Thanks Francesco, I have now added the symlink to see if it makes a
difference, however, as I was poking around I noticed that there is *no*
hiddev* device at all ... is this an indication that something is amiss with
my kernel?

Anyway, with the modified rule in /etc/udev/rules.d/70-nut-usbups.rules:
ATTR{idVendor}=="075d", ATTR{idProduct}=="0300", SYMLINK+="iDowell",
MODE="664", GROUP="nut"
I still get the same errors.
The symlink itself is not associated with hiddev*, but as follows:
ls -la /dev/iDowell
lrwxrwxrwx 1 root root 15 Jan 3 15:12 /dev/iDowell -> bus/usb/003/056
Of course, since the device seems to be disconnected and reconnected
continuously, the link similarly changes the device file that it points to. A
few seconds later I get:
ls -la /dev/iDowell
ls: cannot access /dev/iDowell: No such file or directory
and then soon after:
ls -la /dev/iDowell
lrwxrwxrwx 1 root root 15 Jan 3 15:14 /dev/iDowell -> bus/usb/003/063
Any ideas what I should be looking for, or what driver might work with this
baby?
