use a k/m and reset the links bt
then pair it again

also post the pid/vid of the controller
and maybe a link to buy one

Folks will need to know more to really be able to help at all. Manufacturer and model number, preferably, and ideally also the USB VID/PID.

Even just a name would be helpful, but it is often not enough; 8BitDo has like four different "Ultimate 2" controllers, for instance, and Sony has two different base DualSense revisions (models CFI-ZCT1W and CFI-ZCT2W), etc.

Hi, thanks for the answers and sorry for that, my controller is the "GAMINJA MG25Z" . I don't really know much about it, i'm sorry. And as I said, it used to work before the update, in my PC with big picture mode still works. But doesn't work while the usb dongle is connected to the steam link.
