[Nut-upsuser] Problem connecting Ippon Innova TBE 2000 UPS (USB/HID) with blazer_usb driver

[Jim Klimov]

As commented in the replica discussion at
https://github.com/networkupstools/nut/issues/2951 my immediate suspicion
is about non-ASCII description from `ups.conf` confusing the parser.
Logs from the driver start-up attempts (probably as `systemctl status
nut-drver at innova`) would show more.
