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.
