Try the newhidups driver (renamed to "usbhid-ups" in 2.2.x). As root,
run "newhidups -u root -x vendorid=1234 -x explore -DD", replacing
"1234" with the actual vendor ID of your UPS.

You can determine the vendor ID with "lsusb".

The "-x explore" option is basically a test mode that lets us see what
is necessary to support the UPS in a more automated fashion. It may
also be that they are using the USB HID class as a USB-to-serial
bridge, but I have seen a few indications in other emails that this
UPS might be able to work with newhidups, or a future version of it.
