You don't need to touch Objective-C at all!  IOKit is plain old C.

*I* used Objective-C because it was easier than writing a bare Python 
extension because you don't have to deal with all the argument packing 
and unpacking and the CFDictionaryRef, CFStringRef, etc. are 
transparently bridged into Objective-C types, which are then 
transparently bridged to Python types.  When I'm writing Python 
extensions by hand, I have to look at docs or use another extension as 
a template.  When I'm writing Objective-C code I just write the code 
and link it in and use it.  The same more or less goes with Pyrex.

Probably because it was from memory, or maybe because I might have the 
FireWire SDK installed?  I don't know.  I don't think the USB Prober 
gave me any data when I was using PocketMac, maybe they have disabled 
it somehow in their drivers to maintain their monopoly on BlackBerry 
software for Mac OS X?

I'll do that tomorrow.  The BlackBerry has a much less interesting 
dump, it only has one thing under it and it's of the "vendor specific" 
type (from memory).
