If it works with sudo, it might be worth checking which "groups" your 
main user is a member of.

Perhaps adding yourself to groups "video", "plugdev", or something would 
help.

There is a list of available groups in /etc/group


And to add a group to a user, be careful to use the -a (--append) *and* 
-G (--groups) options to usermod.  Sometimes it's forgotten and the 
target user ends up in only the new group which has various repercussions.

So, for adding video group membership to user "me", something like:

# usermod --append --groups video me



Hopefully this is helpful and not too error-riddled advice.
