Hi, I updated to latest Android 12, and I don't know if that has to do anything with it, but now when I connect my phone via USB-C on my PC and want to transfer some files, It keeps saying USB device not recognized. I unlocked dev. and enable usb debbuging, but still same. I even try usb-c to usb-a cable same problem. Any suggestion ?

 

P.S

It was showing option on notification swipe for charge only, file tranfser, midi... but now it is only charging. Cable is data transfer 100%

Hi there, I am facing the same issue whereby the error msg "The last USB device you connected to this computer malfunctioned, and Windows does not recognize it."

Try reconnecting the device, If Windows still does not recognize it, your device may not be working properly.

Trying to connect my Samsung S21 Ultra to my desktop, which is a Windows 11 PC. - 17 April 2022

I've also got this problem on my S21 Ultra all of a sudden.

My phone doesn't even acknowledge when i attach a usb-c lead. So annoying.

I want to transfer files from my camera and my drone to my phone but it just doesn't see the drive when i attach it.

Just stopped working for no reason.
