Every thing was fine while my nexus s istalled CM10.
But after I install CM10.1 M2,I lost my USB connection.
I get the following when the cable is connected: "USB device not recognized".
I tried on different computers and usb cables then got same "USB device not recognized".
After I google that, They said install an app called "USB Switcher". Open it and clicked change to mass storage
and reboot. Then my computer still said "USB device not recognized".
I found the cyanogenmod official forum. There was a man got same proble. I post my story.
but did not get reply.
I thought it may be a bug with MTP transfer mod.
But I did got more information about that.
I thought it may be a bug for CM10 ,but now I intalled CM10 MOD from CM10 M2 TO RC5. Still got same thing.
So I come here for help.
Thanks in advance for any suggestions.

Hi there
That did not help.
The problem happened after I upgraded CM10.1 CM2 from CM10.1 CM1.
What I did is that just wiped data,cache and install CM10.1 CM2. Then I lost USB connection.

i son't think it's rom related, i had the same issue with others rom, i asked here but nobody answered me... anyway i found that if you pullout battery then go in recovery fix permission and reboot it starts working again... i think it's some kind of error in the file system, propably the best solution would be to format the partition deleting all data on SD... i'm not able to understand what caused this, one thing i did, but i don't know if it's related, was using LAGFIX and trimming system and data... u can try to mount USB from recovery and see if that works, what recovery are you using ???

My recovery is ClockworkMod Recovery v6.0.3.1
I got a way from cm forum。 They said pullout the battery and hit power button random then it will work。But that didn·t help。
I tried your method fix permissions. reboot... IT`s did not work. I try to recheck the USB DEBUG MODE。 It's reboot ...
after all. Noting changed...
I will backup my phone. And try to repartition .and install the latest CM 10.1.0 http://get.cm/get/8Li .
that one is the last cwm recovery and usb mount doesn't work in that ... try last philz touch recovery u can find it here http://d-h.st/users/philz_touch/?fld_id=16784#files and try again, try mounting usb from recovery and see if it works, try flashing another kernel and fix permission againg, it may works the second or third time maybe ...
How to use this Philz Touch recovery?
Hi Kriout, I am unable to access my phone from my computer for about a week now. Earlier it was working fine. I tried resetting the usb ports by uninstalling and re-installing them. only once myphone (Nexus s I9020) is recognized as an unknown device but Windows 7 unable to update the drivers or find them for this device.
If I want to even go back to stock rom ( I am currently using Avatar ROM 4.2.2(android) ) as i am unable to access my phone via computer.
I tried going back to older updates of Avatar Rom to see if its the ROM which might be the issue, but that didn't work either.
I tried mounting the USB/SD via the bootloader but no use.
Can you help me please?

- you should first try to understand if it's a driver problem or a smartphone problem, try to mount USB on other pc
- if they doesn't work you should try to mount it in recovery, use TWRP, an old CWM ( in the last one this function doesn't work) or the philz recovery that u find here http://d-h.st/users/philz_touch/?fld_id=16784#files, try to fix permission, wipe cache and dalvik and pullout battery alos several time if it doesn't work. i found out that for me pulling out battery entering recovery fixing permission, shut down, pull out battery entering recovery and mounting USB often worked... you can try also using different kernel,
- my idea is that the problem is an error in the SD file system so propably the best solution could be formatting the unity from the smartphone itself. i still didn't do it but i made a good cleanup of all folder, even the system file and system folder, leaving jjust music photo and download...
- if everything works in recovery but not in the rom, it could be a kernel or a rom problem, so first change the kernel, if doesn't work make a clean install of something else ... i'm using MIUI v5 with marmite 8.7bigmem and for now everything started working again ...
Thanks

