Owen,
Thanks for pointing that out. OK, so the UHCI part is presumably
handled by my kernel. That's built in, not modular, so I won't see it
with lsmod I suppose. The EHCI part I'm not sure about.
I'm starting to wonder if this is a USB 1.0 vs. 2.0 issue. This MB
has 4 USB ports on the back panel in two stacks of two. The Asus manual
says all of those are USB 2.0. I wonder if that can be right? Are all 4
driven by the 00:10:03 USB 2.0 devices?
If so, then where are the 3 USB 1.0/1.1 devices coming out?
Maybe I just have my USB devices plugged intot eh wrong sort of USB
port? I thought USB 2.0 controllers could interface with USB 1.0/1.1
devices...
