Hello Guys...GretoVerno here fellow Samsung Galaxy S Vibrant Owner...
I have this phone and everytime i connect it to usb i Get the Message
"USB Device Not Recognized" error message...I have installed all the drivers i could possible find on the internet and the error still pops up...i ahve tried using the phone in USB Debugging mode to no avail what so ever...
Someone Please help if there's a genius out there...I really love this phone
Uninstall the Samsung drivers off your computer. Then reinstall make sure that have the correct version windows 32 bit or 64 bit for the correct operating format. Make sure you give admin rights to it. you can find these drivers in the Noob bible by S15274N in the Gen section. I am assuming there is not a problem with your phone. If you have a friend, check it on their computer, that's an easy way to rule out phone issues. That should resolve what ever problem you have.
There ia another way to check, that is have a friend with odin (or you) and see if Odin recognizes, if it does, then you got it solved or at the very least Odin back to stock and reinstall a new rom, this will solve all these issues as well.
Hope you get it, good luck
Had an issue with my brother in laws comp not recognizing his vibrant. Took an hour or two to get his phone recognized. I think we ended up using the drivers from pdanet instead of the official danny drivers. First try getting your phone to work on another comp. Will help narrow down the issue by 50%

Windows cannot recognize my vibrant!
Hopefully someone can help me out as I am having the
same problem with my computer not recognizing my phone.
The thing is that I am already running Froyo stock 2.2
and at the time I was able to update it to 2.2 my
computer recognized my phone without a problem. I have
been reading the forums for a while now and the only
time anyone had this problem was when they first bought
the phone when it was released but here is my problem.
After updating Kies mini and installing the official
Samsung drivers from the Samsung website I plug in the
phone and i get the error that windows does not
recognize the device. I have tried this on Windows Xp
and Windows 7 on 2 different laptops and got the same
error everytime. So what I did was while on Windows Xp I
uninstalled the unknown driver and I kept plugging and
unplugging the phone and uninstalling the unknown driver
until I got my computer to finally recognize my phone.
Once my computer recognized my phone I Then started
downloading the recent update, when the download was
done as soon as my phone went into download mode my
computer kicked out my phone and gave me the error that
windows does not recognize the device and at that time
Kies mini gave me the emergency recovery notice which I
didnt have to use because the phone booted fine without
fail.
You should also know that prior to the recent
update from tmobile for minor bug fixes I tried to root
my vibrant using the superoneclick root program. Upon
doing this after fighting with my vibrant and my laptop
to communicate with each other my computer recognized
the phone and I attempted to root. Then I got the
looping message and at that time windows did not
recognize my device which then messed up my modem and I
had to do a system restore. So after weeks of fustration
trying to root and now not able to downlaod the recent
update I am now asking for your help as XDA has been
there for us all. I have tried samsung drivers, kies mini
drivers and pdanet drivers and get the same windows
doesn't recognize my device everytime. Does anyone have
any ideas as what I can do to get my computer to
recognize my phone as I can not do anything until my
computer and my vibrant get along. Your help is greatly
appreciated XDA thanks for all that you do!
do you guys have Samsung kies installd??

can you try a different USB chord?

You know that's the only thing that I haven't tried should I pick one up from T-Mobile or were should I get one?
I am getting the same error and i tried a buddy's cord and it still did the same thing. Not really sure what happened. My phone was working fine just a few days ago. I am wondering if it has anything to do with the large amount of Windows Updates that just happened.
Try uninstalling your drivers and install these. I had the same problem and then I used this and it has worked on every computer. Heck even worked when I hooked up my SGS2
http://www.multiupload.com/FUL878MTJH
I had the same issue. It is a phone problem and I had to get a warranty replacement. No combo of cables or drivers would fix mine.
Well after uninstalling and reinstalling, trying new drivers, restarting countless number of times, troubleshooting through the device manager, I had the genius idea to restart my phone in a last ditch effort before i gave up and it worked.
Now i feel somewhat like a dodo. Rule #1 - Restart

Have you rebooted since you installed the drivers?
Well I tried those drivers from that link you provided and no dice. Im going to pick up a new usb cord from Tmobile tomorrow and see if that might be the problem. I can always use a 2nd cord for charging I guess.

