The USB sniffer I am using [1] is not exactly user-friendly. I
have to
restart the system for every new capture (otherwise I am unable to
reset the capture file), and the capture doesn't end when I exit the
application. It is also not possible to manually start or stop the
capture. Is there any better USB sniffer application you would
recommend?
I don't know. I've not used windows for years...
maybe that one, but it's a shareware!

OK, I've given it a try, it is quite powerful, unfortunately I don't
know much about USB so I may not be using it in the best way.
Anyway, I managed to capture some data and I hope it will help. I've
asked for HID decoding and URB decoding. The files are here:
http://khali.linux-fr.org/files/nut/
idle-*.htm files are captures when I didn't do anything. test-*.htm
files are captures when I triggered a battery test.
I tried finding differences between the captures, and found that the
test capture had the following entries not present in the idle
capture:
If I am interpreting this correctly, the software is sending a HID
SetReport(0x16, 0x01) followed immediately by SetReport(0x16, 0x00).
From your previous email:
Path: UPS.Battery.Test, Type: Input, ReportID: 0x16, Offset: 0, Size:
8, Value: 6.000000
Path: UPS.Battery.Test, Type: Feature, ReportID: 0x16, Offset: 0,
Size: 8, Value: 6.000000
You are correct that the Input is already mapped to ups.test.result,
but it should be possible to specify that writing to UPS.Battery.Test
will start a battery test. ("Feature" reports are writable as well as
readable.)
I am not sure how that would send the 0x01 then 0x00 with this driver,
though - maybe Arnaud or Arjen can help with that part.
