That should be without /sys, as per the above.

Do make sure you did a 'udev reload' btw.

This requires a single argument:

onerng_verify.py /dev/ttyACM0


Note btw that the onerng package for Debian (and likely the other
Linux-based platforms) primarily provides udev rules.
This thus to make live easier.

If one knows one only has one ttyACM<x> device, one can also just pass
/dev/ttyACM0 in /etc/default/rngd or the location where rngd gets started.

The udev scripts provided effectively start rngd with the right param.
Which is useful, but static definition works too.
