For some odd reason, I lost adb functionality (i.e. any adb command issued receives "error: device not found"). I looked in Device Manager and noticed that MyHTC was gone! I looked at my phone and USB debugging was enabled and in charge only. I could put it in USB Drive mode and the PC would recognize it as a USB Mass Storage Device so that I could exchange and view files but no adb.
I searched and searched on this issue for hours and installed over a half a dozen "androidusb.inf" driver files several times over. Every install generated the Code 10 error where Device Manager was lacking some information from the driver file and could not start the device. I reinstalled HTC Sync and gave that a try...nothing. Downloaded USBDeview and uninstalled all HTC drivers including the HTC Android USB Device and tried again to no avail. WTF?! What else am I supposed to do?
Well, in a "what the hell, let's give it a try" kind of moment, I decided to toggle the USB debugging off and then back on (and yes, it was checked and on the whole time). WORKS!!! WHAT THE CRAP?!! MyHTC is back in Device Manager and everything is back to normal. I'm glad but irritated!
I share this story in hopes that if someone else stumbles on this problem, they will not have to go through the same headache as I did. Just thought this was odd considering how many times I have plugged and unplugged and never had any problems with adb.
Toggle USB Debugging....so simple. *rolleyes*
Same Issue
I've got the same issue on my EVO 4G. Just installed the latest CM7 and now it tell me device not recognized. If I manually install the drivers it gives me the same code 10. I can't bring up the phone as a storage device and toggling the debugging is not working. Any ideas?

You installed the hboot drivers correctly?
Boot into recovery, with usb debugging enabled, connect to pc, it should install the drivers.
Still the same
Even when I reboot into recovery it still gives me "USB Device not recognized." I previously had MikFroyo on my phone with no problems. I'm at a loss.

You most likely have a bad cable, do you have another one you can try?
Possibility
Not at the moment but that may explain it. Still seems weird for it to just go out right as I change to CM7, but still a possibility. I am going to run and grab my other cable. Thanks for the advice.
No Luck
The new USB cable didn't fix the problem. Also, in device manager, even with the driver installed its labeled as "unknown device."
If I boot into hboot the computer recognizes it.
**update: After rebooting from the hboot, my phone is recognized by the computer however, a disk drive is not coming up in "my computer." I have USB storage turned on but Im not getting anything.**
Any help would be much appreciated!
Sad Day
Apparently the Micro USB port on the bottom of my phone is going bad... I talked with some other people who've had the same problem. HTC knows that the ports aren't very sturdy as well. Well... sad day for me.
Also if you're getting the notice from windows saying that you your device will run faster in a 2.0 usb port and you know the port is 2.0 ... chances are your port is going bad as well.
*****UPDATE*****
Flashed to MikFroyo and none of the above stated problems. I would venture that it was CM7 but apparently everyone else is able to use it so who knows.
I connected my SG2 via USB cable to my PC and started seeing this error
"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."
I have tried everything from changing cables/PCs/enabling/disabling USB debugging to *#7284#, and none of them work ...
Is the device bricked, is there any hope of revival..please help i got this phone myself paying $400
Does your phone turn on and work and a connection to PC the only problem? If so your not bricked...you prolly need to install the drivers in order for your PC to recognize it so install kies on your PC

Yes phone turns on, charges through the port...just that it is not recognized by the PC....what could be wrong?
As I said previously you probably need to add the drivers on your PC install kies on your PC

Make sure you use one of your rear usb ports also. I had an issue with drivers installing in a front usb port.
Phew it turns out to be the samsung driver..I believe kies update must have corrupted and stopped the pc from recognizing the phone....

The definition of "bricked" is having a really expensive
... brick. It means your phone doesn't turn on no matter what you do to it (short of a JIG and that's not guaranteed) the "USB device not recognized thing" is a problem w many windows devices my vista computer does it all the time and I just switch ports.

Having same/similar issue
Hey, was there every a solution found for this?
I'm having basically the same problem...using the cable that came with my phone, and have installed Kies (fresh). I have tried toggling multiple settings. I tried uninstalling kies and reinstalling. I tried using pdanet for the driver. I have tried a few different roms, as well: Darkside 2.4, 2.5.1, and gingersnap 1.21. All have had the same result.
When I plug the phone in, it beeps (charging) but no notification for usb settings (disk drive, sync, etc). On my computer, it pops up "USB Device Not Recognized" and says the device has malfunctioned, etc, same as OP.
In Device Manager, it shows under USB as "Unknown Device".
I have tried this with two Windows 7 laptops, and a Windows Server 2008 R2 desktop. Also tried with a different cable. This cable was able to transfer data from an external hard drive today, so I doubt anything is wrong with it.
Any help is greatly appreciated!

