[Q] Galaxy nexus USB data stopped working (still charges)

My Nexus is stock but it is unlocked.
I have the latest CWM on there (touch 5.8.0.2)
I was currently downloading all the necessary stuff to flash to AOKP but havent even got there yet because all of the sudden my USB isn't working.
I have tried two different cables, the stock one and a different one (both which were working before).
I get charging working through USB but no file transfer.
I just did a wipe data/factory reset and wipe cache via Recovery, and still nada.
Am I cooked here? B-stock with no warranty from Expansys, now currently kicking myself for not buying brand new.
[edit] yes MTP and USB Debug were/are both checked on
[edit2] a lot of my searches seem to indicate that you can move and transfer via adb in recovery or fastboot while having this error. I am not finding that to be the case.
[edit3] windows 7 does not show any indication of a usb drive or anything plugged in as it used to before. This is obviously making it hard for me to try things like reinstalling drivers and whatnot.
thanks

It probably has nothing to do with the USB port...
Plug your phone into your computer, and then scroll the status bar down. You should see a notification "Connected as xx" Select that, then make sure connect as MTP is checked, if it's connected via ptp (camera) it won't allow you to sync files, for what reason so ever...
If that doesn't help, then reflash stock ROM, that usually helps.. With most problems anyway...
If both of these don't work, then I'm sorry, but I can't help you. I'd then call Samsung, and send it in...

Yea MTP was already checked on. USB debugging being on would have auto kicked in as well.
I flashed AOKP but still the same issues. The hardware might have gotten bonked - I hate how fragile these tiny little ports are!
Is there some kind of diagnostic I can run to see if it is truly a hardware issue?

It's the kernel, try another one

Just swapped to Faux kernel... still persists.
I'm really starting to think its the hardware but crossing my fingers there's a fix.

the same thing is happening to me, it started yesterday too!
I am on AOKP b-23, Faux kernel....
plug in my usb, it can charge but absolutely nothing happens on the computer side, try it on number of computers too... but the phone is able to charge.

Mine started doing this. Would charge‚ but sometime I couldn't transfer data or use adb. It seems that the USB didn't like to stay in my computer. Any little movement would unplug it just enough to keep it charging but nothing else.

I've since tested the MHL cable and also tried using the usb host cable to connect a mouse and both work... does that mean my data connection theoretically could be fine?

I'm using AOKP #23 with Trinity and not had this issue at all. Whether it's because I combine the ROM, Gapps and kernel before flashing I don't know but my phone is running fine

im having this problem as well. does anyone have a solution?

So all you guys that are having problems have enabled MTP through Settings >Storage?

Had this same issue yesterday ( phone was 1 day old ) had it plugged into my windows 7 machine and all of sudden the machine couldnt see it. So I wiggled the cable sure enough the computer saw it, jiggled it again and it would lose connection to the PC. Tried this on several PCs with Several cables and same result everytime. If I held the cable connected to the phone at the right angle it would never lose connection.
Ran to Verizon and the numbskull behind counter tried telling me that is normal and I would just have live with it, almost punched him in the throat. Demaded he go get another phone and show me if that one does it. It didnt so he swapped it and was to hasty about it, ended up giving me another cable charger and headphones WOOT WOOT
new phone doesnt do it as of this writing

See http://forum.xda-developers.com/showthread.php?t=1427539 This is probably the issue you guys are experiencing. Seems like you should swap it in or try to fix it yourself by changing the USB charging board.

i'm an android dev and this has happened to me. really really not good to no longer have adb access to my device. restarted both the phone and computer and tried a different coworker's computer and usb cable with no luck.
i used a samsung usb charger last night which i usually never do (i usually just charge it on the computer) and now this morning i have no data connection.

Hello,
have this problem already on my GNEX. After some reading, i got an idea to turn off Fast Charge in Trickster MOD.
And MTP now working .
Anyway there is an warning about fast charge - " Enabling this will disable access to phone storage" .
Problem solved

Yes, i can't connect mtp too and you rigth..usb fast charging is the problem.

Just so y'all know...Fast Charge is simply tricking your phone into thinking it's plugged into an AC outlet...rather than a USB port.
Thus MTP won't work.

