OK, I'm on dsl un France using an Alcatel USB modem. The source for those drivers has been released by alcatel, and they've been ported to Linux and Free/NetBSD. So I'm wondering how hard it would be to port those to OSX.

Here's the link:
http://www.xsproject.org/speedtouch/

If someone could actually port the driver, it would be great since we've been having trouble finding some one familiar enough with OSX to do so. But all I'm asking is for someone in the know to tell me if it's a simple recompile away (does I/O Kit allow for FreeBSD drivers?) etc.

Thanks for the input.

No, it is not a recompile. IOKit and traditional *BSD drivers are quite different. A few people have written wrappers that handle some of the conversion, but it is still nontrivial.

This is a common misconception. IOKit is very different from the FreeBSD driver API. It's often easier to just completely rewrite the driver, from what I hear.

On the other hand, it'd be nice if someone could write some docs on IOKit drivers from a FreeBSD driver developer perspective.
