Hi all. Long time lurker, first time poster here.
I have had my Galaxy Nexus for around a year now and have never had any problems - I've flashed countless ROMs and kernels, etc. However, just recently my phone has stopped being recognized by my computer(s). I've searched and searched and read every thread remotely related to the problem and still the problem persists.
At first I thought it was the new Macbook I was using, or OSX, but I've tried everything I can think of in Windows, OSX, and Linux.
When plugged in, I get nothing in OSX - finder won't find it, android file transfer won't find it, adb won't find it. In Windows, I get an unknown device in device manager, and a popup on the toolbar saying the device has malfunctioned. I've tried all three driver installs with Wug's toolkit, switching from MTP to PTP, turning Debugging on and off, flashing new roms and kernels, installing drivers manually, installing drivers through the Android SDK, even different computers - but every time I get "The USB Device has malfunctioned," or nothing at all in OSX's case. I've even tried a laptop running Ubuntu - still a no go. All the while the phone shows it is charging fine, but no indication of being connected to a PC like it used to do.
I've even tried bending the USB port a little as I've read in some guides and cleaning out the port - no luck. I have yet to try a different cable - one is on the way - but my next step is to replace the USB port board myself, unless anyone has ANY ideas.
It charges fine and never has any problems, it's just I cannot get it to be recognized by anything I plug it into.
I don't have an option to enable/disable fast charge in this ROM (currently on CM10) but I have disabled it in one of the ROMs I flashed to and still no luck.
Is there anything I've yet to try, besides using a different cable? Maybe fast charge was enabled in another kernel and it's screwed up some stuff? Although that seems impossible because I've factory reset/wiped everything and flashed different ROMs and kernels and still nothing. I just don't know at this point.
Any input at all would be great, but I understand if there's nothing else I can do besides trying a new cable and then replacing the board. I finally get going in Android development and this brick wall stops me in my tracks.
Thanks guys.
Try to clean the port (by blowing all the dust out of the usb-port)
For now, just use 'Wifi-explorer'. I use it ALOT just to save my USB-port
The two options you came up with yourself sounds most plausible. I've been through a ton of MiniUSB cables that have gone bad out of nowhere (just lying in my briefcase). So test that one first before buying a new USB port.
Well what do you know, it was the USB cable. I cannot fathom how a USB cable just stops working on the data side of things but still charges after just sitting around. I found another cable in a drawer, plugged it in, and voila, everything's working. Glad I don't have to replace anything, though. Woo!
Good thing is though I now know my way around the drivers and the SDK and am pretty sure I could write a guide on everything you could do to fix a USB issue. The more you know!

I had been using AirDroid before and loved it. And even though it was a cable problem, I know know my USB port is squeaky clean, ha.

I've scoured the forum to an answer to my problem but I've not yet found any so hopefully you guys can help.
Somehow I managed to soft-brick my Epic 4g, just been having all sorts of problems. Anyway I'm able to get in download mode just fine so I should be able to restore my phone no problem right? Wrong.
The problem I'm having is that my computer won't freaking recognize my phone when it's plugged in. Here's what I'm doing:
1) Start Odin, have phone ready in Download Mode
2) Load up the PDA file
3) Plug USB cord in to Phone
Once I plug the cord in to the phone my computer says that it does not recognize the device (or that it's malfunctioned or some such thing).
I've tried everything to fix this! Here's a weird bit of success though:
This morning I turned on my phone, did the 3-button combo to get to clockwork recovery then plugged my phone in. The phone was recognized!! I rebooted, went to download mode and Odin recognized it! At this point I tried flashing my stock kernel and it failed. Now I'm no longer able to get in to recovery using the 3 button combo and my computer no longer recognizes my USB connection again in download mode.
Am I totally screwed here? What's up with the USB??
OH! Just wanted to add: I'm using Windows 7 x64 and I do have the correct USB drivers installed.
hmmm
Have u tried redownloading the samsung drivers? They really ***** out sometimes...
I have. I've actually gone through and tried the x86 and x64 drivers listed on the forums as well as the official samsung drivers.
Usually when Windows says the device is unrecognized or has malfunctioned it has to do with the USB port you're using not having enough power. The stock Epic USB cable also sucks because its long and skinny which leads to more power drop. Try using a better quality USB cable (I always use a blackberry cable when flashing) and connect it to a USB port on the back panel of the computer that comes directly off of the motherboard.
Some USB ports may work better than others - for instance on my Dell E series laptops I can't flash when using the USB ports on the left side of the machine, but the ones on the right work perfectly. The left side ones just don't deliver as much juice and this phone is a power hungry little guy.
Alright I got it working. I do think it had something to do with the cable. I kept swtiching back and forth between Samsungs and my old Motorola one. After a few reboots and reinstalls of drivers the Motorola one finally worked
I have had that same thing happen, tried an old moment cable and problem solved. After that went on ebay and bought some extras just to have on hand just in case. Also thanks about the usb port explanation, makes sense.

