How do I mount a USB to Serial adapter in FreeBSD 5.5?
Posted on 2008-06-10
I need a serial port for development of an embedded system in FreeBSD 5.5. I'm currently running FreeBSD 5.5 in VMware Fusion on OS-X. I have a Keyspan USA-19HS USB to Serial adapter, but if some other USB to Serial device would work more easily, I would happily purchase a different device as part of the solution.
I can mount the serial device on the OS-X host, but sadly, VMware Fusion will not allow me to share the serial device on the host with the FreeBSD system. However, I believe I can mount the raw USB device just fine on FreeBSD--when I plug in the device I see this message in /var/log/messages:
Jun 10 16:43:53 development kernel: ugen0: Keyspan, a division of InnoSys Inc. Keyspan USA-19H, rev 1.10/1.00, addr 2
and when I look in /dev:
crw-r--r-- 1 root operator 228, 1 Jun 10 13:41 ugen0.1
crw-r--r-- 1 root operator 228, 2 Jun 10 13:41 ugen0.2
crw-r--r-- 1 root operator 228, 3 Jun 10 13:41 ugen0.3
If someone can help me to mount this USB device as a serial port, I think I'd be in great shape. Any help will be greatly appreciated,
