On looking at this, I saw the action file was rather different from
other action files, and (as I'm slowly picking on this up) I'd like to
check with you whether the following action file might do the work:

/etc/vdev/actions/scanner.act
[vdev-action]
event=add
path=^bus/usb/*/[001-999]
OS_SUBSYSTEM=usb
VAR_PERMISSIONS_OWNER=root
VAR_PERMISSIONS_GROUP=scanner
VAR_PERMISSIONS_MODE=0664
helper=permissions.sh
daemonlet=true

Afaict, the acls should follow the file permissions and you shouldn't
need to set those.

Ralph.
