Thank you for the response. I have been confused about how to start NUT and at one point I was loading both NUT and ups-monitor at startup. I believe this may have accounted for the extra instance of usbhid-ups. However, I now load only NUT at startup and the problem continues. To create a clean test, I enabled NUT in sysv-rc-conf and rebooted. Here are the messages I extracted from syslog after the reboot. It just continues cycling until I stop NUT. Note that there is one error message about failing to login on UPS.
