The device driver is ax88179_178a.c There are still some bugs in the xhci ring handling that can affect the ax88179_178a driver+hardware. I needs the fix to ensure that the ring boundaries are aligned with usb packets, otherwise packets can get lost and the tx side can lock up. It also doesn't work at all with the asmedia xhci silicon.
