This problem exists due to drivers in your computer, It may not be due to CM10.,
Try to uninstall all drivers from "Device manager(show hidden)" whichever related to Mobile phone.

I found that problem related to some ROMs and was not because of drivers. Maybe some of 2nd boot ROMs is not a very good combination with the Green lens Defy.

hey guys,
I don't know if this still a problem with people. but I'm on win7 64bit and I can't seem to connect my nexus s, to my computer. I always have to upload from computer to dropbox then download the file from DB on my phone... usb plug doesn't work. I tried the same cable with my wifes Samsung vibrant and it recognizes it, but when i plug in my nexus s the debug icon shows up on my phones status bar for like 1 second and disappears. then window on my compter says "USB Device Not Recognized"
need help please.
What does it say in device manager (in windows)? Maybe the driver is wrong...

do u have a right drivers installed
have a look here and check Google USB Driver
I'm having the same problem. I have tried both my computers and multiple cables but I continue to get the error. When I try to update the drivers or reinstall them Windows says the drivers are up to date. I've tried every USB port on both computers as well.
I even took the phone into a repair place to see if perhaps the USB port on the phone was malfunctioning and they couldn't find anything wrong with it.

Try installing pdanet, I had a similar issue when I rooted my ns and installing the pdanet drivers solved the problem.

I've been having the problem also and none of the fixes worked. Not even PDA net. You'd think that the more people have this problem so one would have found a real fix by now.

I can't get the PDAnet drivers to install - during the installation process, my phone has to plugged in, which of course the installation program can't see.
Weird thing is if I remove the battery and then plug the usb in and start the phone, the drivers show up in the device manager but they always disappear before I can unlock the phone - appears the USB connection on my Nexus S is broken...can;t think of anything else.
Hello,
Update: For solution see my last two posts here.
today I installed the current nightly from here: http://defy.wdscript.fr/defy-cm9/
on my red lens defy (standard, not plus) along with the CM7 kernel.
Before I had CM7.1 on it. Now I cannot connect the phone via USB anymore. Nothing does happen. The settings are all correct (usb debugging enabled etc.).
Could someone recommend a CM9 build for the red lens defy which has working usb mass storage/debug ? I would rather not want to test 100 builds for working usb :S
Thanks in advance!

The USB has been working fine for me with Epsylon3's builds since.. as long as I can remember...
Does it charge via USB? i.e not in the computer?

It does charge via USB on PC and via USB on power adapter. This is not the problem. The problem is, that except charging nothing happens when I connect the phone to the PC. No notification where I could choose portals/mass storage etc.
No hardware popup under windows. On the PC I have Motorola drivers which were working fine with CM 7.1 just before.

check in /system/app if Usb.apk is present or not?

Yes it is there.
Should the same usb drivers that worked for 7.1 still work under 9.x?
Edit: I updated the motorola drivers and nothing changed.
Also @pk92:
Which build are you running, maybe USB just doesn't work in the most recent nightlies ?
Edit: Tried 3 nightlies now. Not a single one does work. Tried two different pc's too. Reinstalled motorola drivers on both. I'm clueless.
Edit 2: Also, if I disable USB debug and then reboot, it is enabled again.
Edit 3: I just enabled ADB over network as this is the feature I need the most. I did connect via ADB while the phone was plugged in to USB and right when it connected via wifi windows popped up a hardware dialog along the lines "Unknown device, installation failed."
Edit 19638746278: After reinstalling the motorola drivers once again and reflashing the latest nightly the phone does not even charge anymore via PC USB. Instead, I just get the hardware popup with "unknown device" which reports that it's "not working".
I wonder about the suspicious timing and also I wonder why it says "usb device not recognized" (freely translated from german)

