Looking at the output from the Tripplite UPS I wrote about lately, this
doesn't seem to be due to a bug in the parser.

I think that the UPS is trying to tell us the following. Peter Selinger
already figured out many of these about a year ago (for the same device),
I added some missing ones:

byte 0, bit 0-6: unused
byte 0, bit 7:   UPS.PowerSummary.PresentStatus.InternalFailure
byte 1, bit 0:   unused
byte 1, bit 1:   UPS.PowerSummary.PresentStatus.ShutdownImminent
byte 1, bit 2-7: unused
byte 2, bit 0:   UPS.PowerSummary.PresentStatus.ACPresent
byte 2, bit 1:   unused
byte 2, bit 2:   UPS.PowerSummary.PresentStatus.BelowRemainingCapacityLimit
byte 2, bit 3:   UPS.PowerSummary.PresentStatus.FullyCharged
byte 2, bit 4:   UPS.PowerSummary.PresentStatus.Charging
byte 2, bit 5:   UPS.PowerSummary.PresentStatus.Discharging
byte 2, bit 6:   UPS.PowerSummary.PresentStatus.FullyDischarged
byte 2, bit 7:   UPS.PowerSummary.PresentStatus.NeedReplacement

So it may be a good idea after all to disregard HID paths that end in
0x00000000, even if the hidparser would be fixed. Although it would be
nice to get a confirmation that this is indeed to be interpreted as
'unused'.
