I tried contre different operating systems w7 - w10-w11 but as soon as I connect the phone does the driver search and then tells me "USB MTP device" failed, Now I tried to colelgare my old mi9 t pro and recognized it right away! I flashed the xiaomi eu, then I rooted the phone, immediately after I connected the phone to the pc to put files inside and it worked!!! Then at the imporvviso has no longer worked the usb debugging! I reflected the rom and put the root back! I reviewed and revised the svuluppatore options, the various settings to understand if 'it was some wrong entry. or tried on several new PCs! I have installed any type of driver. I tried the cable on another phone. I tried to put an otg stick and I am recognized by the phone (so I have no problems with the usb connector!) Isn't there some developer who could help me?
