The device node for CP2108 Quad USB to UART Bridge Controller on RPi-B+

Kylix

I refer How to use NetBSD on a Raspberry Pi to install NetBSD on RPi-B+. I plug a USB cable on the USB port of PRi-B+ and on the microUSB port of a server. I want to access the server by the minicom on NetBSD. However, I can't know which node is corresponding to USB to UART device correctly, I is always failing to access the server. I have accessed successfully the server by the same way over FreeBSD, which is through /dev/cuaU1. Which one device node in NetBSD is equal to /dev/cuaU1 in FreeBSD?

I use earmv6hf arch of 9.3 STABLE NetBSD on Raspberry Pi B+

Kylix Which one device node in NetBSD is equal to /dev/cuaU1 in FreeBSD?

I don't have any serial-port HW, so I'm guessing here, but, going by the tty(4) man-page, I would try: /dev/tty00, /dev/ttyU0, /dev/dty00, /dev/dtyU0 and similar higher-numbered devices.

A dmesg output from your system should tell us if the controller was configured OK.
