it should be already handled, the startup service exits if the BeagleConnect Freedom USB device is not found and then later plugging in the device user can run /opt/gbridge.sh to start manually

3 years ago How do I change what devices are connected and/or manifests that are loaded?
Currently this needs to be done manually, manifest is prepared(combined) during compile time, so for each endpoint with different clicks/on-board devices the greybus sample needs to be recompiled with the click names in config: https://github.com/jadonk/greybus-for-zephyr/tree/mikrobus#trying-out-different-add-on-boardsdevices-over-mikrobus for devices on-board(not actual mikroBUS but same abstraction is used) we can describe over Zephyr DT https://github.com/jadonk/greybus-for-zephyr/tree/mikrobus#describing-on-board-devices-through-zephyr-dt

Looks like we need to put this in a udev rule.