same issue here
I'm having the same issue here. Charging works fine with 2 computers and multiple USB cables (as well as AC and car charger adapters), but data transfer has completely stopped working. My computer won't see my phone at all. I have the correct drivers (given that I used them to connect to my computer when I first rooted and unlocked the bootloader). Tried changing the drivers, but I can't get my phone to show up in Device Manager at all. MTP and USB Debugging are enabled.
The only thing I can think of is that I dropped my phone while it was connected, and now the USB cable only charges the phone if I bend it in a certain way (it usually requires upward pressure where the cable plugs into the phone to work). However, other USB charging cables work just fine without any pressure. Is there any chance that a new OEM Samsung USB cable might solve my problem? The other cables I've used weren't OEM.
I normally use a wi-fi data transfer app because the USB data transfer has been slow since day one, so that can be worked around. What IS a major problem for me is that I'm trying to re-root my phone after my root access was lost with the 4.0.4 OTA update. I didn't keep up with the news and only realized last week that my root access had been lost because I tried to do things that required root. Since the OTA update trashed my CWM recovery image, I seem to have no way to re-root and reinstall CWM aside from going back to my computer and doing what I did the first time. But if I can't connect to my computer, I can't do that. It also seems that I would need computer access to remove root in case I bring it back to Verizon for a replacement under warranty.
So on another note, if you guys know of a way to re-root my phone without connecting it to my PC, I'm all ears...

I have run into a lot of USB defects on the phones I have received. It might be wise to get Samsung to repair it, but you will be without a phone for a week. You could also try another cable.
I used to have similar issues except where the power got routed into the data port, frying my phone in multiple areas.
On Samsung's repair ticket they said REPLACED COMPONENT (I'm assuming this is the usb controller and port) this could be the solution but it requires sending it in.

Computer not recognizing Note 2

Has anyone had a problem with this? The only way for me is to go into recovery and mount it. It's connected as a media device.
Thanks in advance!

Sounds silly, but did you try rebooting your computer? I had to do this the other day when mine wasn't recognizing my phone. Rebooted computer, worked fine after.

Samung's drivers are awful. I had to install, reboot, remove, reboot ad nauseum until I finally got the drivers to work. I also found I had to connect the phone then wait a few minutes before the computer would acknowledge the phone.

specteA 187,
I've only ever had the issue if I've tried USB ports on the front of my machine. For some reason those ports can be a bit flaky.
Plugging USB into the back of my machine causes no issues. Weird.

For me, on Windows 8, I have to switch from MTP to PTP, and then back to MTP for it to mount. It sure is wonky.

Yup I tried everything. The only way that works perfectly is to mount the drives via recovery.

My phone doesn't even try to get into mtp mode :/

I found that if my computer doesn't recognize my phone, I put my phone into download mode then reboot back to normal and the computer will recognize it. Kind of a pain to have to reboot 2x but seems to work for me.

I've had 5 Samsung smartphones (Captivate, Infuse, GS2, SkyrocketGS2, and now the SGNote2) andI use an XPSP3 desktop computer and have never had any issues with computer recognizing phone until the Note2. Odin3 works like a champ on the Note2... it's the plug-n-play recognition for transferring files back and forth that's problematic. Yes, I've uninstalled/reinstalled drivers, Kies, etc, used back ports vs front port... I think it has to do with the MTP file transfer protocol now used. Here's what works for me with the Note2 and the PC:
Connect phone to PC... phone's "USB PC Connection" box opens and you have 2 options: MTP(media/files) or PTP (camera). If PC doesn't immediately recognize device, I do one of two things which always works:
1. toggle between MTP and PTP a few times... if that doesn't work,
2. unplug usb from PC port and reinsert (either same port or another)
Windows Explorer will then recognize device and add "SAMSUNG-SGH-I317" under "My Computer" and list it under "Other" devices in panel.

I had this same problem today on my new N2. Drivers would not install. All I wanted to do was to drag my pics and music onto my SD card. I worked around this of course by removing the SD card from the Note and putting it in the adapter and doing it that way. I still haven't gotten my drivers to install. I may just get the drivers off the Internet

+1, my ONLY complaint about this phone.
I gave up trying to find a fix after installing/un-installing/re-installing drivers/kies/odin3 about a bazillion times and only getting it to work a random few times.
Not even worth the effort...
Dropbox is my best alternative. Sure sux tho...

Thanks, Should've mentioned that I've tried all of the above methods. It may be that, since I work on so many Android devices, my pc is just too full of incompatible drivers and I've yet to clear them properly. Even If i did I'm fairly certain that I'll be working on more devices and will screw it up all over again. My network is pretty quick and Dropbox/esFile Explorer is convenient so I really shouldn't complain.

[Q] Mac won't recognize Galaxy Nexus

I've read a couple places that Mac 10.8 won't recognize the Galaxy Nexus. Is this true? USB debugging is enabled, my phone charges when connected to the Mac but Android File Transfer doesn't recognize the device, nor does it show up in the status bar. I've been using DropBox which takes forever but it's the only answer I've found.
Thanks for your help....

It's really strange, my macbook pro recognize my gnex without any problem. Maybe do you have fast charge enabled?

Dang....it's not set to fast charge, at least that's what my ROM is telling me. Are there various places to check and see if it's fast charging? My old Mac worked fine so I don't know what the problem is but it sucks

And if you run in terminal an adb/fastboot command, when the daemon's started does it recognize the device?

I know how to get to the terminal....can you explain the rest?