That would be the logical next step.. just to verify, you have restarted the phone and computer since installing the drivers right? If you have then its most likely the cord. Its weird these cords seem to have been giving me problems more than any previously owned ones ie regular usb or even my amp cord which I step on and rip out the amp more than i'd like to admit

Makes sure that when you uninstall your drivers to restart your PC then reinstall and give a shot. Of course, also make sure you are using the right 64x or 86x driver.

Hello all,
I have a Samsung galaxy S II purchased in Israel from Cellcom.
In my ill advised attempt to unbrand, and thus accelerate, improve memory and battery consumption, I flashed a stock ROM which I believed to be the latest.
The phone works great, with one exception. There seems to be no way to connect it to PC, be it WIN7 32bit or ubuntu 32bit. original usb cable or other cable, my stationary workstation or my laptop, be it USB Storage mode, USB Debugging, that stupid Kies mode, and most importantly because i'd like to flush it back, no Odin Mode. (in win32 - any mode gets "unknown device" status like the device doesn't publish it's name correctly or similar.)
moments before the flash the phone connected in all modes.
I think i've pretty much covered all of the obvious. and there is no problem with my latest sdk and drivers as my Nexus S still connects to both PC's with great success.
SO some info - and what I have already researched.
from http://forum.xda-developers.com/showthread.php?t=1113928, I gather that the PDA on my Cellcome bought SGS2 is either JIKG3 or JIKJ1. and that it's a GT19100T and I gather that denotes some kind of hardware specification.
the ROM I've flushed to my phone has this name:
GT-I9100_XEU_I9100XWKJ3_I9100XEUKH2_I9100XXKI3.tar.md5
everything seems wrong about this ROM in hindsight but, the worst is that it has no T, and probably isn't very hardware compatible. (though the telephony, wifi, camera, sensors and anything I tried works).
The phone is not rooted as after flushing I have lost any USB connectivity. I therefore cannot try and manipulate system files, to try to recover that way.
I have tried to root with the exploit apk. to no effect. I gather it's a statistically challenged way of rooting so I'll try my luck a lot more during the wait for your answer, and report any success.
**Edited**
the "Easy Rooting Toolkit" on http://forum.xda-developers.com/showthread.php?t=1319653
I'll try to run it as best I can, with the shell emulator, instead of on adb, but with debugging enabled.. although it's not a very East Toolkit, when I use it this way..
I'll still report any progress..
**/Edited**
I have seen no one on the internet with this problem. it's really a very stupid problem to have. but a problem nevertheless.
Any insight as to the moves I can try next will be greatly appreciated.
Any information I can add with my limited usb connectivity will be gladly shared. (my "Kies air" works so I can upload to storage that way.. plus i have a shell emulator installed..)

Alex.

just the single one.
There is absolutely nothing wrong with the ROM itself as I have been using it on my phone for a couple weeks now.
The problem exists between your phone and your PC, the PC is stating that it's an unknown device after all.
What I would try is to un-install the device in Device Manager, unplug the device and restart the PC and then plug the phone in again, if that does not work, I would throw in a factory reset of the device itself while repeating the above steps
I think i've pretty much covered all of the obvious. and there is no problem with my latest sdk and drivers as my Nexus S still connects to both PC's with great success.

What do you mean by that? The nexus drivers have nothing to do with the galaxy drivers. Only if you run an AOSP rom you will need those drivers. Not if you run a stock rom.
Am I right that your pc sees the phone, but does not recognize it? Did you try reinstalling kies? And then from within kies tried to reinstall the phone drivers?
your PC may not recognize the device after the radio or kernel is changed. what I did was uninstall every single usb device from device manager and reboot, fixed.

jamesyb0i - I saw that some people have been successful after uninstalling all usb devices, I'm challenged in this task as my keyboard and mouse are USB. I will try it on my laptop as soon as I'll get access to it, though because of the wide range of computer and OS I've tried I'm pretty sure the effort will be ultimately futile.