Hello all. I'm TK, newb who has been lurking for a while. The forum has led me to some awesome changes with my Evo, but that may be catching up with me. I'm still rooted and running CM 7 with SZ 1.01, and none of my computers are able to recognize the USB drive on my phone, regardless of which cable I use.
I can't get ADB to work on my PC, so I'm not able to perform any commands for the phone.
Can anyone help me with this issue? It would be much appreciated. Thanks!
Do you have debugging(in application settings) on when trying to use adb? What about allow mock locations? Try turning debugging off and then turn it back on(while plugged in USB). If that doesn't work you could always go to recovery mode and enable USB toggle and get it connected that way. Also make sure you're actually pulling down the notification bar and selecting "mount".

Does your phone get recognized at all on your computer when you plug it in? If not you may have a hardware problem -> usb port is loose.
On my original cord that came with the phone I had to trim off about 2 centimeters off of the plastic to go in far enough to have my Toshiba laptop to read it. I have had to do the same thing to several cords since. Maybe your usb?

Yes, my computer just says that it doesn't recognize the hardware. it charges just fine by the computer.
I'm running ClockworkMod for my recovery, I'll check for USB Toggle there.
No joy on finding USB Toggle.
It's called something different. Can't remember but it's there, I believe. I've only been in Clockwork recovery like once.
Hey guys!
Last night i installed B30 of AOKP to my phone via CWM and now my phone will not mount to my computer. I cannot install a different rom as i cannot place it on my intSD. Has anyone suffered this problem and/or has a solution?
Thanks for your time,
Steve
Are you using fast USB charge?
Sent from my francoPhone
I'm not no. Or i haven't enabled it. Where would i find it?
Thanks for the quick reply btw.
No it's not
What kind of computer? Windows,its a driver thing, if its Mac u need android file transfer which is a nifty application u can find for free.
Edit: Try a different USB slot btw

I have the same issue. MTP is selected, but I don't get any signal from windows that a USB device is connected. It's like plugging it in the usb wall charger, all it does is charge it. If it is the fast charge usb, how do you disable it?

Ok, the Galaxy S II looks to have the same issue.

I noticed this problem when I had fast charge enabled on this rom.. I rectified the issue by disabling the fast charge present in AOKP B30..
Navigate to Rom control and click performance tweaks. You should see a checkbox to disable fast charge there.
Restart your phone after disabling it for the changes to take effect..
After disabling and rebooting your phone, the usb should mount to your computer properly..

Well the mtp fixed it. Guess I should have looked into that first. My bad, thanks for the help guys! Now if only I did not keep getting "System UI has stopped" at random times on aokp...
I've tried changing it from MTP to PTP and turning after switching between the two. I've tried two different roms, one based on 4.0.4 and 4.0.3. I've Tried several different USB cables, including the ones that came with my G2x and Nexus One. I've tried it in a USB 3.0 Port. I've tried using different kernals. Even when I get into recovery, windows still doesn't read somthing is attached. I've been transfering ROMS to it via dropbox. I don't think it's a rom issue as it should still show up in windows when in recovery. Also on those roms I made sure that they didn't have "USB Fast Charge" enabled, as I heard that can cause the issue I'm experience. Thinking it was an issue with CWM, I downgraded it, but still no USB. I'm stuck here. Any help is greatly appreciated.
Their IS a fix for this, but we need the code to get into the PhoneUtil menu and turn USB back on.
It's an issue with Samsung phones apparently, and here's a fix someone found a while ago.

