[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.
EDIT:

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.

Phone Charges but wont connect via USB

About 2 weeks ago my phone started having issues with the microSD card. I was plugging it into my computer off and on trying to get the card to read. Then one time the computer just stopped recognizing the phone. Since then I haven't been able to get any computer to recognize my phone. I plug it in and no MTP / PTP options show up, nothing in the system tray to indicate I have attached a new USB device. It just charges the phone.
Phone info:
Samsung SGH-i747m
Android version 4.2.2
Baseband version I747MUMLL1
Kernel Version 3.4.37-cyanogenmod-g7b457dc
What I've tried:
Uninstalled and reinstalled drivers
Every USB port on the box
Factory data reset--both from the setup menu, and the diagnostic bootup menu
USB debugging mode, both on and off.
Changing the UART and USB settings in the *#7284# PhoneUtil. After my last factory reset, it's set to PDA/MTP+ADB.
3 different computers, one Win 7 64 bit, one, one Win 7 32 bit, one Win XP SP3
about 5 different USB cords
I tried a touchwhiz rom CSROM
Cleaning the USB connector with a pin / air can
Changed the Kernal
Anything else I should try? Is there a way to determine if the USB plug on the phone is bad?

What ROM are you using? Not stock obviously running 4.2.2
Make sure fast charge isn't selected. You can't use USB with fast charge enabled. There is either quick tile setting for it (aokp) or under performance settings or in ktweaker.

Thanks for the reply. I've tried about 5 different roms, some touchwiz some not. Haven't gone back to stock yet though.
However I went back to a AOKP rom, Tasks650. Haven't been able to find the usb charge toggle button yet but I may have a kernal not compatible with it. However when I plug the phone into my computer and look at the Battery is says I'm on AC charge so that is likely a good place to start looking for a solution.
Thanks again.

If plugged into USB it says ac charge than fast charge is enabled. That's what it does. Goto setting and find the sub menu for the quick setting tiles. There will be one for fast charge. You select it, drag down your quick tiles and you can select and deselect it.

Faulty cord. Go on amazon or order another one. I use a heavy duty one from mediabridge for $5 and it does data and charging. Many times over the years I get an OEM micro usb cord that charges all 3 different galaxy S models I have then after use it will work on 2 and then only one. Sometimes it will just charge and not work with data transfer.
I highly doubt it's your phone.
I saw you tried different cords but were they new ? A picky microUSB or one that's more worn out might only work with a certain cord.
You can replace the microUSB port and it's cheap and I assume there a video on youtube for it but off course it's up to you.

Downloaded a new version of Task650 and enabled fast charge, reset the phone and then disabled it and reset the phone again. Same issue. PC does not recognize the phone but it charges. Check battery and says its on 'AC' charge. I wonder if somehow the two middle pins on the phone got shorted out so it permanently thinks its on AC charge?

Yeah, I just got 10 new microUSB cords to the house. They are cheap ones. However I tried a few other ones I have around the house. I don't know if any of them are the original Samsung cords but I certainly have original HTC microUSB cords. I've probably tried about 14 different ones in total now. I don't think its the cord.

I am in the same boat , my phone works perfect on Win 7 but not on Win XP.
I use airdroid or mmc adapter only if needed.
I did try a web link to fix the mtp issue ( before my xp pc was refomated ) and have had the phone recognized as a USB drive , can't find the link anymore. It has something to do with windows media player .
If I find something , I will report back.

On your windows XP device, download the newest version of Windows Media player. That always got it working for me.

I have this same issue now. Is WMP update really the issue here?

I've been having the exact same problem with my Note II - couldn't get my PC to recognise the SD card but it would charge.
However, then it stopped charging my phone, too. I naturally assumed it was the USB port or the lead, but having tried four different leads - all tested on my wife's SII and all working fine - I realised it was something else.
So I swapped in the spare battery I have and that did charge; swapped back to the old battery and that charged, too.
Weird...but OK, phone is working again.
Next day, no charging again.
Swapped batteries - no change.
Swapped batteries back - no change.
Reflashed ParanoidAndroid ROM - no change.
Flashed Samsung base ROM - no change.
Flashed ParanoidAndroid again - batteries start to charge on USB and on wall charger.
WTF????
Two days later (yesterday) - batteries no longer charge. I'm having to use an external battery charger that plugs into the walls (take the battery out of the phone, plug into the charger, leave to charge).
I've tried different kernels (Devil, NEAK), leads, batteries - nothing.
It's just goddamn weird - and a real pain. :crying:

Sounds like I would start with warranty for the batteries. Stranger things have happened because of batteries. On the inspire, when a battery would start going bad the phone would reboot when trying to take a photo with the flash on.

I Managed to fix the "Usb not detecting with PC when you connect it but only charges the phone. With me it was a software problem because it happened after i installed the new firmware. what i did was root my phone using Framaroot 1.4. its a apk application, then i installed Titanium Backup. went into titanium backup then to the MTP application and backed it up. then i restored it +all date,. plugged my phone in with the pc and it worked.

