Has anyone had any luck getting this modem to work under FreeBSD ? I
have been trying to modify the driver to get it to recognize and
send the unit into modem mode, but no luck. I even tried setting the
unit into permanent modem mode first from Windows as referenced in
http://www.matt-barrett.com/?p=5
but no luck yet
usbdevs shows it as

Looking through the modemswitch code, I grabbed out the string that
it sends the modem. Googling around, I found 2 different versions.
Both seem to work, however, the secondary ports do not with either
string. Not sure what it exactly does however.

I am able to fireup ppp and surf / download from there. Anyone have
