All the drivers listed as examples in /etc/sysconfig/ups are for devices 
connected by serial cable.

If your UPS is connected via USB, use MODEL=hidups.  (If that doesn't 
work, try MODEL=newhidups.  The only other USB-enabled driver is 
energizerups, but that's brand specific.)  The DEVICE will be something 
like /dev/hiddevX (where X is a digit.  The device will be created at 
startup, so you should not need an entry is /etc/udev/rules.d.

On boot, I see:

   Sep 10 12:43:20 yankee kernel: hiddev96: USB HID v1.10 Device [APC
   Back-UPS ES 650 FW:818.w1.D USB FW:w1] on usb-0000:00:04.2-2

The device created is:

   # ls -l /dev/hiddev0
   crw-rw----  1 root root 180, 96 Sep 17 12:52 /dev/hiddev0

My /etc/sysconfig/ups has

   MODEL=hidups
   DEVICE=/dev/hiddev0
