3. Unplug your phone and plug it back in
4. The correct drivers should install automatically
You can also try updating the drivers manually.
Galaxy S drivers (These are for ADB, but will work fine)
1. Click the Start Menu on your computer and right click "Computer"
2. Choose "Manage" --> it will ask you to continue --> "Device Manager"
3. Plug you phone in and look for it to pop up, probably under Portable Devices
4. Right click --> "Properties" --> "Update Driver" --> "Browse" --> "Let Me Pick" --> and navigate to the location you extracted the drivers to.
This is most likely a driver issue. I doubt your phone is messed up. You'll get it eventually. I also had a hard time getting my Captivate to connect. After uninstalling and reinstalling my drivers (more than once) it finally worked. One last thing, for now. When you uninstall drivers, also make sure you don't have any installed under your program list. As in, Control Panel --> Uninstall a program. Good luck!

A friend of mine, who bought the same phone on the same day as I did, plugged in his phone on my computer using my cable to the same port my phone was connected, and he did get the "USB Connected" notification on his phone

I just did the new AT&T update and mine is now having this problem. I have to manually go into manage applications > usb settings > mass storage to get it to work now

I did all that yesterday, but the device ain't listed in the USBDeview nor it shows up in the Device Manager

did you finally fix this problem? because I'm having the same issue here

Same here. It was working fine, I could connect to Kies, transfer music in Media mode and see both sd drives in Mass Storage mode. Then I rooted today and now I get nothing. In anything but Kies mode I get the Windows Bong of Recognition, but still not visible in Explorer. Also, my Home screen stays active instead of switching to the USB animation like it did before. I know this can't be a consequence of rooting the phone, can it?
EDIT: More weirdness, with the phone connected in Mass Storage mode if I look at My Computer in Explorer there are 2 extra drives showing, but they are greyed out and when I click on either of them it asks me to insert a card as the drive is empty. WTF???

UPDATE: I unrooted and managed to get my USB connection back to working. It is still a bit flaky as I sometimes have to disconnect/reconnect several times before it works, but at least it now works although it sometimes loses sync in the middle of transferring a file. Can't imagine why simply rooting the phone would cause the loss of USB connectivity. I am going to reroot and see if it occurs again.

OK, a rerooted the phone and this problem is now back. I have no problem connecting while in debugging mode. I installed OCD (non-Market apps mod) and when I turn off debugging and connect I get the Windows bong and see the USB icon in the Notification bar, but the MTP screen never comes up and I can't see the phone in Explorer (Mass Storage mode) or in WMP (Media mode). Kies can;t see it in that mode, either. I really don't want to have to unroot every time I want to look at the phone contents. Any ideas? PLEASE!

I'm having a similar problem - I installed the Perception ROM and immediately afterwards I can't see the USB connection at all from my PC or my Mac. The USB icon on the phone does not come up either.
I'm trying to get my hands on a different cable - but the weird thing is when I plug the USB into my computer the phone starts charging for like half a second and then stops.
This is really annoying. I tried changing the rom to Cognition 3.02 but that didn't change anything.

There are a few topics on this here on the forum - I would recommend the following:
How are you rooting your phones? Nobody has said exactly how they are doing this. Are you using recommended rooting methods? Or are you using some app found on the market?
Make sure you have USB De-Bugging is turned on.
Make sure you have it listed as ask on connection.
For those who can see the drives in Windows...
Plug in your phone and then pull down your notification bar and click on the USB connected message. It will give you an option there to mount your SDCard(s) to Windows allowing you to transfer files.
Kies is junk - I'd recommend uninstalling it as it seems to cause more issues then it solves.
Use the drivers I have posted in the Q&A section (these are the ones that are linked in Design Gears Odin 1 Click Back to Stock post btw) - but I would try and COMPLETELY removing the pre-existing drivers before installing the new ones.
Make sure the USB Cable is plugged into the back USB port that is directly on your motherboard - this will ensure it's not a computer/hardware related issue.
I know of one user who had to go through his computer and manually remove all remnants of other drivers. I have my phone connected to both a Windows XP 32bit and a Windows 764bit systems and have been lucky to not have any USB issues.
If none of that works - I'd suggest taking it to your nearest AT&T/Rodgers shop and see if they can get the phone to connect (make sure it's back to stock!). If not they should warranty replace the device.

This isn't my first rodeo... But to answer your questions:
I used the rooting method posted in XDA forums - the one-click rooting.
I've used the drivers included in the xda-forum. Not the kies software.
The only thing that changed was the loading of a new custom rom. The cable works (confirmed on my friend's phone). I can't get odin to restore back to stock because I can't get the computer to recognize the phone in either normal or in download mode. I've restored to stock using the jh7 in the stickied q&a thread
I don't think it's a hardware issue either - I think it's software-based. I'm going to try to take it to an at&t store today at lunch to see what they say.