I have the same issue - USB is dead (expect for charging)...
BUT: It worked yesterday evening and today morning, no idea what went wrong...
Same problem here.
All of the sudden it tries to install an MTP USB Device.
Which fails here.
For everyone with a RED LENSE defy (DON'T TRY WITH GREEN), here is a workaround:
Install the latest nightly for Defy PLUS along with the CM9 Kernel and reset battery stats. Nothing changes except USB does work again (at least for me).
Edit: see next post for MTP fix.
New post for clarity:
You then can fix the USB mass storage / MTP by following the instructions of the first post here:

connect with computer via USB
load Stock firmware files
click on "Flash"- / "Start" - Button (I can't remember how is called)
http://forum.xda-developers.com/showthread.php?t=1637966
You could use this tutorial..you'll find package with Samsung drivers etc..make sure you have uninstalled old drivers & rebooted before installing new ones.
Also make sure you have working USB cable etc.

Thanks for your help but my problem is when i connect my phone in download mode or regular mode the pc doesn't see my phone and my phone doesn't say any thing (like if he is not connected) i think not a driver issue because previously i connect the phone into ODIN but now after flushing the paranoid ROM this problem appear .

Your USB cable must be damaged or your USB port may need cleaning or damaged try these solutions http://forum.xda-developers.com/showpost.php?p=27205737&postcount=4571

If you have come from a GingerBread ROM that would be correct.
ICS/JB ROMS USE DIFFERENT DRIVERS
Now follow the advise and reinstall the samsung drivers and try again.

Turn off the phone, remove battery, wait 1 minute, put the battery back and restart the phone. Then connect the phone to your pc and see if that helped.

Every possible reason and solutions that I am aware of, for them are mentioned on that link , you have to try and test each one out, including various Drivers, for you to test...
BUT you keep saying there was no Sign of connection, which means the PC does not say anything (like unknown USB Device) or make a sound and your USB icon does not appear on the phone...am I correct???
That simply means there is NO link, which means, its either your USB cable or USB Port is damaged

Sorry nothing get petter still the problem
I'm running Eclipse ROM RC5.2 (JB 4.2.2).
I tried connecting my phone via USB to PC (not FASTBOOT AP, just regular) and I'm getting "Device not recognized". Do I have to download a different USB driver to work with my phone so I can transfer files?

Dumb question, have you tried other USB ports? For some reason, only 1 port on my laptop likes to play nice with my Razr M.
Also, do you have the default Moto drivers installed? If not, they are included in Matt's 1.20 utility download.

I did try a few ports (had the same experience as well). I may have uninstalled the moto drivers while trying to fix. I'll try the driver download.
However, the zip caused the phone to hang so I don't know what's up with that. I was connecting fine before CM10.1. Is that common when flashing ROMs?

Still no luck
I am running Eclipse 5.0-build-2 (build date 6/15/2013)
I have a nexus 7 as well and I ran into conflicts between the two drivers so I've had to switch back and forth with setups. However, after flashing eclipse the drivers no longer worked. I have tried wiping out all the USB vendors and drivers and setting the razr drivers back up again but no luck.
I'm going to try and use the drivers from matt's utility.

Reformat computer or try different computer
Assuming, you have no problem with your USB port, USB cable, installed latest LG USB Driver 4.0.4, running Windows 7 or 10...
We need more detailed info from your part to tackle this problem. Are you running on stock rom, kitkat or lollipop? Are your rooted and do you have TWRP recovery?
Then, you need to disable "USB debugging" from the "Developer options" menu. Then replug your USB cable and you can now select MTP instead of charging only mode. Good luck.

i have fought the no mtp problem and everytime i lost. if you try new things they just dont work. what has worked was to reformat computer then it will work..
I had the same problem with my G2. Unknown usb device, and the error was: "unable to get device descriptor" or something similar. Tried all software solution without success, so i have started to looking for hardware defect. I've changed the usb module, but no success. So, as a last chance, tried another mainboard. And "tadaaaa"... That was the problem. So, start to look for a working g2 with cracked screen, as i did.
