Re: Nut can't open Mini-Box OPEN-UPS2 (SOLVED)

Thanks to Michael Gmelin for pointing me to 
https://forums.freebsd.org/threads/nut-2-8-0-generic-ups-blazer_usb-cant-claim-usb-device.90744/ 
and from there to https://forum.opnsense.org/index.php?topic=28695.0.

As the first link says, the problem is that the device is claimed by the 
HID driver. Running the "detach" command fixes the problem (until the 
next reboot).

As described in the second link, I added a line to /boot/loader.conf:

     hw.usb.quirk.0="0x04D8 0xD005 0 0xffff UQ_HID_IGNORE"

and it's fixed permanently.

Thanks again, Michael.