I also have that problem only I noticed it when I cleared the dalvik cache. It messed up the auto rotate so it was always sideways and now I have no connectivity to the PC. Let me know how ATT treats you.

[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

My sons got two hd+'s for xmas and I'm in the process of attempting to connect through adb, which I have done many times with v various phones, yet when I plug the nook in I hear and see it connect and then immediately disconnect over and over again. Ideas?

It seems its only when I'm in usb debugging mode. Both are doing it.

I've rooted, installed GAPPS and so on many Nook HD+ tablets; most for my friends, since they have no idea how to do it. I've noticed this problem occurs due to the Nook not being installed correctly in ADB mode.
What I would recommend is going into Device Manager, find "Android Composite ADB Interface" and make sure it has a green-chip-like icon on the bottom left corner of the icon. If not, then it's not functional. To solve this, once your tablet is connected, it should be detected as a media player/portable device, with the name BNTV600 (I think it is/was - all this is still in Device Manager by the way). Right click on the device, and attempt to change the portable media player into a "USB Composite" device. That should solve the trick.
If you're still having problems, I can connect to you via TeamViewer remotely to access your computer, whilst your tablet is connected and solve the problem for you (if I can). If you'd like, I can completely root your tablet for you. I've done it for a couple of friends over TeamViewer, so if you'd like, I can do it for you too.
Best of luck.
P.S. Try disabling "USB Debugging" mode and set "Enable ADB".

[Q] Connecting to computer problems

Hi all!
I have a Nexus One running CM7.2.0 with Clockworkmod Recovery. My computer is running Windows 7.
I want to connect my phone to the computer in order to return it to it's factory state with an official shipping rom and stock recovery image.
However, I've run into a problem which I've been having for quite a while now; when I plug the phone into the computer via USB cable, it charges, but nothing happens on the computer, and nothing happens on the phone.
I've tried different USB cables, and different computers.
If I push the part that goes into the phone port to the right, the computer will make a noise as if to say that something is connected, but then it will be unable to install the correct drivers, and will say "USB Device not recognized" It comes up as an "Unspecified" device in Devices and Printers, and in "Unknown Device Properties" it tells me that "Windows has stopped this device because it has reported problems. (Code 43)".
I have a feeling that the problem is the port on the phone, but I wanted to ask on here first to see what other people thought. Why is it that the phone charges correctly, but won't be recognized on the computer?
I might just add that this problem first started when I installed a device manager program that allowed me to see my texts and things when the phone was plugged into the computer. It was a while ago, and I think I remember (not entirely sure though!) not safely ejecting the phone before unplugging it, and then 2 minutes later when I went to plug it back in, this occurred. Whether this is related to the problem or not I do not know.
Also, I'll add that this problem has been occurring for quite a few months now, but it is only recently that I have noticed that when plugged into a wall charger, the phone charges much slower than it used to, and the charging light will go on and off every so often. This suggests port wear, but this started happening quite a while after the connection problems happened.
Anyway, thanks to all those who respond! I am keen to work out what is wrong.
Thanks,
Simon

Also I'll add that the SD card works perfectly fine in an SD card reader USB thing!

I'm not sure you properly read what I said..
My phone doesn't work on any computer I try it on. All other USB devices work fine on the computer I am currently using. This means that it is not simply a matter of following the steps you linked, because the problem is not related to a windows error.
BTW, learn how to read properly.

Please help, not getting phone prompt when usb debugging enabled

So I was happy remaining on stock with my watch until a number of things happened: I flashed stock lollipop on my note 3, expecting a few things to break with android wear, and sure enough, the watch has problems reconnecting to the phone after it has been out of range for a few minutes (fixed only by restarting the phone). This annoyed me, but there was no going back on my note 3. So I thought to hell with it .... I'll root the watch and flash the urbane port, which should give me wifi, maybe that will help.
I haven't had to use adb in 5 years, so I'm a bit rusty, and android sdk kind of scares me now.
But I marched on. I got hold of the google usb drivers and got my watch detected. Or at least so I thought. I downloaded "fastboot+adb.zip" from somewhere so as to avoid messing with the full sdk, and tried "adb devices". Device detected, but "offline". Every guide I read mentioned that when the watch is plugged in after the drivers are installed, the phone should prompt you to enable wear debugging. That never happened. And I've removed the drivers and reinstalled them countless times now (but I don't see why the driver pack from android sdk website wouldn't work). The watch is listed as "Android Composite ADB Interface" in Device Manager. Oh, and I'm running windows 8.1
ANY help at all would be greatly appreciated. I realize this is extra noobish but I'm just out of practice, honest. And I'm kind of suspecting that the watch just isn't playing nice with the note 3's new lollipop. In which case I'm kind of screwed.

Had the same strange problem, took it to the service centre and they changed the logic board. When you connect it to the computer via usb does it recognise it as watch or unknown device ?
