MxPS= 8 Ivl= 10ms In general, if you see your UPS model in the S: field, which
means Manufacturer= , Product= , and SerialNumber= , and you
see Driver=hid in the I: field, you know the UPS has been
recognized and is bound to the correct driver. If your UPS doesn't appear in the list at all, check the obvious
things: The UPS must be powered on, and a cable must be properly
seated in both the data port of the UPS and one of your machine's
USB ports.
