Probably not since the sanner is turned off. But, let me give it a go.
Okay, tried that. Nope, not a conflcit. Uplugged the scanner and tried
the front port. No go.

And to confirm things, I swapped the sanner cable with the the one I
was using to connect to the audio. The audio works on the rear; the
sanner works on the front. So, probably the power?

I'm not sure how I'd test that. But, like you said, it's unlikely.

> dmesg |tail should tell you about usb 2.0 and cat /proc/interrupts should

Yes, interesting about the irqs.

My small brain, after looking at some syslog stuff seem to indicate
that the front panel ports are USB 1-9 and USB 1-10. I am assuming
that my expander port (which has keyboard, mouse and other "stuff"
attached) is also on USB 1. So, could just be that I'm adding too much
stuff to port 1?

I'm sure that I had the audio device working on the front panel, but
it might be that I moved the rear ports around ... ending with my
multi-usb on the same port as the front panel.

Too bad the MB doesn't label this stuff !!!!
