after further checking, it seems that the issue lies in
"libusb_compat - 0.1.4-1" present in current OpenWRT trunk.
After moving to OpenWRT 12.09 containing "libusb - 0.1.12-3" the UPS is
detected just fine.

Detected a UPS: EATON/Protection Station 800

I'm getting other error:

libusb_get_interrupt: Connection timed out

but this may be standard process, is it?

now I wonder if nut could support libusb-1.0 (does it?)
