Query: NOT USB, and NOT XP compliant.

If you care about USB (rather than serial) and you care about it 'just working' with your windows XP, then buy something else.I got sent the one with a serial cable, and some terribly poor software.I used windows XP's UPS control panel (power management) and I think I had to say it was an APC serial device.No idea if it's doing the right thing - my confidence is low with this product.However, if you don't mind serial, and running other s/ware - it's probably OK.
