This is just a best guess and no guarantees that it will work at all

I have a Belkin serial UPS and am using the downloaded
Unix/Solaris/Linux software for it.
On setup it only asks for the name of the serial port, If you were to
try the USB version and use the serial port software and tell it that
the device was on /dev/ttyUSBxx it might work...... (assuming that you
had the usbserial module loaded)
