Probably because it doesn't have drivers for them. If there's no matching driver, it won't pull up a useful nub to stick on it.
The right thing happens in the end. There is no need for drivers on some interfaces, and they must be used on others (eg ones that implement the USB modem protocol or the various USB to serial chips).
A good way to look at this tree is the Mr. Registry app that is one of the targets in /Developer/IOKit/firewire/FWOffice -- despite its name, it lets you look at the whole tree, not just IOFireWire.
That makes it clearer. It is still not remotely like two hours work. (It may be for you however). I'm not going to implement all this but will point anyone else who does want at it. (The return on having to learn all this IOKit stuff, Objective C and how to map Objective C into Python is way too low.)
I'd have to do a lot of reading up on that to see how to get dumps of USB traffic.
There is a USB Prober under /Developer/Applications/Utilities (BTW I have found everything you mentioned under a different path than you said so I don't know if you were typing them from memory or have a different dev kit).
I could run the BlackBerry Desktop via VirtualPC (or on a real PC) to figure out how the modem stuff works, the rest I could probably get by reverse engineering PocketMac.
Email me the device dump of the device from the USB Prober. You'll probably want to do that on the bitpim-devel list.
