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.

Whenever I plug my phone into my computer now all it does it show the little charging light in the top left corner of the EVO, and not the notification asking to turn on usb storage in the pull down menu, or give any errors, and nothing pops up on the computer.
Recently, I started to have usb problems where the notification on the phone was flashing on and off and the usb connected sound on the computer kept going off (like the phone was connecting and disconnecting to the usb port on the computer every second), but I thought this was a cable problem and since I didn't need usb at that moment, I brushed it off.
I'm pretty sure my phone still charges fine because the light goes on. No, It isn't a problem with the cables or the computers because i've tried multiple cables and computers. I don't understand what the problem is because my charging still works fine and I don't get error messages, it's just that usb won't connect at all anymore

If that doesn't work, you may have a hardware defect, and it'd be best to unroot and take it to sprint.

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.
Hi guys,
My GNex has a problem. Many users seem to have a similar problem but theirs seem to be hardware related and I'm pretty confident mine is software related.
It started a few months ago when my GNex wouldn't charge through the wall charger. I was on a trip with my friends so I didn't have access to a pc and wasn't able to troubleshoot further. The charging icon would appear when the phone was off but when I turned it on it didn't charge. I played around with the phone for about two hours, rebooting, Googling for solutions, changing the USB connection modes in the Storage settings. When I changed from Next Launcher to Stock launcher and rebooted everything was working fine again. However I think it was only a coincidence. Then the problem didn't occur again until now and this is why I think it's software related. If hardware would have been broken the problem wouldn't just have fixed itself like that.
It happened 3 days ago but somehow fixed itself again. I was troubleshooting the issue with my GNex connected to PC and installed Nexus Root Toolkit by Wugfresh. During install my phone rebooted on it's own and suddenly USB worked perfectly again!
However yesterday I forgot to charge and my GNex died. On reboot the issue was back.
"Symptoms":
Phone won't charge with any wall charger (and any cable) unless off
Phone will charge through USB in any mode but PC will not recognize it and install it as unknown device.
USB Debug Icon and Connection Mode notification do not appear in status bar upon PC connection
OTG doesn't work and apps like "Stickmount" do not detect external drives
Attempts:
Gently bending the "tongue" inside the micro usb on the phone in case there is a bad connection
Reinstalling drivers on PC
Rebooting device in different modes including fastboot
Using different batteries
NOTES
This problem started after latest 4.3 update. It has only occured after battery completely runs dry. I have 3 batteries (a bit excessive I know) and an external battery charger so charge is not the issue, I just really want to understand what's going on with my phone.
I'm not ready to Factory Reset or replace the USB port yet, those are last resort options to me. Any other options, especially software related, are very welcome. I am on stock 4.3 only rooted and with CWM recovery.
In Testing menu (type *#*#4636#*#* in Dialer) under Battery Settings my phone also says Charging (AC) when connected through USB. Hope this helps.
Been Googling around for two days now so I decided to make my own thread. Any help is appreciated. Sorry for this very long post.
Fixed it! Tried bending the tongue inside the micro usb again, forced much more this time, everything is working again, for the moment
So, I got back this weekend and realized that the data connection over USB cables stopped working, even in recovery(PhilZ) mode.
Last weekend it was working fine, and throughout the week it was kept turned off with no disturbances.
ADB doesn't detect the phone.
Power is supplied normally, so the phone still charges. Computer plays the USB detected sound when plugging in/out.
Tried different cables, different computer, and verified that while it works normally on my One m8, it does not on my HOX.
On SlimKat rom, stock kernel.
Any help, guys? I'm really hoping it's not a hardware problem.
I am running the latest Android 13 QPR beta release. Ever since I updated, I've been having a connection issue in every app. Every 2 minutes or so, my phone "loses connection", regardless of Wi-Fi or data, regardless of signal strength, any app will struggle to connect for a few seconds. My phone doesn't actually lose connection, it's weird. Most apps will just reconnect and go on about it's business after about 10-15 seconds of connection issue, but some refuse to "reconnect", so I have to close the app and reopen. After weeks of this, I decided to reformat my phone and go back to the stable android 13 release, by opting out of the beta and receiving the OTA to go back to stable. I did this with the intention of installing a custom ROM.
However, the OTA took an abnormally long 2 hours to complete. Upon completion of the update, my phone gave the the installation successful message with a restart. Upon restarting, I was greeted with the bootloader and the message "No operating system installing. Cannot boot". After a few minutes of restarting and fumbling around to no avail, eventually it booted back into my beta build. I breathed a sigh of relief. This was, however, not the end.
At this point, I thought "that was frightening. Best off just to try to install the factory image through ADB". So I go on to plug in my USB cable, and I see the notification that USB was connected. I try to click the notification to switch to file transfer mode, and then it disappears, and Windows loses connection to my phone. I'm now no longer able to get my P6P to recognize that it is plugged into a computer, and my computer refuses to detect my phone. It does however charge off the PC connection though. I've tried updating drivers, switching cords (including the factory cable, the usb-c to a cable that I usually use with this phone with success), USB 2 ports, USB 3 ports, restarted my computer, factory reset my phone, quadruple checked USB debugging was enabled, and nothing seems to work.
I'm stuck on the beta build. Cannot do anything with ADB. Cannot do anything with recovery mode, as apply update from SD just returns an error. I'm hoping I'm just missing something simple. Are there any other suggestions or ways to get around needing a computer for anything?
Thanks for reading!
This can be closed. After hours of frustration, I tried a cord that doesn't seem like it should work. It's a "universal" cord (one with a micro-USB connection and an adapter for USB-C and lightning). Never give up, you never know ¯\_(ツ)_/¯

I always have mtp set as default. Better to be safe than sorry
I do, as well. Connection wasn't being detected on either side. I was also getting a pop-up on my computer saying something along the lines of "the last time this device was connected, it malfunctioned. Windows cannot recognize the device." That's why I initially thought drivers, and only tried a few cords. But I got desperate and reached deeper in the bin. Thanks for the pointer, though.
