I currently have the ORB drive plugged into a LinkSys 4-port hub
that is plugged into one of the two USB ports on the back of my
machine. The HCD inside my computer is OHCI. When the HCDs are
scanned, both are reported as having four ports. Matt Dharm has
mentioned seeing this before, where a machine's internal HCD,
when scanned, is reported to have more ports than are exposed on
the back of the machine. I'm not sure if that has anything to do
with why this particular OOPS is occuring, though.
I suppose I could remove the LinkSys and simply plug the ORB into
one of the machine's USB ports and see if that helps.
