I’ve 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’t 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?
