Thanks.  It looks like you have a few modifications to the source code
- that's fine, but it makes it hard to line up the debug messages to
the code I have - can you obtain the same logs using the latest
seabios from the master branch of the seabios git repo?  ( git clone
git://git.seabios.org/seabios.git )

Also, can you provide the output of "lspci" and "lsusb -v" in the
working setup and the output of "lsusb -t" in both the working and
non-working setup?

My initial reaction is that it seems similar to previous xhci reports
of devices renegotiating to super speed after initially being detected
as high speed.  Can you also test with the patch at:
