Hi,

I'm in the middle of a struggle to port the linux
nozomi(Option GloberTrotter 3G+ HSDPA cardbus adapter) driver to freebsd.

Any ideas are appreciated. Thanks!

I did a presentation at BSDcan on writing devices drivers:

The handout is a cheat *** of useful functions for writing a device
driver...
