The cdc_msc device example works fine. Isochronous OUT transfers hit a babble error (DOEPINT bit 12) on every packet I am not really sure why that is.

The nrfx 3.14 commit which is used in get_deps.py is a little outdated so it predates the renaming done in nrfx 4.1.0 which reads:

Renamed nRF54LM20A Eng A to nRF54LM20A.

in the nrfx changelog
