I think you need to own the device node. We have in /etc/logindevperm:

/dev/vt/console_user	0400	/dev/removable-media/dsk/*	# removable media
/dev/vt/console_user	0400	/dev/removable-media/rdsk/*	# removable media
/dev/vt/console_user	0400	/dev/hotpluggable/dsk/*		# hotpluggable storage
/dev/vt/console_user	0400	/dev/hotpluggable/rdsk/*	# hotpluggable storage
