The EHCI controller will only talk to USB2 devices. The card will have either OHCI or UHCI built in to talk to USB1 devices attached to the same ports, so you need to load whatever of those is appropriate. You can usually tell with;
lspci -vvv | grep HCI (That will also show Firewire host controllers but you don't seem to have any) On Sun, 14 Sep 2003 [EMAIL PROTECTED] wrote: > > I am trying to make a logitech 4000 webcama work with my linux-box ( > Debian testing and my own 2.4.21 kernel).