Lennyz1988 - I see your point about the ADB Driver for the Nexus S, but as for the other advice.
As I said, I extensively tried to run it on multiple PC's multiple OS's.
I did try to uninstall / reinstall kies, and kies drivers.
after that didn't help. I got an SGS2 from a friend, just to try it on my computer.
it worked just fine.

The problem I believe is specifically because of the GTI9100/GTI19100T differences
I'm sure as achillies400 said that there is nothing wrong with the ROM itself. BUT the problem is not with my PC's it is more likely the different hardware, and the hardware driver on the phone itself that makes my phone become an "unknown device".

You could try this exploit.

Don't know if it will work for you but it's worth a try.
Extract the .zip to /data/local/ on your phone and run the commands.

!!!!!!!!!!!!!!!
I have the same problem, and I couldn't find anyone else w/ it or with answers either.
almost all the same scenario except I have an SGSII AT&T I777 that started out as UCKJ1 and is now UCKH7
My phone started coming up as unknown device. I can not find any remedy to the solution.
Here's my scenario: http://forum.xda-developers.com/showthread.php?t=1372171
My guess is I might try to uninstall "new" programs that I added to the phone and PC, uninstall kies etc. and drivers, and maybe try and do a restore or refresh or something on my phone and see if I can get to "scratch" and re-start from there.
I installed winamp on phone and reinstalled it on PC for wifi, and it kept mounting/unmounting my SD card from phone to computer each time I plugged it in (I think that messed with my card possibly giving it "unknown")
Or also when I changed my Kernel may have made the phone unknown. Those are the only 2 changes I can assume did this to my phone =/
any update on your phone?
UPD: My kernel was causing all my problems. Restored to an earlier backup and it had older kernel. All problems were relieved.
It seems like I go through this every damn time I get a new Android device, so you'd think I'd have figured it out by now, but I haven't.
How the heck to I get ADB working for this device? It's not being recognized by the "adb devices" command right now. As far as I know, I've got the drivers installed (at least, I could communicate via fastboot). I don't know what else I need to do, and would appreciate any help.
How did you get install the drivers? If you haven't done so, you can just grab the drivers from here: http://forum.xda-developers.com/showthread.php?t=1992345

Yes, that's where I got the drivers (and that's how I got fastboot working).
I've taken the drastic step now of uninstalling the entire SDK thing and am currently re-installing it. We'll see how that goes.
EDIT: yeah, "adb devices" still gives nothing at all.
You need to turn it on first but Developer Options are hidden in Settings. Go into About phone and tap the build version. After 7 times you will have access and you can turn on USB Debugging

do you have usb debugging on? its under development under settings. to make it appear, you need to press the about phone 7 times or so. http://www.androidcentral.com/how-enable-developer-settings-android-42

While this was, admittedly, once my problem back in the early days of android, it's not the problem this time. USB debugging is on.
EDIT: I've also reconfirmed that fastboot is still working after the whole re-installation thing.
Anyone have any other ideas? Is it correct that when I plug the phone in, it's detected add an MTP device?

That's all I can suggest as well, although I can't see what the issue could be
Yer try installing the SDK and downloading the "Google USB Drivers" from there to see if it helps.

Here try this. It's from the sdk. I just zipped it. https://www.box.com/shared/7sutkummukh4pup0rwoi

You can just get the windows executable from Google, r21
http://dl.google.com/android/installer_r21-windows.exe
Thanks, everyone who's been reading/trying to help. Unfortunately, it's still not working.
People suggesting the .exe installer - that's how I've installed it each time. Twice now I've uninstalled/reinstalled the SDK. When installing, I choose the SDK tools, SDK platform tools, the 4.2 API (which is probably unnecessary, right?), and the Google USB driver. Each time, ADB has worked *in general*, but will not recognize this device (via the "adb devices" command).
Here's how things are going right now. When I first plug the phone in (with debugging on), if it's not currently installed as a device then it automatically self-installs and shows up as an "mtp" device. I try ADB, doesn't work. I then go in and manually install the drivers found in various places around this board. When I do this, it no longer appears as MTP. This is weird, though, and I didn't notice this last night - when I look at the list of devices in Device Manager in Windows, the category it falls into is "ASUS Android Devices", under which it's listed as "Android Composite ADB Interface", and it still doesn't work.
Something seems wrong about it being listed as ASUS, though. I wonder if all these current difficulties are a result of the problems I had getting my Transformer Prime to work with ADB? If anyone sees anything above that looks like I'm doing something wrong, let me know; I think the next thing I'm going to try is doing this whole process on a fresh computer here at work that's never been exposed to android at all, see how that goes. I'll check back in after I do that.
Have you tried these drivers?...

