Can't open device /dev/ttyUSB0

[Benny-Git]

I tried getting my USB IR head to work with this container, but ran into issues where it could not open the meter:

[Oct 07 20:59:39][]     ===> Start meters
[Oct 07 20:59:39][sml]  open(/dev/ttyUSB0): Permission denied
[Oct 07 20:59:39][mtr0] Cannot open meter
[Oct 07 20:59:39][]     Startup failed: Meter open failed.

I finally figured out that the user doesn't have the right permissions, as USER nobody is set in the Dockerfile. Is there a specific reason for this? Otherwise please accept my pull request to change this.

Running as root is dangerous and should not be the default setting. You can run your docker image as root with
"docker run [...] --user root [..]"
and override the USER setting in the Dockerfile
