First of all, I have searched everywhere in the forums (in all sections) outside the forms in all means to find anybody with the exact symptoms that is happening to my galaxy nexus but to no avail
There are many cases where others has faced issues but not as unique as this one.
PC = Windows 7 (64bit) + Windows 7 (32bit) + Windows Vista + MAC OSX + Windows XP(32bit) .. etc
I have been seeing all the issues (common or unique) with charging and USB in GNex but mine is truly a unique one.
I got this phone 2 days ago on stock 4.0.2 locked/unrooted from a Blondie.
The issue is when connecting the USB via PC in Android mode (while inside the OS)! Thephone doesn’t event register in windows (i.e. not connection sound or anything shows up in the system trey or device manager)
The phone doesn’t charge as well when it’s ON (in Android Mode) and connected to the PC.
In simple and bare words .. there is no spark!? it’s as there is no physical action happened in the PC nor the Phone?
Here are facts that might ring a bell to figure out what’s going wrong here:
The phone charges normally via AC (stock charger or other chargers) and there is no issue at all in both cases wither the phone is switched ON or OFF.
Fastboot is properly connected and recognized in windows and the phone gets recognized when connected in ODIN as well and I am able to flash (already did a couple of stock rom flashing using Galaxy Nexus ToolKit v5.6
It also worth mentioning that when the phone is OFF and connected to PC via USB it shows the bolt icon and start charging for 5 seconds and reboots again to the bolt icon and this gets repeated endlessly.
I have also tried 4 different Micro-USB cables just to be fair.
Because of this, I am unable to root the phone and this is driving me crazy!
Please help me out here.
Did you download the samsung drivers?

It could be an issue with the micro-USB port on the phone. Some people have started having issues after a few months, myself included. If that's the case you have to get it serviced.
Songs like an issue with your drivers.

I don't see the point!? The device is not even picking up when connected to the PC? I don't reach to the point of driver installation unless I'm in fastboot or Odin.

Go to the samsung website and download the drivers onto your PC...if you don't have the drivers it can't possibly connect to your phone to charge

Ok, will go ahead and try the official driver installation (I have downloaded the driver form http://www.samsung.com/us/support/owners/product/SCH-I515MSAVZW
EDIT: I have installed the drivers in both Windows XP and Windows 7. Still facing the same issue!?

i found out that if i plug in the usb to phone phone, then rebooted it. it would get recognized.
Is the microUSB port really so delicate on the GNex?
I had an Xperia X10i before this and had to replace it after nine months.
Should I be extra careful?

Drivers won't fix your problem.
Will the cord you are using charge the Galaxy Nexus if you put it into a wall charger?

Yes, it perfectly charges from AC using thew same cord.
For a temporary solution, you can use an app called software data cable, which allows you to access the file system using ftp. Or any app that does this for the matter.

The only thing I can think of is you either have a defective phone, a defective USB port, or you are trying to use a low power port.
I just plugged mine into a desktop that doesn't have a Nexus driver and it worked fine.

I would say it's a defective USB port if fastboot/ODIN are not functioning. but both modes are working flawlessly and I always keep flashing stock roms!? such a weird issue!!!?
Low power port? Nope! I have USB 3.0 and 2.0!
Hi,
the USB port of my GN does not work for data.
If I connect it to the charges, it's getting charged as usual.
But if I connect the phone to my PC (Win8 or Linux) it doesn't work. Only the charging function works.
The PC tries to install the drivers for a new USB device but after a short time it says that it couldn't be installed.
Anyone who knows a solution?
Since you mentioned this I went ahead and tried my Rooted GNex on PC and Mac. It worked fine on PC but MAC is not finding my phone.

Have tried a different SD card?!? or might a different USB cable solve the issue..
Sent from my Wildfire S using Tapatalk 2
I'm not using the original SD Card, but a 8Gb one I bought for 15 euros. It's class 10, and as far as the USB Cable goes, i've done what you've suggested, but had no success
Check for loose usb port... generally this happens when a usb port is loose.
Try inserting it in different port as well and also i'd like you to watch for dust in both ports (Phone as well as USB)

I have a demo Galaxy Note 2, which is running on the Revolution HD 8.0 rom. I flashed the following PIT file;
PIT_N7100_16GB_20121102.pit
The device works perfectly; very smooth, no FC's, the full 10.16GB of system space etc etc. However, one issue I am having is getting USB OTG to work.
When I plug in any one of my 4 USB OTG cables, I get the following;
'USB Mass storage connected'
'USB mass storage unexpectedly removed'
Does anyone have any ideas why this might be happening? I was hoping to use my Note 2 as a portable media viewer for the photos/videos I take on my DSLR. Kind of frustrating ...
Does your device do this at all? Better still, if you have a demo version of the Note 2, does USB OTG work on your device?
Really hope someone can help,
Thanks
There is a fix for that in custom roms try wanam rom 2.8.
I think you may find the flashable mod somewhere in GS2 forum.
Good luck

Your charging port seems to be loose. You may have to change it.