Mine turned out to be a software problem, too. I moved to the Beanstalk ROM and that fixed it, weirdly.
I've changed ROMs since (PACMan and SlimBean) and everything's still fine...

[Answer]
By default my phone was already set to the right settings for USB file transfers so I’ll assume most of these ship with the same configuration, Somehow it changed. I found this on a forum - it seems a few other folks declared it a success.
1.Launch the phone key pad on your note and press *#7284# (don’t forget to start with that * symbol!)
2.When you press the last pound sign (#) this will bring up an option that will allow you to change your USB connection settings (modem or PDA) – change it to PDA.
3.At the bottom there is a button that says Qualcomm USB. Click on it.
4.In that menu click on MTP + ADB option.
5.Save and reset.
6.Wait for your phone to restart.
7.Plug the micro USB cable to the Note 2 and the the other end to your PC or Mac
8.Let your computer down load and install drivers.
9.Once installing is done, unplug then replug phone.
10.There should be a USB symbol on your phone in the status bar - click on it. It should ask if you wsnd to use mtp or ptp. Click MTP
11.At this point your PC should open the phone’s folders in explorer.
12.You may have to repeat this process a few times....it worked for me after 4 tries.
Remember, you do not need to use Kies or root your phone for this to work and you should not have to fiddle with manually installing and downloading drivers in Windows 8, it should work no problem as is.
Good luck!

Phone isn't recognised by computer nor is my USB C stick

Hello,
I hope someone can help. I am trying to get my computer to recognise my phone. I am not rooted and I have Marshmellow 6.0.1
I unlocked developer options. I bought a cable and it worked! The computer saw my phone. However it stopped seeing my phone. Why I don't know! But when it did work I saw the driver was not for the 5x but from my S4. Well since it's not working I ordered the recommended USB cables by Benson Leung Tech Matte. Still unable to see my phone. Tried cables on another computer with same results. The computer I tried it on recognised my phone and then it also stopped seeing my phone.
I also bought a usb c stick to use on my phone. My phone responds to the stick but when I choose for MTP from charging nothing happens and i cannot access the USB Stick. In Dev options MTP is selected. I also noticed that USB tethering is not available. I have no clue what to try next.

USB debugging needs to be selected. Also, you need to toggle to PTP and back to MTP

Thanks for the drivers. USB Debugging is on. When I toggled Charging popped up instead of PTP and so I kept toggling and it finally went to PTP and so I toggled MTP and it goes back to charging! So I kept at it until it finally went to MTP. Is this normal? I counted 12 tries before changing from charging to PTP! But the computer doesn't see the phone. I did it a few times

i honestly never thought about this, is this even supposed to work without some kind of an OTG adapter. i mean sure, the plugs fit, put do the pins match/work for that configuration?
from how you describe that your phone reacts i would guess it doesn't, and it sounds more like your phone goes into client, as opposed to host mode.
very interested to see what someone with more knowledge of the matter would have to say about plugging a usb-c memory stick directly into your phone.

I've used several phones on my PC and at first it had a little trouble but finally settled in. Kind of like a new ROM. You have to give it a while to settle in and get its groove on.

not really a surprise there, but what OP described was putting a usb-C stick directly into the phone, without any cables or adapters in between, with the question emerging if that is even supposed to work (which in his case didn't) due to possible problems of the pin-layout, etc.

that does not explain his PC suddenly not recognizing his phone anymore though.
at this point it sounds to me like either there still is a driver issue (e.g. the mentioned S4 driver wan't properly uninstalled), or one of the usb ports (phone or pc) has an issue.
try different ports on your PC and make sure other devices work with the ports. if not try if you can get it to work by applying a little pressure in different directions to the cable and listen out for windows' annoying usb sound.
on the other end make sure your phone really is connected correctly to the cable. it should snap in just like the OEM charging cable which took some time getting used to to overcome the resistence of the usb-c port.

Thanks again for your quick reply,
I tried my Samsung Tab II tablet and my old S4 on my PC and they both work as advertised. Recognised right away and I hadn't used my tablet to my PC before. What I think is maybe its the USB on the phone itself?

not really a surprise there, but what OP described was putting a usb-C stick directly into the phone, without any cables or adapters in between, with the question emerging if that is even supposed to work (which in his case didn't) due to possible problems of the pin-layout, etc.
that does not explain his PC suddenly not recognizing his phone anymore though.
at this point it sounds to me like either there still is a driver issue (e.g. the mentioned S4 driver wan't properly uninstalled), or one of the usb ports (phone or pc) has an issue.
try different ports on your PC and make sure other devices work with the ports. if not try if you can get it to work by applying a little pressure in different directions to the cable and listen out for windows' annoying usb sound.
on the other end make sure your phone really is connected correctly to the cable. it should snap in just like the OEM charging cable which took some time getting used to to overcome the resistence of the usb-c port.

I think its the phone itself, since it did work briefly. Also with the USB C thumb drive the phone recognises it but will not read the thumb drive. I ordered it from play store I wonder how getting it repaired/looked at is going work Have to wait until Monday to call!