Did you try the drivers separate first or Mtp mode
Sent from my revolutionized Samsung infuse
I tried without the drivers, and went to wireless and network > USB utilities. The only option in there, however, is "Connect storage to PC". If I try that, then plug it in, the phone acts like I hit the back/undo button. It doesn't show that anything is connected, nor does it give any other options. At this point on the computer, I get the "USB device not recognized" error.
This happened before installing Kies/Drivers, and still happens after installing drivers and kies.
try another usb cable
i had the exact same error, and it ended up being a good USB cable that went south
I will try a different cable when I get home - Have a month old cable for a mytouch 4g that I know works.
Okay, I tried it with the other cable, on a desktop in the rear port. same thing...Phone start to charge, and I get the error that the device malfunctioned, yada yada.
Any other ideas? Should I try to connect in Download mode?
Alrighty, so in the end, I ended up completely unroting, using terminal emulator to remove superuser.apk, busybox, and su and putting right back to read only. Then in CWM, flashed a stock 2.3.5 ROM (Zedomax). However, I now have the 2.3.5 ROM and the 2.3.6 KL1 Kernel...
I'm planning to return to Tmobile/Samsung - will the kernel and rom versions not matching be a huge red flag??
Any help is appreciated. I have tried to flash the 2.3.5 kernel, but I always get an error that it's not signed/verified.
Ideas?
I was hoping to grab the 2.3.6 OTA update, but it says there is no firmware update. Is there an update file I can put on the SD card and update using the stock recovery?
UPDATE:
I called T-Mobile Customer Service today, and went through the "troubleshooting" with them again. They ended up sending me a new one, overnight. They didn't ask anything about doing anything custom with it like rooting or other modifications.
I'm not sure if it made a difference, but I'm within 90 days, and also have the "best" insurance/warranty coverage through T-Mobile, and whoever their insurance provider is that I signed up for when I bought the phone.
Final charge is for $5, which I was told is some kind of fee from Samsung, but will appear on my bill.
Anyway, not too bad. Can't wait to get rid of touchwiz again when I get the new phone!

FYI, I just went through the same thing. Decided to finally root my phone after owning it for 2 weeks.
Phone nor the phone would recognize USB data, but would charge. Tried another cable and no luck.
Rebooted the phone. Works like a charm now.
Hi All, I've got a USB connection problem with my Galaxy Nexus. When I connect it to a computer, it will start charging, but doesn't show that it's connected to a computer and the computer doesn't show that a device is connected. I've tried on a few different Windows machines and don't get any change in the device manager. There is no "unknown device" nor device with an error. I've been searching the Internet and this forum, but still can't find the problem after a couple of days. Here's some details and things I've done:
I did not install the "force fast charge" kernel mod.
I've tried a couple different cables and verified that the cables worked with my wife's Galaxy II.
I've tried several different computers.
I've tried MTP and PTP storage options.
I rebooted everything several times.
I drank heavily.
I tried a factory reset.
I updated Windows Media Player to get the latest MTP software.
I installed drivers packages even though it never gets to the point of installing drivers.
Does anyone have any other ideas before I smash this thing with a hammer?
Does anyone have any ideas? At this point, I'm thinking there is a hardware problem.
Go into Menu -> System Settings -> Developer Options -> Turn on USB Debugging.
Not a guarantee, but something to rule out.
I've got USB Debuging on. Thanks for the reply.
Can anyone help? I'm having the same exact problem. My phone charge but is not detected by my computer. I am having this problem right after flashing AOKP ROM B35. This is very important, one mistake and my phone will be bricked as a computer to phone is so important !! There is nothing detected at all under device manager. Tried it on several laptop to make sure it isn't just my computer.
someone?
Uninstall the drivers you have for the s2. Reboot and install the official drivers for the galaxy nexus. Reboot. Then try.
If that doesn't work... let the phone load a while and just keep trying other ports on the computer. I saw this with my other gnex that it would take a while to realize a USB to be connected. Also make sure the USB is in completely... don't jam it in but make sure you know its All the way in. ( no pun intended) What's funny is my gnex will detect it instantly... but the other one takes a few tries.

