So, after a few days of messing around w/ Bootcamp and XP on the Mini, the biggest issue I’d run into was the fact that WinXP was trying to power down my USB Root Hubs to save juice. Unfortunately, I DIDN’T KNOW THIS until I came across this thread over on Google Groups.

I was experiencing the same symptoms except without the luxury of being able to quit Outlook and AIM, etc.. My keyboard & mouse would stop responding after a little while of being back on the Mac side of the KVM. After I would try to switch back to XP, nothing would respond.

However, changing the settings suggested in post #2 of that thread so far seem to do the trick.

Those XP Weenies are going to just love the Mac noobs looking for help to problems that have been solved in 2001.
