Is this stock Raspbian or another variant? If it is Raspbian, I think it might be affected by a Debian issue with libusb-0.1. It is possible to rebuild from source and use libusb-1.0 instead - let us know if that sounds reasonable. You can also check the list archives for previous discussions (although I think we were seeing issues with Tripp-Lite hardware more frequently). Also, sometimes swapping out the USB cable can help. _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
