Wrong perms on ugen0, read carefully:
7.6.4 Allowing Scanner Access to Other Users
if you want ugen0 appears with the right permissions once you plug your
scanner.  The current devfs scheme you use (Cf. your previous mail)
should work if you boot directly with your scanner plugged and not if
you plug it later.

This is a problem, a USB scanner under FreeBSD should use uscanner(8)
driver nothing else.  I assume your scanner is not seen by uscanner(8),
i.e. not supported or just not defined in uscanner.c
Try to add an entry for your scanner in uscanner.c, rebuild uscanner.ko,
etc. and retry.
