Problem Description:

Randomly, the USB keyboard or mouse, or both, freeze. If I unplug/plug the
freezed device, it works again. Notice that this does not append when the device
is connected directly to the tabletpc.

When a device freezes, I have the following message in /var/log/kern.log :

Apr 22 13:19:27 tabletpc kernel: drivers/usb/input/hid-core.c: can't resubmit
intr, 0000:00:0c.2-5.3/input0, status -32

0000:00:0c.2 being the USB2.0 NEC Controller (rev 02) (lspci -vvv).

Steps to reproduce:

Infortunetaly, I am not been able to find a way to reproduce the problem.
Sometime, I can use the USB keyboard and mouse several hours without any
problem, but sometime the USB keyboard or mouse freeze several during one hour.
