Sarah, I just fixed my xhci bug for US$19.99 :)

#lspci | tail -1
04:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 03)

This new NEC usb3 controller does everything the ASMedia controller should have
done from the start.  I can even power-up the outboard usb3 disk docking station
after the computer is running and still everything Just Works :)

I appreciate all the debugging work you've done to fix the ASMedia problem but
I think it's time to quit now.  If hundreds of irate linux users complain about
the same bug then I'll be happy to test more patches.

Until then... :)
