[Andrey R. Masalov]

Hello, everybody!!!

I have eletegroup 648fx-a2 motherboard on the sis chipset. There are 3 
USB 2.0/1.1 host controller in my mother.

My OS is

 > uname -a
FreeBSD  6.1-RELEASE-p3 FreeBSD 6.1-RELEASE-p3 #3: Thu Jul 20 23:05:04 
KRAST 2006     root@:/usr/src/sys/i386/compile/PNCKKERNEL2  i386

There is support USB 2.0 in my kernel.

I connected 2 USB 2.0 devices scanner mustek bearpaw 2448cs plus and 
photo camera olympus c-480z. I try connecting this devices in all USB 
ports. But my OS watched only this:

 > usbdevs -dov

addr 1: full speed, self powered, config 1, OHCI root hub(0x0000), 
SiS(0x0000), rev 1.00, device uhub0

 port 1 powered
 port 2 powered
 port 3 powered
 port 4 powered
 port 5 powered
 port 6 powered
 port 7 powered
 port 8 powered

These devices works as usb 1.1. But I wont, that these devices works as 2.0.

I have read man usb && man usbd && man usbd.conf && man ohci && man uhci 
&& man ehci and have searched in the web. I couldn't find necessary 
information. :( It's bad. :)

Please help me. I'll be glad to receive from you any information.
