What are the best-supported usb-serial adapters for use with FreeBSD on arm systems?
I'm specifically interested in Raspberryp Pi 2/3/4 (and maybe 5 someday).

I've been using pl2303 and ft232 but wonder if there might be others worth
considering. Pl2303 are cheap and have lately been working fairly well, but
if there's something better supported or behaved I'd like to know.

Thanks for reading,
