The problem with these devices is usually trying to convince it to
be a modem.  The basic recipe it to do a websearch for the command
the modem requires and, if that's not available from the driver,
add it.  I restructured the u3g driver in -current earlier this
year to make it easier, but I can't remember if that stuff is in
5.1.

Meanwhile, some webpage suggested this AT command to turn the device
into a modem permanently.  Maybe you can try running it from OS X
and see if it helps?

AT+ZOPRT=5
AT+ZCDRUN=8

(of course it would still be nice to see the driver patched to
handle this)
