Interesting. After my machine hung again and I had to hard reboot, the getty for ttyUSB0 now starts. I'm still not sure where to
enable different speed settings, tell it to run a vt100, as the systemd documentation is fairly confusing IMO. But I'll keep
looking. If anybody knows this off the top of their heads, please share it here.
