I changed that.

Is there any way to see what these two devices are?
May the UPS one should be root:nut

$ ls -l /dev/usb
total 0
crw-rw---- 1 root root 180, 96 May 11 00:40 hiddev0
crw-rw---- 1 root root 180, 97 May 11 00:40 hiddev1


PS!
I changed code in drivers/libusb.c
It doesn't fix my problems but I think is nicer code.
