it sure looks to me like this is a usb interrupt problem.  i can't
tell from the output of your kernel if the mp table is just missing
or not.  i'm guessing that this mp table just doesn't have entries
for 1:1 mapped irqs.  my first guess (not tried myself) would be
to assume that irq 11 → GSI 11, which is usually ioapic 0, pin 11.
s/11/5 for the other usb port.

you might try adding fake irq entries to your mp table to match,
and see if that works.  :-).  usb is always level triggered.

here's more confirmation of an irq problem.  i wonder if polling
isn't fully tested.
