Actually, for the serial 'liebert' driver, it will only detect OL/OB/LB. We haven't had much luck with the USB firmware on other Liebert units, but if it's anything like some of the other UPSes out there, you may need to power the UPS completely off (unplug from the wall, no LEDs on, etc.) before switching between USB and serial. Also, running the usbhid-ups driver with debugging enabled may shed some light on the problem. _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