USB OTG works on my device but...
Without a power source I can only see USB sticks and SDCards.
If my hard drive enclosures have an external power source that I hook them up to, then they work too. It the drive is NTFS formated then you have to use Paragon exFAT, NTFS & HFS+ to see it.
Thanks very much for taking the time to reply. I actually ordered and replaced the usb connection port, yet the issue still remains. So I am quite sure it isn't a hardware fault. I'll try and find the mod you have mentioned ...
Just out of curiosity, is there anything else I can flash beyond the pit file, the kernel and the rom? My device is a 'demo' Note 2, so I am starting to think that maybe Samsung put some other firmware file on the device that tells it not to fully mount USB OTG devices (it'd make sense to do such a thing in order to stop customers in a shop loading up their software from a USB stick).

Sir, how did you get a demo version of note 2? Do samsung sell them to? Lower price? Im interested.
Sent from my GT-N7100 using Tapatalk HD
I bought it from a guy who was winding up his mobile phone shop business. He had 4 of these things. The mobile phone component doesn't work - but everything else does (apart from USB OTG on my device - v.v.frustrating!).
You can find them on Ebay by searching for N7100x or N7100 demo version.
If anyone else has a N7100x, please tell me if your USB OTG works.The Wanam rom fix is for wakelocks caused by disconnecting a USB OTG device --
My Note 2 doesn't mount USB devices fully in the first place...I'll keep searching in the hope of finding a solution

I've tried everything I can think of to get this problem sorted. I am starting to think that it is a hardware issue relating to the fact that the 3G aerial that would normally be powered/connected to the USB connector board is not attached.
As such, the USB power being delivered to USB OTG devices is higher than normal (given that there is no 3G power drain)...so it perhaps overloads and disconnects connected devices.
I have replaced the USB connector board with a hardware revision 0.2 board (the one that came with the phone was a 0.7). I have installed the following files via Odin;
BOOTLOADER_N7100XXDLJ2_422394_REV00_user_low_ship.tar.md5
CODE_N7100XXDLJ2_422394_REV00_user_low_ship.tar.md5
CSC_XEF_N7100OXADLJ2_422394_REV00_user_low_ship.tar.md5
MODEM_N7100XXDLJ2_422394_REV00_user_low_ship.tar.md5
t03g_0907.pit
I don't think there are any other software partitions on the phone that can be overwritten (the phone is therefore 'stock' as far as could possibly be the case with a demo phone).
If you do find a solution, I would be most grateful to hear about it. This is my perfect device for video/picture editing & uploading to Youtube whilst cycle touring (I don't need the phone connectivity when abroad). Although I can work around the USB OTG limitation, it would be incredibly useful to have that functionality.
All the best,
Laurence
me to.. stil looking for this solution. When OTG pluged to my phone, it's rapidly connect-disconnect in 2 seconds x_x
ROM : hawkish extreem 4.1.2
Kernel : Stock
I have another issue. When i plug OTG cable, I can use flash disc and everything is OK. But then, when i unplug and plug in charger, charging doesn't start. I have to reboot phone, and then charges...
Is this normal?

So any one found solution? It's very important function for me in my work.

solution is very simple
go to Play Store
search USB mass storage
or the app name (USB mode switch for SGS1 on CM) by Zatta
then install the app
problem solved

Maybe try over n over again it takes me like 10 tries so my computer can recognize it

I have the same issue. The most reliable way I find is to remove all drivers for the phone from the PC. Connect it, and just let Windows install part of the drivers. It will not install the Samsung drivers, but will connect reliably via USB. I did on thread a while back on it: linky. It's a limited solution because of the lack of Samsung drivers, there is no ADB access.
There is some issue with the Samsung drivers not have the correct hardware reference or something. I think it's tied into Kies, but I've had Kies installed and still had issue. Plus, since Google changed how the storage is organized to allow for difference user profiles, the phone does not work like normal USB thumb drive anymore. I use it to store school projects, and I have to copy and paste them from the phone to the PC and vice versa; not all files require this. Some are can be accessed while stored on the phone on the PC.
I can almost guarantee you're using Windows 8 .... and it has something to do with the driver signature stuff
