I was going to say "no", but lucky I checked. They are all coming off the same 
hub. I have a USB keyboard, mouse, and three external drives, which 
necessitated a hub, at least for the time being.

The hub worked up until last week when I added a kernel change and some 120 
updates (the system hadn't been used in a while). I have a feeling that broke 
something. This is a dual-boot machine, and the drives are there under Windows. 
I can't attribute it to anything else.

It works on the same machine, without touching or moving anything. This machine 
is dual-boot. Booting into XP, it works perfectly.
