One thing to watch out for with APC and USB is that it was the case with
their earlier units that once you had connected them up using USB the only
way you could get them to go back to serial was to power them down
completely.  They may have fixed that, of course.

Having said that, we never did get our APC USB-capable units to work
reliably with our Linux boxes.  They're all on serial or SNMP cards now.