Try disconnecting your USB cable first. Wake your phone from the lock screen and connect the USB cable again. Should be recognized by Android File Transfer. Try to keep the phone from sleeping by setting the display option to sleep only after 10 minutes (or whatever you want). For some weird reason, the phone has to be awake for the macbook to recognize the device (in my case). I hope this solves your problem :fingers-crossed:

Same happened to me. Try unchecking usb debugging and then plug in usb. Should work.

Well, maybe the two way above are easyer and could help, try with them. However it's a strange behavior, my gnex it's recognize even if it's in stand-by and with adb debug active!

This is so frustrating.....no luck.

Issues accessing in Windows Explorer

Hi guys,
All of a sudden I can't get access to my GNex which I'm running official, un-rooted Google Jellybean 4.2.whatever
When I plug the phone in USB I get the Galaxy Nexus in my explorer, when I open it I get the "Internal Storage." I open that up but then all the folders just keep loading in apparently, and the progress bar at the top just keeps going forever and ever. If I try to access any of the folders then Windows Explorer hangs completely until I unplug the phone.
I've tried turning on/off the USB debugging, I've tried turning switching between MTP and PTP and unplugging/replugging in the phone but nothing seems to work.
This all worked perfectly fine until recently and I have no freakin idea why.
I've got the drivers installed (the ones necessary to use the GNex Toolkit because I used that to wipe my phone completely and use an official ROM.
I can access everything just fine on the phone itself with a file explorer app so I don't believe it to be a memory corruption thing or something like that.
Here's a pic of what I mean.
http://i.imgur.com/6C63Yk0.png
You can see the bar at the top, you can see some named folders and some unnamed folders. If I try to access any of them it just hangs.
If I leave it to run and progress through the bar just keeps going forever, it doesn't stop and I still can't access any of the folders.
Any ideas?

Do you connect your phone via USB hub or anything similar?
If you do try to put your phone directly to USB.
If you have Logitech unifiying reciever try to unplug it and without it. That was a problem couple of times for me.
I am having problem with phone constantly disconnecting from USB in Explorer, don`t know why. MTP is such a bad solution, using AirDroid most of the times

It's not plugged in a USB hub at all. It goes right into my PC with a USB cable that I've always used so it's really weird that this is happening now.
What's airdroid? I'll have to look into that, thanks.

Note 4 developer version not connecting to PC as drive

I have a rooted Note 4 developer device and when I connect it to my PC it does not appear as a drive. I'm using the USB charging cable that came with the phone. If I connect with my Note 2, that works, but not the Note 4. I was able to use Odin to flash TWRP so the PC saw the phone and used it correctly. When I click on the USB safely remove hardware and eject media icon in my taskbar, I get an Eject Samsung Media option, so it sees the phone. Maybe my modem is set to an alternative mode? I have no idea how to change that.
The SD card works, and if I want to copy files to and from that I remove it from the phone and put it in a card reader and transfer files that way. When I check the drivers in device manager on the PC everything looks like it's working fine, no yellow triangles with an exclamation mark. I have USB debugging turned on. Maybe it's a setting in TWRP? I am completely baffled and would greatly appreciate any ideas or solutions. And yes, I've turned the phone off and on again...

I've had this problem before and I uninstalled the Samsung drivers and reinstalled them. Drivers can be "finicky" on some versions of Windows. Make sure you get the latest drivers from the Samsung web site, not another download site. I'm sure you know this, but make sure USB Debugging is selected and you connect as a Media Device under USB connection settings. Hope this helps.

Thank you for your suggestion, JPCalhoun. I reinstalled the drivers, but still no luck. The computer's USB charges the phone. The PC, which is a Windows 7 64 bit machine, sees the phone as a Samnsung mobile USB CDC composite Device. On the phone, the little UBS symbol just never appears. I think it might have to do with the modem settings on the Note 4. I just have no idea on how to access them. I know on older notes you would bring up the keypad and dial in a certain number to access the phone's modem. I don't know what the number is on the Note 4. It's weird, everything else works perfectly on the phone, just not the USB settings. I'm going to try and transfer stuff wirelesslly. I transfered all my old contact information from my old Note 2 to the Note 4 wirelessly, so maybe I'm just stuck going that route.

That did the trick, Manbat. I thank you profusely! I got a Note 4 dev edition and you would think that they would have had the USB setting set to MTP+ADB. Anyway, now she's rooted and working well in my ColorCross VR headset. Running Crysis 2 in Stereo 3D with this display is mindblowing. Better resolution than a genuine Oculus Rift DK2 headset. And no tether! Good times. Thank you again, Manbat!

Yea I had that same exact problem yesterday, I am pretty sure its because they took a regular retial, unlocked the bootloader and left it in that setting. It was driving me nuts but I found it by doing some research, when I suspected the problem, i didn't know how to get into the hidden menu until I found that app man what a pain in the ass
