No, that one's a standard serial port, driven by sio as well, and creates /dev/cuad0, /dev/cuaU0, maybe some /dev/tty* as well, I don't know. > Do you have the correct driver for the converter loaded next to ucom? > The ucom manual page gives a list of them. Yes, uplcom is the right driver. (Or at least I think so, because the device and manufacturer ids that usbdevs -v gives me match those in /usr/src/sys/dev/usb/uplcom.c .) Besides, without the uplcom module loaded, I only get an ugen device, so it seems to attach to the device ok. Cheers Benjamin
