Hi Colin,

I have a Yoga 3 Pro running openSUSE Tumbleweed.  I know that it's different hardware, but this might give a clue where to look.

In "lsusb -t" you are looking for:
 “Human Interface Device, Driver=usbhid”v

The only thing that I had not working out of the box was screen rotation in “tent mode”, but I understand that even that works in some distros.
