[Nut-upsuser] can't find UPS on openwrt/arm

[Matus UHLAR - fantomas]

Hello,

I run TP-Link WR2543ND router with openwrt installed. versions:

kernel - 3.8.3-1-eef5f2649dd28f8ed1d4fd9b737acdc7
kmod-hid - 3.8.3-1
libusb-1.0 - 1.0.9-1
libusb-compat - 0.1.4-1
nut-driver-usbhid-ups - 2.6.5-2

I have installed NUT but it can not find the UPS while lsusb can:

according to strace, the files in /dev get opened, it just seems that the
device is not even considered. Is this problem of NUT or maybe libusb?
