u3g panic

[Nick Hibma]

Mike, and others,

We are working on this panic at the moment and there will be a driver out 
for inclusion in 7.2 (hopefully).

It seems to (almost) make ZTE MF626 work as well (mode switch does not work 
reliably yet). According to Mike Tancsa this driver also makes his Novatel 
device work without having to manually switch the device.

I'd appreciate it if poeple could gives this driver a try to see whether it 
works for them too.

	http://people.freebsd.org/~n_hibma/u3g.html

I am using it as we speak to submit this message and upload the driver 
sources, change the HTML text on that page.

Cheers,

Nick
