If what @mw46d said works, check the logs with dmesg.
The device works in one mode -03e7:2485 Movidius Ltd. Movidius MyriadX when ready to accept connections, then 03e7:f63b 03e7 Luxonis Device when it is working (booted, running an app). It reconnects between these two states which could cause it not to be found again.
Thanks,
