Re: USB problem: /dev/ugen* dynamically auto-reconfigures to root:operator 644, so non-root user unable to access USB devices even if wanted

I would probably just use a wildcard:

	perm	ugen* 0666

This makes the rules only apply to devices arriving in the future,
you also need:

	devfs rule applyset

to make them apply to currently available devices.

I have no idea what goes on here.

Yes, probably a good idea.
