  1. USB-4COMi-SI-M : Isolated 4 Port USB-RS422/RS485

    Hi,

    I'm trying to get working this USB to serial adapter under freebsd 7.
    The driver uftdi, detects the adapter,
    but I'm unable to get any import from newly created /dev/cuaU0-3.

    Is this device supported from the uftdi driver? Should it work and am I
    hitting a bug?

    This is what I have from usbdevs -v:

    Controller /dev/usb1:
