Rather than restarting the driver, you probably want to start by figuring out what else is claiming the driver. You can only have one program talking HID to a USB device* at a time. Do you have any other power management software on your system which might try to grab this device? * technically, one per interface, but most UPSes have one HID interface. -- - Charles Lepple _______________________________________________ Nut-upsdev mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/nut-upsdev
