Ok, OpenBSD experts: I'm seeing this when I plug in (what I assume is a serial device) to an OpenBSD 6.3 box:
ugen2 at uhub3 port 2 "Prolific Technology Inc. USB-Serial Controller" rev 1.10/3.10 addr 4
Shouldn't I be seeing an additional line in dmesg telling me which ucom device it is? I'm stabbing around with `cu -s 9600 -l /dev/cuaU3' but keep getting
cu: open("/dev/cuaU3"): Device not configured
(cuaU0 -- U2 respond from a built-in modem)
How do I solve this?
@jpmens It doesn't attach as a ucom, so you can't use cu to access it. OpenBSD supports Prolific PL-2303 USB serial adapters so if this one is compatible it's manufacturer and product IDs must be added to the table in /sys/dev/usb/uplcom.c. Run "usbdevs -v" to get those IDs and either add them to that table directly or add new manufacturer/product ID defins via /sys/dev/usb/usbdevs and use those if you know what you're doing. Otherwise just send the dmesg and output of "usbdevs -v" to tech@.