Thank you dude. It doesn't work. Prior to installing this rom, my nexus is detected instantly. There is something wrong with the process i root or something. Now i can't do anything as It is not detected by my computer. Someone please help.
Indeed is the rom that is causing the problem. I opened NEXUS toolkit and rebooted my phone into boot image. It will sense it and i can operate from there. I've restored to factory and now my phone is being detected. I hope the thread starter gained something out of it too
Hi guys.
As the title suggest I've run into a USB brick with my Desire HD. I don't know how and can't remember when but it was well after I was flashing custom roms. Basically when I plug it into any PC with any cable it says "USB device not recognized". The phone thinks it's just charging (charges fine otherwise both on PCs and with the normal AC adapter). When I'm in fastboot or hboot it won't say it's in USB mode either.
When I try using Fastboot and ADB on my computer it just says there are no devices connected. I've tried many roms, both with Sense and without going from gingerbread all the way up to ICS and JB with no luck.
I cannot find any solution to this problem anywhere and was just wondering if someone stumbled upon a fix?
My thanks in advance.
Huzi.
[Update]
Plugged it into the USB 3.0 port on my brother's laptop. It turned the phone off. Turned it on and it started installing drivers and it works on there. Haven't tried it out on anything else yet as I'm backing up the files. It turned off the phone and installed it on my computer but didn't work last night. I guess I'll try again once all 11GB are copied over

Same things happening on my one XL. this post is ancient For mine even using RUU doesn't work it goes like device unplugged/cannot be found or something similar. ill try usb 3.0 when i get back to my desktop but this kinda sucks. I just had it repaired days ago.
A few weeks after rooting and installing CM10 on my GS3, it stopped recognizing any form of USB data connection. It still charges from both computer and wall adapter, but I cannot initiate a data transfer or recognize my device using ADB.
I have tried:
three different OEM Samsung cables (from SG3/SG4 phones)
all the ports on two different Win 7 laptops
all the ports on an Ubuntu desktop
enabling or disabling USB debugging
with different combinations each time. No "USB connection" dialog has shown up on the phone, and no "new device" dialog has shown up on any of the computers. I know that I can get ADB working with a different Android phone (HTC Inspire 4G) so I know that my main laptop has USB ports that work and the cables I've tried work as well, so I'm left to assume that the issue is with the GS3. External visual inspection does not suggest the USB port on the phone is damaged, and the phone is only a year old, so I don't believe that is the cause.
Is there a system setting that I may have modified on the GS3 that would disable all forms of USB communication?
(The end goal is to get at least ADB working so I can try and recover some deleted files from the internal memory; I haven't found a reliable method that does not require ADB so I'm trying to get that to work. I know that transferring files on or off can be accomplished with the external SD card or over Wifi but that is not what I'm looking for)
Any suggestions from anyone?
I am not sure. Could be a software issue. I would try backing up your current cm ROM and try installing a fresh touchwiz ROM to see of that works, to rule out software issues. This could also be a android 4.3 issue. Could try stickmount or a similar otg app from the market.

I don't think any OTG app like stickmount will help; I'm not trying to connect devices to my phone. I'm trying to get my computer to recognize my phone (and vice versa) in order to get ADB working.
If I can avoid flashing a RAM I'd like to, because I'm still interested in recovering those deleted files. If that is the only thing that would help, though, then I'll do it. Any other suggestions?
Install Kies and that should get the drivers for the pc in place. Odin should recognize the device when it is in the download mode. If that works, then the pc to phone connection is OK and I'd look to software instead of hardware.
Or, if you boot into your custom recovery, either CWM or TWRP, you should be able to get ADB to recognize the device and issue commands including pulling the files on Internal storage. TWRP also has a file browser built in that might be useful.
I have tried uninstalling any Samsung drivers then using the SGS3 toolkit to install the official drivers, but that didn't change anything on the PC end.
Additionally, I tried finding my device while it was in recovery using ADB and there was no connection indication either.
I currently have CWM installed, but I didn't see a mounting option like I've seen for TWRP. Can I flash TWRP without a computer?
Or try this out: Download mode>Connect via USB>Let Windows download and update all drivers until the notification in the bottom right says it's ready to use>Unplug>Battery Pull>Boot normally>connect again. Voila! It works every time when it's being wonky and its a simple way that doesn't require a bunch of downloads!
installing insecure adb might help
Rebooting into download mode does nothing.
I believe rooting and installing CM10 means I already have insecure adb?
thanks
thanks
what next?
