Hi, my phone only charges when it is connected to the PC, it isn't showing options for MTP, MIDI. I was on Pixel Experience when this started happening, I tried enabling USB debugging, tried different cables. None worked. I thought it might be a ROM problem, so I flashed AEX Modify, still the issue persists.
My phone is shown as Unknown device (Device descriptor failed) something like that in Device manager. Any help would be welcome.
May b a suitable driver is required for ur pc..mtp driver like this....google it

... 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.

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...
Hello, been using CyanogenMod (marshmallow) for 3 weeks now and last thursday my zenfone 5 stopped charging and is no longer recognized in 2 computers. I tried using other cables, other charges, other computers and today I even tried installing another rom (Resurrection Remix MM). Any chance this is software and fixable and not hardware? Thanks.
____
Did some research and someone else on the internet solved this by taking the battery off his phone while it was charging and putting it back. Anyway to do something similar with the zenfone non removable battery? Will open the phone to take the battery off it while it's still plugged be a good idea?
Same problem here please help

Current ROM Resurrection Remix L
I have a bricked Lenovo K30-W I'm trying to fix (freezes on startup). My computer (Windows 10) won't recognise it when I connect it to the USB port. In device manager, the phone is displayed as unknown, with error "Device descriptor request failed". I tried connecting to different USB version ports, I tried installing multiple different drivers and software, but nothing helped. Adb doesn't recognise it as well, even if I boot the phone to fastboot with volume+power buttons. Any other ideas? Thanks.
Update: problem seems fixed. I used another USB cable and plugged it into an older version USB port. It is now recognised.
Hi XDA members. I need your assistance.
My phone has been acting up lately. Plugged in to my laptop using the type C cable that came together with the phone and the message USB device not recognized pop-ed up. Tried re-updating the drivers @ Device Manager, but still, the problem persist. Tried changing laptop and still, the problem persist!
Before this, I can easily transfer my stuffs from my lappy to my phone and vice versa. But now, even the status bar menu option to choose "Charging/Transfer file/etc" isn't appearing..
@ Device Manager, under the Universal Serial Bus controllers tab, it's written there "Unknown USB Device (Device Descriptor Request Failed) .
My mi a1 is rooted and is on Jan update btw. Wanted to unroot & flash stock fastboot image to update to Feb update, but if I can't even connect to the pic, how am I suppose to use the MiFlash Tool?
Please help.. Feeling so restless now :crying:
Edit : Tried every method I've read in the internet, from updating drivers, unplugging power source, uninstall and re-install drivers. The only thing that I have not tried is changing cable. If it works after using a new cable, then please kindly ignore this thread/remove it please moderator. At the same time, wondering if root process has got anything to do with this..
Edit : Found the issue. It is the cable all along! Changed to a new cable and everything works fine.
Just had the exact same issue here, found your post, changed cables and everything is fine again. Thanks
Same issue with Mi A1
Hi,
I'm facing the same issue. My Mi A1 is not recognied on laptop running Windows 7 64-bit. Earlier it used to work without any problem.
My Mi A1 is running on Android 9 with Sept 2019 updates and it is not rooted.
I've tried changing cable and with developer options on and off. Nothing working.
Any suggestions to overcome this issue.
Best,
1. it happens when you had faulty cable.
2. your phone's usb port is faulty
first replace your cable if problem persist clean your phone's usb port and if both not worked repalce your phone's usb charging port
I'm happy that you already solved the issue, but for future reference:
1) If it has already worked on that PC, probably the cable is not a data cable but a charge-only cable (~faulty USB cable, but not really)
2) If it has never worked it's possibile that is a driver problem, use this tool to install ADB, Fastboot and Drivers: https://forum.xda-developers.com/showthread.php?t=2588979
3) Unlikely, but possible, you entered the network Diagnostic Mode. Just turn off debug/restart the phone.
i have the same issue. I also tested on other PCs. I have laptop with w7 x64, it also doesn't work on w10 x64 too. When i connect A1 to pc, nothing happens in the device manager. The phone is just charging. I have debugging as on and default configuration usb as transfer files. Version os - 10.0.0.12 with unlocked bootloader and root.
The cable is good because in the previous month it worked on it. Please help me with this.
I have same problem. My phone memory is full and I have to transfer files to free it up. Some one please help. I wonder if this has to do with the security update done recently.
same problem here, recognizes nothing, only the load works...

Check your socket - usbc, I had a damaged socket, I gave it back for warranty and changed it. I was just charging the battery.

How about hard resetting the device, will it work
This must be a generic flaw with the Mi A1 as mine is doing exactly the same. I suspect it's the USB-C port itself as it's got steadily worse over the months. I have an Outlook task to remind me to backup my phone using FreeFileSync. Everything is backed up anyway to the cloud but I do like to keep a copy of the high resolution photos as Google reduces quality with the free unlimited photo storage option.
It's charging fine so not too worried. Just need a different way to transfer the photos off the phone. I do have access to a business OneDrive account.
Working in IT, I'm not the world's biggest fan of the USB-C port. It's not as robust as the old USB-A port.
My X720 entres normally in these modes , but pc doesn't recognize device. I tested with different ports, pcs and cables. All same. I notice that in device manager that recognize it as an uknown usb device , failed to read descriptor error 43. My drivers are fine, work flawlessy with my Le 2. My phone charges normally. Also OTG doesn't work . Any suggestions ?
Had the same problem with my x727 what i did was (while leaving the phone connected to the pc:unistall the driver and then reconnecting the phone to the PC) that fixed my problem
