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.

Hi FreeBSDers,
Trying to get nut to talk to my Mini-Box OPEN-UPS2 (FreeBSD 13.3 with
nut-2.8.2 built from ports). I've fixed devfs.rules correctly so that
the /dev entry is owned by user nut.
When I start nut, I get a message "Can't claim USB device
[04d8:d005]@0/0/0: Other error". See below for details including
usbconfig output for the device.
Does anybody have a clue, please.
Thanks in advance for any hints,
Graham