We just need the PhoneUtil code for the Galaxy Nexus and we should be all set.
It's a HARDWARE ISSUE with the latest batch of GNexs.
My issue is definitely hardware. I sent my GNex back and they sent me back a new one which I received yesterday. I checked and this one wasn't previously rooted or Unlocked. It worked for a day (worked as in windows saw it and I could xfer music/books/comics to it) after I get home from work Windows stopped recognizing it. I did NOTHING to the phone, it just stopped being seen by windows. I only used the cable that came with it and charged it the night before using the supplied adapter, but the USB still stopped working. Last resort I did a system restore to the phone and the USB still doesn't show up in anything ,Tried 5 of my Windows PC's A bunch of PC's at work, my friends Mac, my Ubuntu powered Netbook, my Xbox360 and PS3, even the Transformer Prime using the keyboard dock. This is telling me it's a hardware issue with the Device. Might be somthing wrong with the latest batch of GNex's but the USB seems to give out. Even if I put the phone in ODIN mode NOTHING recognizes it. So, before you all waste your time finding a fix, this is 100% absolutly a hardware issue with these phones, I don't know why, but I had Two bad ones in a row, and am Hoping my 3rd isn't borked too.
I have a bad history with Android phones....My first Nexus One wouldn't stay on, so I got a replacement from HTC. My first two G2x's would constantly reboot, It wasn't until the 3rd one that I got a working one. Now I'm hoping I don't have to go through 4 bad Galaxy Nexus' before getting one that actually works!
I have the opposite luck with tablets....the Novo7, Iconia A100 and Transformer Prime have been perfect outa box. This ordeal with android phones makes me seriously consider exchanging the GNex for an iPhone4s....but the iPhone4s screen is SOOOOO tiny!!!
I recently acquired a damaged Kindle Fire. (I'll refer to it below as the 'new' one, even though it is, like my others, used.) The obvious damage is to the screen: it has a fan of cracks on it. However, touch fully works, so that is not my problem.
The problem is that, although the USB port works for charging, I have not been able to establish any USB connection with my Mac. I have other KF's which work with the same connection methods that I have tried without success on this new one. This includes using both regular and factory cables. Nothing works to get the computer to see this and when I start with the factory cable this Kindle just boots normally rather than stopping at the bootloader screen.
This new one has the stock ROM, version 6.3.1, and I have not dealt with any stock ROM since last winter, so I might as well be a noob in that regard. There appears to be no way of turning on ADB debugging, but I doubt that would help anyway, since the Mac's System Profiler doesn't see the KF at all, regardless of what I do.
I do notice that the USB port seems a bit loose and that the cable plug end can move from side to side a bit more than it does on other KF's, but holding it steady in various positions doesn't help.
So, I'm wondering if there's anything I can do with the software that might solve the problem or at least let me get fuller use of the KF, including rooting it and loading apps, without opening the device and repairing the USB port.
Suggestions appreciated.
So my phone is no longer being recognized as a USB device by my computer. Whenever I plug my phone in, I don't see the USB storage option on the top of my phone, nor will my computer even acknowledge that it's been plugged in. This issue has never happened to me before, and it only started acting up just last night. It isn't an issue with the computer OR the cable; I've tried with many different PCs and cables, both third party and official, and I'm getting the same problem. I don't think it's an issue with a broken microusb port, either, since it still charges. Interestingly enough,the computer WILL notice that something has been inserted when I plug it in... if the phone is off. However, the phone only shows up as an unknown device. Also, when I check the battery status, it almost always says that I'm charging via AC even though I'm using USB.
After exploring the forum, I've discovered and tried using *#7284#, but the code refuses to work. (I also tried other codes just to see HOW they work, and none of them will register on my phone.)
I'm currently running CM 7.1, and my phone is rooted. I haven't changed the ROM ever since I started using it, which was about a good year or so ago, and I seldom do any sort of flashing, so I highly doubt it's related to that.
Any suggestions? I thought it might be a dirty microusb port, since I've also been getting the random Car Mode popups as of late, but after cleaning it out, nothing seems to have changed.
