All,
Something has changed in 15.4 related to access serial devices over USB in 15.4 and I can't figure out what?

I suspect this may be a group issue. In 15.0 there was the adm group GID 485, that I made myself a member of. (I'm not positive this is the group at issue, but...) The adm group is not present in 15.4.
What group does the device file belong to? Your user should belong to that group.
Is this the culprit? All other groups seem to be common between 15.0 and 15.4.
If not the adm group -- what else could it be? I had no issues using ttyACM0 as my user in 15.0 and now in 15.4 it seems I lack some type of permission to use it.
