tail -f /var/log/messages

Produces the following when I plug in the UPS connector:

device using
uhci_hcd and address 17

UPS] on usb-0000:00:1d.3-1

Plugging in a flash memory stick produces a quite 
different result and
the device name is obviously /dev/sdc1.   The flash 
memory device is
being processed differently.

And then cat /proc/bus/usb/devices
Produces the following for the UPS:

And for the flash memory device:

And then:

I guess I still don't know how to identify the UPS device 
for the configuration file, perhaps /dev/UPS?
