Why do you care
Hi Alan&Greg:
We meet a problem that bind usb3.0 port(supper-speed port) with ACPI.
The main problem is that the port index num of ss port in the usb ocre
is mismatched with its counterpart in the ACPI table.
The xhci usb3.0 root hub port's index num is based on 0 in the usb
core(xh
14 matches
