I'm not sure if this should be filed here, under Orac, or somewhere in the Patchbox/Pisound world. Thanks for making and generously sharing cool things. Sorry to bug you about stuff like this.

Describe the bug
Eigenharp pico not recognized by raspberry pi running latest patchbox os.
cp 69-eigenharp.rules to /etc/udev/rules.d in Patchbox OS with ORAC installed

To Reproduce

install the Orac module using the Patchbox Configuration Utility
