What I mean is, the M10 tableet only supports USB 2.0. Having the XHCI
driver built won't help you to get USB 3 working.

If the device doesn't work over USB 2.0, there is likely some other
driver missing for that specific device, rather than the generic XHCI
support, since your tablet doesn't support USB 2.0. There are many
peripheral devices such as your DVD drive, for which drivers not
enabled in the Android kernels which are used for phone/tablet images.
