--- Comment #5 from Tomasz "CeDeROM" CEDRO <tomek at cedro.info> ---
I have Sierra EM7305 on Panasonic Toughbook CF-MX4 and the same problem - the
VID/PID is known but the modem is not operational, it needs some additional
setup.

In older laptop Panasonic Toughbook CF-C2 also I had Sierra WWAN modem with the
same problem. There I have replaced it with another device that was working out
of the box.

I know Frank Harvey (dvwerks at cox.net) is Sierra expert and offered help in
solving the problem on the forum nickname phishfry. Maybe we could write a
simple libusb based application that would switch these modems into operational
state for FreeBSD :-)
