I suspect you may have a low-level USB issue on your machines. I've tested
on Win2k3 quite a lot recently, and never encountered this problem.
Assuming you are following the directions in "install.txt" when manually
installing the driver (specifically that you're changing the driver on the
"American Power Conversion USB UPS" and NOT the "Batteries -> HID UPS
Battery") the only thing I know of that would randomly cause Windows to not
find a suitable driver would be a mismatch in VID/PID. This would be caused
by bad USB data from the device, which could be from bad cables, flakey USB
HUBs, bad USB host drivers, etc. I would suggest looking for some sort of
problem like that. The USB driver has not changed from 3.14.x to present,
so randomly switching between versions is not actually accomplishing
anything other than reinstalling the driver.