Hello again,
I Hope you guys like some feedback about my issue. Contacted Google and they asked me just about all the same questions and had me do some screen shots and try some of their ideas such as factory reset, trying other computers and other cables. Nothing worked so they sent me a new phone! Just got it yesterday. Would have been here sooner but I was busy!
So got new phone setup and the computer recognizes my phone on PTP but not MTP. Also my driver for the phone is a generic nexus and the it still shows up as a samsung! How can I get the new driver if when i do a search for new driver my computer says I have the best driver already installed? I don't want the driver to still be a problem. So i hope you guys have some answers. Lol! I know you guys do!!

If you had a samsung phone before you need to uninstall all the samsung drivers then install the proper nexus drivers

I was a little worried about uninstalling the driver but it worked!! Thanks! Now i can root it!!

7t No longer connects to pc via USB

Before you start in let me say that Im proficient in android and computers. When I use the red usb cable designed fot our 7t ( and any other cable) both my pcs fail to recognize both my 7t's. Fail to recognize as in no prompts, no nothing on the pc side for me to see at all. It only charges. The usb preferences are all greyed out, and even with the developer option usb debugging enabled they are still greyed out and nothing connects. My pc doesnt even see my android phone.
Are we having a software issue here?

You need to enable OTG under settings

No you don't, you can connect to your computer and toggle through all of the USB modes without touching the OTG service in settings. I have never had to enable it, I plug into a USB and I'm ready to do whatever I needed.
To the OP, sounds like your phone is having some kind of driver/communication issue since you have tried 2 separate computers to no avail. If you have done all of the easy troubleshooting such as restarting, clearing cache and stuff like that I would suggest backing up data and factory resetting the device. One suggestion I have for you before resorting to a reset is to reboot the phone into safe mode and try plugging it in once booted, I have heard of some random 3rd party apps and/or modules causing weird issues like this. If it works again in safe mode then I would delete all apps you installed that aren't mainstream i.e Facebook, instagram

USB C port not working

Hello All,
So long story short my 2018 model Pixel 2Xl suddenly stopped detecting my headphones nor it installed android driver when connected to PC. Ofcourse only good thing is it charges fine. Now since my phone warranty has expired I would like to try anything that could fix it. I already tried factory reset however of no help. So my question here is, is there any way I could install the driver binaries on my Pixel that could reset it? Now since my phone is not getting detected on PC except charging what option am I left with? Any way firmware change or reinstalling of drivers can be done through wifi or from within my internal storage? My mobile has stock firmware and it is not rooted as well. Any help is highly appreciated.

I had the exact same issue. Unable to plug into my PC and headphones not working. I used multiple laptops/desktops. All came back with the same Device Manager error stating that it was an "Unknown USB Device (Device Descriptor Request Failed). No matter what I would do it would continue to pop up on every single PC I plugged into. Tried different USB C cables as well. I was told a part of the board was fried.
I finally gave up and got a Pixel 4a 5g. I should mention I put in a new hard drive for my main PC and installed Windows. I plugged my Pixel 2 XL into my fresh install of Windows 10 and BOOM it started working again. I was able to unlock the bootloader and install a ROM as well. I just checked USB C headphone and they are working as well. I am not sure after testing so many variables why this was the resolution, but I am glad I found it.
I will note, in looking for the Device Manager error message I did find this.
Open your device manager. Click ‘View’ and then click ‘Show hidden devices’. Your Pixel 2 XL (or whatever phone you have) should be shown there and will be ‘greyed out’. Make sure your phone is unplugged, and then right mouse click on your Pixel 2 XL on your device manager and click ‘Uninstall device’.
Worth trying at the very least.

Great to know it worked for you. However for me I tried in my Windows PC as well as on my MAC and it doesn't work on both. Unfortunately my warranty as expired too so I have dropped an escalation to Google and awaiting response from their end. My Pixel 2 XL has never worked properly for more than 9 months from the date of purchase with USB C port already replaced once, screen replaced due to burn in, headphones replaced as it stopped worked etc. I have also heard many people informing about the port starting to work fine all of a sudden too. If Google provides free support well and good, if not will move to OnePlus maybe. Had enough of Pixel phones. I had the first version of Pixel XL and then bought this.

Use a sim ejector tool to pry out the dust and gunk from the type c port. Had issues with charging and usb connection, you may not be able to see it but there would be a lot of lint and dirt collected inside the port. cleaning it up fixes the issues.

Tried that too. There wasn't any dust as such but used a small paint brush to wipe inside throughly however didn't help. Any way to install the driver binaries via wifi or from within the phone rather than using a PC?

See my recent posts about my USB problems and replacing the internal USB ass'y. It didn't fix my similar problem though.
Cleaning the port is worth a shot. The SIM tool, a needle or plastic toothpick work great for this. I used a little alcohol too and the pad came out pretty dirty.
You can enable WiFi debugging/Wireless ADB in Developer Mode settings. You can then run commands in ADB. It won't let you unlock the bootloader with only WiFi though. That's what has me stuck.

I have the same problem and in my case the device has a sound bug that doesn't work at all, not even through the speaker, microphone or bluetooth. And the computer does not identify the cell phone or the device shows that storage option and only charges slowly. I don't know what to do help
