I=E2=80=99ve now tried the USB2 ports (after obtaining an appropriate = cable), and both the USB stick and the Huawei modem appear to be working = as expected on the USB2 ports. The USB2 ports on the APU are not exposed in the case, and I don=E2=80=99t= really feel like trying to drill a hole into the case to try and get = the adapter cable out. The only ports available on the case are the two = USB3 ports. How could I go about debugging the XHCI driver that apparently has = trouble communicating? Is there some more debug bits I can enable?
