Device: GPD Win Max 2 (2023) - Rysen 7 7840U
USB device being used: Rokid Max glasses
The USB C port that has this driver is no longer outputting video or sound. Windows detects that there is an external monitor and that there are external speakers, but neither work.
They have worked after complete reinstalls of Windows, both from Microsoft and GPD, but quickly the output becomes intermittent and completely stops.
I have used USBView and USBTreeView and have found out which port is being used.
It works with the USB 4/Thunderbolt 3 port, but that is an Intel device and driver.
