Hi,
Noted. But whenever I am running "insmod ohci" or other host controller
(ehci or uhci) in grub command line and then "usb", I get always "(hd0,
mdos1) not found error" even for serial modem device.
Please help.
with regards,

Ales,
Yep. The Dell works fine now. :)
I thought it had something to do with missing companion controller.
But it turned out to be the truncation bug.
The Broadcom 5880 works perfectly!
