Firstly, what rom are you running? Have you tried a different usb port on your computer? Ive run into this problem a few times, but usually if I plug into a different usb port it shows me the options.

Are you saying you don't get the pop up notification? If so just slide your notification bar down and change it from there...not too sure what you mean but hope that helps

[Q] My Galaxy Nexus is not charging or recognized in USB under any Windows edition

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!

Galaxy s2 will not connect to any pc

I just bought a galaxy s2 running stock gb on ebay and whenever I plug it in any pc it only charges. There is no usb notification nor does computer play a sound when the phone is connected. The phone makes a sound and just charges no matter what I do, I have tried usb debugging on/off and nothing. When I go into wifi/connection settings and select usb mode it says to connect a cable when the usb cable is already connected. I have tried many usb cables including the original samsung one.
Did I just buy a defective phone or am I missing something?

You need the drivers, either Google it or wait for someone to post a link, your call.

Try all usb ports as well! Even without the drivers you should still be able to use it as mass storage device

Are you using a data cable and not just a regular charging cable? You still see the option to connect mount the SD card evn without the drivers.

I'm not sure if this works on stock gb buy try going to settings/storage. Then press menu and if another settings option comes up then go there and see if there is an option to mount as mass storage device

Having the same issue, can it be that I am using a backed up ROM? I know that there are times when having a backed up ROM changes your system to R/O instead of R/W

MY PC basically does three quick beeps, like the ones it would make when connecting to the phone.... the only difference is when properly connected it would make one beep. I have 6 USB ports and have used all of them. In Root Explorer it states "Cannot detect SD card" that happened after i clicked on SD card to see what files were there.

I did a fresh flash of a ROM and now I am not having issues connecting to PC.

similar problem
I have the same problem of my gs2 not connecting to the computer. The only difference is that it isn't new, and I've been connecting to the computer using the exact same cord for a while.
I'm not really sure what the problem could be, it was working fine as recently as yesterday

Had the same issue I had to send it in for repairs USB port on the phone was effed up

Install moboro on ur PC, make sure developer options is enabled, and debugging is ticked, moboro will install needed drivers for phone to be seen, check to see if the phone is rooted y downloading root checker from play store, if it is rooted it may be an issue with the rom, try downloading Odin and putting the phone in download mode, Odin should see the device and say "added", if so go to sammobile.com find ur devices newest firmware and DL the file, use odin to flash the firmware on the phone, should solve all issue, u can also use Odin without being rooted too so, if u need more info, links or whatever, just let me know

WARNING
I had the same problem about a month ago. I had sent it to Samsung and they replaced the USB part of my phone. So if nothing works, DON'T PREFORM A FACTORY RESET IF YOU'RE ON STOCK! THAT CAN MAKE YOU STUCK ON A BOOT LOOP! but if you're lucky then everything will work fine. I only say this because it happened to me.

[Q] USB Debugging grayed out/disabled

I just bought a Sprint Optimus G today. The first thing I was going to do when I got it home was root it and investigate good ROMs. In the developer options, the check box for USB debugging is grayed out and I cannot select it. I have rooted android devices before. I'm running cyanogenmod on my Nexus 7. I had seen that people were able to root and unlock this phone which was the final thing that let me make up my mind to buy it. Any suggestions or am I just completely out of luck?

You cannot switch mode with the USB plugged in. Take the USB out and then switch to USB debugging

Hi here, I have the same issue with galaxy note 10.1 (android 4.4.2, not rooted) and I haven't found any solution so far. I have enabled developper tools, and the switch is green OK but even then, the "USB debugging" checkbox stays grayed out. I've tried with USB connected, not connected, I have reboot my tablet, nothing changes.
So I noticed that when the tablet is connected to the PC via USB, even if the PC does recoginses it (I can browse in the tablet's directories from the PC, the tablet never charges through USB, even at a low ratre or whatsoever.
But my main concern is with not being able to enable "USB begugging". Can anyone help here please ?

Device wont autorun or show when connected to PC.

The phone icon does not show when I connect to the PC, but I can safely eject from the hidden icons start menu and it does show as connected. The phone is also charging, but the autorun does not come up and I have no way of accessing the files on the phone to transfer.

NVM, found solution. Please ignore

What was the solution? Because I still have to same problem and even changed the charging port out, not fixing the problem. Along with changing the cable too.
