Recompiling the kernel is not needed. Your previous message already
confirmed this is a permissions problem, since it runs fine if you add
the '-u root' option to the startup of the driver. The most likely cause
is that the 'upsd' user is not a member of the 'uucp' group. You can
verify this by running (as root)

	# groups upsd

The 'uucp' group should be listed. It most likely is not, so you'll have
to make the 'upsd' member of this group by running

	# useradd -G uucp upsd

After that, replug the USB connection or reboot the whole system.
