USB Problem in 2.6.8

[eolyte <eolyte@free.fr>]

Hi,

i'm using a sid and have noticed a strange problem with usb on 
kernel-image-2.6.8-686 and kernel-image-2.6.8-686-smp on my computer.

It seems that only the devices that are plugged before the uhci_hcd module is 
loaded are detected. These are working properly, but if I plug another device 
after, it doesn't even appear in /proc/bus/usb/devices, and idem if i 
unplug/replug one which was working properly.

Worse, if i try to unload uhci_hcd, the system is freezed, and need a hard 
reboot.

I tried under 2.6.7, and have no problem.
I also tried to disable hyperthreading but the problem is still there.

So my motherboard is an Asus P4P800

Here's some pieces of a lspci :
0000:00:00.0 Host bridge: Intel Corp. 82865G/PE/P DRAM Controller/Host-Hub 
Interface (rev 02)
0000:00:1d.0 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #1 
(rev 02)
0000:00:1d.1 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #2 
(rev 02)
0000:00:1d.2 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #3 
(rev 02)
0000:00:1d.3 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #4 
(rev 02)
0000:00:1d.7 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB2 EHCI 
Controller (rev 02)

I don't know what information could be useful, so if you need more, just ask 
me, i'll be glad to help.

Thanks,

Boris.
