Hello,
I've installed the M2 then r140 on my Nexus 4 in 4.2.2 and have since frequent USB modem drop that I never had before with the official and rooted versions.
I've had this without modifying kernel parameters.
it looks like it is an USB issue:
- when I plug the USB, charging goes on but I need to deconnect/reconnect the plug so the USB be recognized to use it as a modem
- when my PDP changes (IP renewal), there is no deconnexion
Thus I guess this is an USB issue, any idea ?

Hi folks I have a rooted N7 and have used plenty of different ROMs in the last 2 years. Since installing KK 4.4.4 I cannot connect to my computer by USB, neither Windows 8 or Linux.
OTG is working as I can access external USB cards, there is nothing wrong with the USB leads, needless to say I have tried different leads in different USB ports, the tablet still charges when connected by a USB cable.
In settings, storage has MTP activated, I have tried PTP and it still will not work.
In developer I have activated USB / Android debugging.
I am using multirom and have done so since it came out
My main rom is MAHDI 2.7
Secondaries areCM11 20140903 and pac_grouper-1-20140903
Any help would be appreciated.
Think it's solved
All my other Android devices connect with my computers by usb so I have to conclude that there is something wrong with the N& OTG port.
... and is no longer recognized when connected to a computer via USB, meaning I can't return to stock to get ready for the Lollipop OTA.
Got a rooted Nexus 4 running the latest PA beta.
What happens when connecting to PC:
- On two different Windows machines: systray popup saying "USB device not recognized. The last USB device you connected to this computer malfunctioned etc.". In device manager it says "Unknown USB device (device descriptor request failed)"
- On elementary OS, based on Ubuntu 12.04: nothing, besides charging.
No USB debugging connection notification on the Nexus 4 either when plugging in.
What I've tried (USB debugging enabled, all relevant drivers installed):
- Settings > Storage > USB computer connection > check Camera PTP (used to be required in order to get an RSA key prompt when connecting to a computer, now it does nothing)
- Flashing latest stable CM to see if PA was to blame. Made no difference.
- Uninstalling device through device manager in Windows and reconnecting. No effect. Driver update doesn't work either, finds nothing.
- Using Wugfresh's Nexus toolkit to see if that worked, but that obviously doesn't work either when the device isn't recognized, same with the Universal Nexus Linux Toolkit on Linux.
- Scouring the net for solutions and coming up with nothing
I have flashed factory images before on this phone without problems. Should I consider it a hardware failure by now, or is this a known issue with a fix?
Try a new wire, different usb port on computer, finally look into cleaning your charging port on the phone/replacing it.

Tried three different cables, every port on two laptops, no joy - my girlfriend's phone connects normally.
Wouldn't replace the charging port, then I'd just get a new phone since it's a 2 years old Nexus 4. If only there was a way to flash the factory image using only TWRP.

Flash this in twrp http://forum.xda-developers.com/showthread.php?p=47476426
Sent from my Nexus 5 using XDA Free mobile app
Thanks jd1639, that seemed to be exactly what I was looking for -
- but then I had an extremely blonde moment and formatted everything in TWRP, wiping the ROM I was gonna flash in the process, on a device where USB file transfer doesn't work anymore
My phone is now a paper weight.
Have you tried the file manager in twrp yet? I've found it connects when nothing else will...
Hi i have a nexus 7 (2012) everything was working fine until android 5. The device was slow and almost unusable. Then the 5.0.2 update came out and guess what? I updated it and now my laptop wont recognize the device so i tried a different cable and nothing. I plugged the nexus 7 in my second computer and nothing not even the sound that means you plugged something in the usb port. So i went to my brothers house and tried his computer.... the same... nothing. We plugged his nexus 7 (2012) 5.0.2 wich is the exact same device as mine and it works so we thought that it was the usb connector on the device and we switched my connector with his....NOTHING happens. computer wont recognize the device, no sound, no pop-up, no ADB detection. Does anyone have the same problem or a solution on how to downgrade 5.0.2 back to 4.4 without usb cable?
Thank you
Did you tried out to start n7 into fastboot mode and recovery mode?
Is usb not available also there?
fastboot and recovery mode also has no USB. absolutely nothing happens. when i connect the device it charges but the lightning icon does not appear on the battery in the status bar. and its not the usb port on the N7 i changed it.
?????????????????
Same here
I have the same Problem - a N7 GSM with 5.0.2 and no communication via USB.
I have tried different computers with Win7 and Ubuntu14.10. As well as differnt cables. (And all combinations of that work with my HTC M7, by the way)
Under Linux, not even lsusb shows the device, or dmesg shows any connection to a usb device.
To be completly honest, I did not give much love to my N7, I have been using it hardly. But when I did, I have been flashing some differnt Roms and testing different bootloaders so this might be some kind of my fault.
i updated to 5,1 and still the same problem so i assume its hardware related. but i know it is not the USB connector because i tried it on my brothers N7. and it works
Mine is quirky, comp recognizes it and can order boot but sideload and push to device don't work. Its odd.
Hello everyone I've got an issue with my Nexus 4 which is why I registered, as I simply don't know what to do anymore.
My Nexus 4 is not recognized via USB at all, there is no connection sound and ist does not appear in the device manager.
It is charging and does show USB charging if I tap the battery icon.
Things I tried:
Uninstall/Install Driver with and without WugFresh Toolkit (USBDeview)
different Pcs (different USB Ports)
different USB cables which all worked with other mobile devices such as Samsung S3/4/5 mini
checking and unchecking MTP,PTP and Usb debugging
fastbootmode
factory reset
replaced the USB flex cable as i figured it would be defect
I tried to root it with some of the apps available bur none of them work with LMY48T.
I think it might be firmware related but because I didn't flash a Custom Recovery the last time I rooted it I have no possibility to flash another rom.
The root access was lost when the last OTA Update arrived which is why I can't install a custom recovery via the clockworkmod Rom Manager.
The Pc I'm working with is running on Win 10 I'm running out of ideas.
Please help me, thank you
So my wife note 4 (sprint) is stock (6.0.1) and works great except for it will not connect via USB to my windows 10 PC. Device manager shows:
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.
I would like to root in order to debloat but cannot connect to the PC in either download mode or just on.
I have tried installing Kies and drivers also I am using the original USB cable with no hubs.
Try another cable and another USB port.
It could be the on device micro usb socket. This type of socket is pathetically fragile and does have a high failure rate. I have seen this issue time after time...The older the device (and let's face it, the N4 isn't exactly the current flagship) the more often this port is the culprit.
