Nforce2 - usb 2.0 bug

[Paolo]

Hi all.
Asking on Irc (thanx riel!), they suggested to write a sort of bug-report.
I'm using a motherboard Asus A7N8X-Deluxe and the usb modules can't work 
with USB 2.0 devices (while 1.1 work with no problems).
The hardware tested is perfectly working on other computers, but with 
this motherboard the devices are recognized but can't be initialized. 
I've tried different distros (Gentoo, Debian & Debian based, Slackware, 
Mandrake ... and even Qnx, FreeBSD).
Usb 2.0 devices can correctly work if the system is booted using 
Windows, then software-rebooted in Linux, otherwise, they can't be 
initialized.
All the modules are correctly loaded. Usually i don't load uhci_hcd but, 
even modprobing it, the results don't change.
Now i'm using a Gentoo with a 2.6.10 kernel release, but i've tried 
different 2.6.x and 2.4.x kernel versions.

My lspci:

The problems are the same, using devfs or udev (with or without hotplug 
and coldplug).
The firmware is updated.

Thanks in advance
