No luck with daily live image.

Microsoft TypeCover keyboard only works when the xhci support is disabled.

I also can read data from /dev/hidrawxxx but if I attach an external USB keyboard and switch to a console (ctrl-alt-f1), the TypeCover still doesn't work: it is actually a kernel problem, not a Xorg problem.

Maybe the xhci problem (which also affects Bluetooth and Wifi of the Surface Pro 2) it is related to this kernel warning:
[code]
[ 1.028259] xhci_hcd 0000:00:14.0: cache line size of 64 is not supported