I have, and it still doesn't work on my laptop. However...
It's working! On a shared computed at work that had never had *anything* android-related installed before. Went through the same procedure I did on my own computer, so the problem is with my laptop, I guess. Which I'm more okay with than it being a problem with the phone. I guess I need to more thoroughly remove everything from the laptop, maybe?
An update:
I DO. NOT. UNDERSTAND. why this worked; I haven't changed the drivers or anything on the laptop itself. On a whim, I changed the device type on the N4 from "media device" to "PTP device" and suddenly ADB is recognizing it on the computer where it's never worked. Should I have expected that?

I have to do that to my Nexus 7 before ADB will recognize it, so you're not alone there.
Just curious, what brand phone did you have before? If it was a samsung and you had all the samsung drivers and what not installed still, this could be causing the problem. My cousin couldn't get adb to recognize his device and we finally discovered the samsung software was conflicting in someway. He uninstalled it all and adb worked like a charm.
I had the same problem, here's what you need to do. When you plug it in, change the settings from MTP to Camera for USB settings. I don't know why, but you need to do it.

I've got four other android devices that all worked (simultaneously, at that): T-Mobile/HTC G1, Nook Color, T-Mobile/HTC G2, and an Asus Transformer Prime.
Hi, been lurking around here for a good while now....fantastic website website and I've learned so much but now I have an issue.
For what ever reason my nexus 7 will not boot, I can get into fastboot and have been following the guides to do a full factory restore through fastboot. Everything goes fine until is comes to "Sending System" then just.....stops. I have used the nexus toolkit and also the official sdk drivers and fastboot contained there. I only have an old laptop as my main pc for some reason does not recognise the nexus.
I have tried alternative USB cable too.
Does anyone have any other advice.
Also the device is complete stock no custom rom has been installed so no custom recovery available.
I really appreciate any help.
Cheers!
Okay well ive managed to get it back alive!
used a new laptop and usb cable and it all seems to be fine now!
Now back to my original issue...windows 8 is pissing me around and wont recognise the bloody thing!
Any ideas?
Try a search, shouldn't be hard to find what others have done with Windows 8 difficulties...

Go to Device Manager, show hidden devices and uninstall any Android or ADB related devices that you have. Disable USB debugging on your Nexus, then plug it into your PC and see if it's recognized. If it is, then re- enable USB debugging, then go to Device Manager and reinstall the Google USB drivers to get ADB support back.
Thanks for the advice, first thing I did was try searching....I have tried countless methods suggested but nothing works its like windows cant find the drivers. In the device manger its recognised but no diver installs no matter what I do. If I force the manual driver install it fails!? I have tried the Naked drivers, the SDK even making sure the media components of windows are installed properly
A little history. I have rooted several other brands of tablets, so I am not new at this. Even thogh I am not a programmer by any stretch of the word. My Pixel C drivers work fine in normal mode, I can see the storage as a drive, no problem. I can transfer files back and forth. But, when I boot it into fastboot mode, it will not see it. It is listed as an unknown device in the device manager of Windows 10. I have tried to install the drivers, but they say not found. And this is the driver from the Android website. I'm at my wit's end. I'm not a newbie at windows, either. But, I need suggestions to get this to work. BTW this is the latest version of Windows 10 1903. And I have tried every solution I have found on google and on this website. TIA
Ok, fixed that by selecting a driver from a list of drivers so now I have ADB drivers. I have another issue which I will do some research on if not.....I'LL BE BACK.
What is your goal?
Do you want to use adb or fastboot?
Is the bootloader unlocked, have you enabled usb debugging in the developers menu (hidden) etc
Ok, as I said before, I figured it out. And yes, the bootloader was unlocked and yes USB debugging was enabled. I got everything
working and I am now running Android 9. Thanks for the reply, though.
