Are you running the hyperion daemon as ‘osmc’ or as another user?
I’ve followed this guide: Home · hyperion-project/hyperion Wiki · GitHub
Which advises to use the hyperion.service for systemd running as the user ‘osmc’.
I’m getting the following error when running the daemon in the foreground:
Found a lightpack device. Retrieving more information...
unable to retrieve serial number from Lightpack device(-3): LIBUSB_ERROR_ACCESS
Lightpack device found: bus=1 address=5 serial=
unable to open device(-3): LIBUSB_ERROR_ACCESS
Unable to open Lightpack device. Searching for other device(-3): LIBUSB_ERROR_ACCESS
No Lightpack device has been found
Tried with udev rules to change hiddev0 and hidraw0 to group osmc like Sam did with a few other input devices.
But still the same error
