For nut on OpenBSD you need ugen(4). The quick and dirty way to
achieve that is to disablei uhidev* in the kernel. The cleaner way is
to patch usb_quirks.c, as pointed out by somebody else.
You also need r/w permissions for group _ups to /dev/usb* and
/dev/ugen0*, and possibly other things (use ktrace to find out).