Here's what i Did. I did install Philz touch recovery. Its very useful. I also installed the Nexus Root Toolkit (NRT). Using NRT I launched the USBDeview. Using this i removed all the google related drivers from the system. I then restarted my phone is bootloader mode and restarted my system as well. Now my System was trying to install the nexus S drivers but unfortunately it said that the device in disconnected. But then in bootloader mode i put the phone in Mount USB storage mode and VOILA i was able to see all my files. I did take a quick back up . But still in the normal mode i was not getting the USB Storage prompt. Now i went back to the bootloader and did a factory reset. and then installed the Latest Avatar ROM. and now I am able to access the Phone storage through my computer.
I am not sure if i had deleted some files by mistake or some other issue. And thank for referring the Philz Touch Recovery. Its great.
Now am thinking of installing the Stock ROM for NEXUS S back on to my Phone. Do you think its a good Idea?
Thanks for all the help mate.

i don't think the stock rom is the best rom ... it depends on what you need ... by the way what is your data transfer rate ( into the SD )??? me in recovery get a good speed with a lot of spike, it transfer data at 5 mbs with spike of 15 and sometime go to 0 ... when i mount USB on the rom i get an almost constant 1.5 mbs that is reaaaaaaally slow ... if i test the write speed using the phone it returns me a normal speed...
p.s. when u say u mount USB in bootloader, u mean on recovery ?

Well, a little more information would be helpful..
But if you have a working custom recovery installed, your phone is far from being hard bricked.
Just get hold of an USB otg cable:
http://www.amazon.de/BIGtec-micro-B...e=UTF8&qid=1431587181&sr=8-1&keywords=USB+otg
All you have to do is download the ROM of your choice (must be compatible with your bootloader) and copy it onto an USB stick and than boot into recovery (hold power + volume down button > select recovery).
From here you can do all the necessary wipes, backups etc (please search through XDA forum, you' ll find all the info).
Mount your USB stick and copy/flash ROM..
Again do some more reading first - it's all there..
Good luck!

Try to using another USB cable or another USB port on your computer? It could be worth a shot.

Hi guys,
I was going to flash the stock firmware to my tab from the resurrection remix rom, so i went to the recovery (for some reason there was the cyanogenmod recovery and not the TWRP) and wiped everything with the system too.
I downloaded the stock rom and went to download mode and connected to odin and nothing happens... My PC , that i always used with odin and this tablet, now doesn't recognize my tablet, nothing, no notification or sound when i connect to it. I thought it was the cable though it worked for charging so i bought a replacement today but didn't work too... tryed to a different pc too ...
Now I'm stuck with a bricked tablet because there is no OS, with a ****ty recovery (the cyanogenmod one) and no computers detect the device by USB...
Is there something that I can do to save this tablet?

I have put the rom on sd card and twrp too but there isn't an option to install it, i mean there is only adb sideload (that doesn't work because can't connect to pc) and apply update that looks only in /data/media path and it doesn't let me go to the sd card

Bro thank you very much for your help, at the end I tried buying a 3rd cable that worked it was a cable problem. At the beginning i bought a chinese 2€ aftermarket cable that probably only had connections for charging, later I bought a new cable from amazon that I got today and worked like a charm when i put in the computer )))))

This forum's header is "General Questions and Answers" and you got a well-meant answer by me. You should have asked for help in forum "Android Q&A, Help & Troubleshooting", IMO.

Can you still boot into TWRP?
Can you still boot into the ROM that you had installed?
When you say you can't see your sdcard in TWRP, do you mean that you can't see internal sdcard or that you can't see external sdcard?
I'm pretty familiar with the S2 so I can probably help you if it is solvable.

Have you gone to "Mount" in the main menu of TWRP and mounted your SD card? I believe it will be called USB-OTG. After that, go to "Install" and tap "Change Storage Device" and select "USB-OTG".
Disclaimer: I haven't messed with the S2 in a very long time, so my apologies if I'm incorrect.

Can you still boot into TWRP? Can you connect to adb while in TWRP? If you can get adb connected while in TWRP, try using adb commands to push your ROM file to internal storage, TWRP should see it then.
