Replying to [comment:3 mmlr]:
> You're saying that the USB mouse doesn't work, but do you by that mean
that **only** the USB mouse doesn't work? Or does USB not work in general?
Have you tried plugging in different devices into different USB ports? You
have two EHCI controllers in that system, so maybe only one of them is
affected here.

Thanks mmlr, USB mouse works again by plugging in different USB port. Then
I tried USB stick. USB stick also works by plugging in different USB port.
So It seems USB does not work in general with one of two controller as you
say.
> The routing table looks complete, so everything seems to be routed from
an OS point of view. It's possible however that the information provided
by the BIOS is faulty, i.e. the pins not actually being routed to the
inputs that are returned in the routing table. In that case a BIOS update
might resolve the problem.

BIOS seems latest, I'm waiting for new BIOS...
