I can't seem to get NUT to connect to my new PowerWare (Eaton) 5115.
(Linux  x86_64, Gentoo)

# /etc/init.d/upsdrv start
 * Caching service dependencies ...                                     
                     [ ok ]
 * Starting UPS drivers ...
Network UPS Tools - UPS driver controller 2.4.3
Network UPS Tools - BCMXCP UPS driver 0.23 (2.4.3)
USB communication subdriver 0.18
Can't claim POWERWARE USB interface: could not claim interface 0: Device
or resource busy
Unable to find POWERWARE UPS device on USB bus (USB)

What would already 'claim' the UPS?

USB sees the UPS, from lsusb:

Bus 003 Device 005: ID 06da:0002 Phoenixtec Power Co., Ltd UPS
