I have an MGE Ellipse Pulsar 500 UPS (USB ID 0463:ffff), connected via USB, and since upgrading to F10 from F8, usbhid-ups will not start.

Version-Release number of selected component (if applicable):
[root@detritus ~]# rpm -qa | grep ^nut
nut-client-2.2.2-4.fc10.x86_64
nut-2.2.2-4.fc10.x86_64
[root@detritus ~]# uname -r
2.6.27.15-170.2.24.fc10.x86_64

How reproducible: Every time

Steps to Reproduce:
1. Configure a UPS with driver = usbhid-ups
2. Attempt to start ups service

Actual results:
[root@detritus ~]# service ups start
Starting UPS driver controller: [FAILED]
Starting upsd: [ OK ]
Starting UPS monitor (master): [ OK ]

This looks very similar to bug 461374, but that was apparently fixed. The documentation tells me that this is definitely the correct driver to use (I think I could use mge-shut if I used a serial cable instead, but my serial port is in use for something else).
