I checked with -x usb_set_altinterface and it says
nut_usb_set_altinterface: usb_set_altinterface() should not be
necessary - please email the nut-upsdev list with information about
your UPS
no other difference from the previous runs

Now that's a problem. I am not sure that I can find
1) the original software
2) a (physical) windows machine in the vicinity of the UPS
I will give it a try but for now looks like a dead end. I have 3 of these
UPS. Two of them have dead batteries and since they take 4 batteries each
it makes it harder to justify their repair.
If I find the software and a windows machine what software should I use to
sniff the usb traffic?
Thanks for your help so far. It was really insightful and educational.
