Hi Folks,
I'm failed to access E173 modem on FreeBSD 9.0 using serial port. Yes, I
got information from the web that this device is not supported yet by the
default driver, and the u3g driver need to be updated. (
I already follow
all the instruction but unfortunately still failed.
Till now i'm stuck with this device. I turn to Ubuntu server, the modem
works well there.

Bellow is output of usbconfig:

# usbconfig
