this is a hotplug problem

- Copy the files libhidups and libhid.usermap (from nut/scripts/hotplug)
to /etc/hotplug/usb. libhidups might be adapted to the nut user of your
system (ie "nut" on RH)
- Change the perms on /etc/hotplug/usb/libhidups to 755 (ie using chmod +x ...)
- unplug / replug your USB cord
- relaunch newhidups in debug mode

it should now work...
