I am running Linux mint Vera (21.1) on a somewhat old computer motherboard (2013), ASROck H61M-VG3, where I have no USB 3.0 port.
Thus, I decided to buy a USB 3.0 expansion card (PCIe x1) I plugged the card into PCIe x1 slot (which is advertised to be sufficient to power the 4 connectors), but just to be safe in the safe side I also plugged the molex adapter.
When I plug a USB device on the USB 3.0 port it gets powered, but there are stability issues: my mouse work for some seconds then stop, my RGB keyboard light is on but when pressing button there are no input my USB wireless adapter get laggy and timeout like interrupt browsing on the internet (TIME OUT).
Here is my
01:00.0 USB controller: VIA Technologies, Inc. VL805/806 xHCI USB 3.0 Controller (rev 01)
I have read somewhere on the internet about firmware update or grub config?
