New Superdrive won't accept discs
MBP 2019. LG previous external disc drive worked well plug & play. Update to recent OS; now LG won't work. Bought NEW apple superdrive. Connected via multiple hub access for USB to C on MBP. Superdrive will NOT accept discs. Appears to not be receiving electrical input. Plug/unplug. Restart computer.. Restart computer and do immediate "hold option, command, P and R"... No change. Disc drive appears dead. Won't accept discs. Brand new, came this past Friday.
