I give this answer a lot: Try another cable. One of the data connections has broken, which lets you still charge but breaks the USB I/O.

[Q] My PC doesn't recognize any of my Devices

So it's been 1 Week since I reformatted my PC and after that day i tried to plug my device using USB and it shows a message saying "Driver software installation failed" and "Unknown Device - Installation Failed" Before plugging my device I already installed Samsung USB Drivers and KIES too but i dont know why my PC doesnt recognize my devices at all, in fact before my PC recognizes them. What should I do? Help me please its been a week and I do a lot of research still I can't fix this problem thanks.

Since you reformatted your pc, did you reinstall all the motherboard drivers? Sounds like the usb drivers could be missing.

[D6633] Xperia won't turn on, Windows doesn't recognized when plugged in

Hey guys
I just got my Z3 Dual today. I was trying to boot into flash mode and using flash tool but it didn't recognize the phone.
Now the phone isn't turning on and when I connect it to the PC, Windows just shows as a "Unknown USB Device (Device Descriptor Request Failed)".
I can't seem to make the phone respond in anyway. Flashtool doesn't list any connected devices.
Did I brick my phone?

First thing i thought was, maybe battery is dead someone, but u must have checked that right? Anyways, If you did manage to brick ur phone, you should probably send it to Sony and claim warranty.

Soft brick help!

Hi all
I've had a soft bricked device now for 4 days I've read almost every post on the net to resolve this issue. So my Samsung S6 SM-G920F is stuck on the blue screen saying "An error has occurred while updating the device software. Use the emergency recovery function in the smart switch PC software." I can get into download mode 'recovery' however my phone will not connect to my computer via usb. With an error message stating "usb device not recognised. The last usb device you connected to this computer malfunctioned and Windows does not recognise it.
I have tried:
Changing cables
Changing computer
Deleting drives - rebooting comp to reinstall
Removing kies
Removing smart switch
Reinstalling smart switch
Reinstalling sub drivers
Editing power options and disabling USB ports
Entered HP BIOS and ran a port check which did however result in failure but then same situation on another HP laptop with working ports.
The device is charging when plugged in but not available to flash and reboot/bootloop.
If anyone has a resolution I will be eternally grateful.
Thanks in advance
