I took a look at these files but I don't understand what I am supposed
to "guess"?

I just did this, I have a 1.5 MB log file including a battery test
request. I've made the file available at:
http://jdelvare.pck.nerim.net/linux/usbsnoop-apc-back-ups-rs800-battery-test-1.log
I've taken a look but so far I am totally clueless as to how I am
supposed to match the contents of this log file with the features
listed by the usbhid-ups nut driver. Any hint?

Thanks,
