For configuration you can use the TV remote through CEC. Also the remote that came with my device had an USB connector because it’s RF. I don’t know which one you got. For DV play and ng you also need the dovi.ko module that is linked here in the forum (CE-NG Dolby Vision for G12 boxes (u22xj, am6+, raven...)). Finally, there are some reports of the DV Fel not playing perfectly in ce-21. We’re still checking that out.
