The one you’re looking at doesn’t have /policy/ in the path. Try the one
that does.
Now I understood, added on top
sys-usb dom0 allow
and it works as supposed.
Many many thanks Awokd

Thanks all for the help...making progress...really appreciate the responses
As I continue to explore the new 4.1rc3 another issue comes up that I can't remember experiencing with 4.0 and it seems important:
When I try to back up my system and insert a WD external hard drive I get an error when I try to mount it, specifically "Error mounting /dev/sda1 at run/media/user/easystore: unknown filesystem type 'ntfs3,ntfs'
Backing up Qubes OS to NTFS seems a bad idea to me. Why not use a dedicated medium/partition formatted with a unix filesystem like xfs?
