APC UPS not found by xfce4-power-manager or upower in slackware 14.1
In slackware-14.0, the command 'upower -d' lists both information
about the upowerd daemon configuration and a USB-attached APC UPS.
In slackware-14.1, only the upowerd info is listed by this command. apcupsd and apcaccess work normally on both systems (same machine, same hardware, dual boot). 14.1 (kernel 3.10.17) loads a module named 'hid_generic' which doesn't exist in 14.0 (kernel 3.2.45), but otherwise the module differences are what one would expect.
In 3.2.45, the APC device is /org/freedesktop/UPower/devices/ups_hiddev0. Both slackwares run the same upower slackpackage version(0.9.17), as released.
