Oy, Sarah! ;)  I put the ASMedia adapter in my older amd64 machine, and, well,
the stupid thing Just Works(TM) with kernel 3.12.7!  (Yes, with the same disk
docking station, too.)

I can't believe the adapter works perfectly in a different computer.  Have you
seen this kind of thing before?

At the moment I have two machines using your xhci driver and both work perfectly,
so I thank you again :)

I'm not sure where to go with this next.  I could put the adapter back in the
other machine again if you have more patches to test.
