@Rafiot Probably shouldn't merge this until we confirm the udev rules work on all raspberry pi versions. I'll add a 2.1 release tag after the merge.

Sounds good, I'll work on it tomorrow, or later today.

Thank you very much!

Looks great, it seems the USB keys are mounted properly, I'm doing a few more tests, but I think we will officially do a release today :)

Thank you very much!
