Hello,

I use 2.6.8.1. On 2.6.7 things were OK. My motherboard is an Asus
P4P800, with the Intel i865PE chipset. USB stuff is compiled into the
kernel (not as modules).

When I plug in a USB device it is not recognized. It does not even
appear in lsusb. 

The system works OK with USB devices that were plugged in at boot time.
But when I unplug one, wait some seconds and plug it in again, the
system does npt see it anymore.

On the first plugging-in of any USB device, the following appears in
/var/log/messages :

Is there anything one can do about this?
