The kernel is all one big tree.  The file you're looking for is 
drivers/usb/misc/iowarrior.c.  (Preview at 
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/usb/misc/iowarrior.c). 
The change you're talking about should be fairly straightforward - just 
look for the existing ids.

Step 1 for me has always been to compile a whole kernel. Unfortunately 
that's a bit of learning curve.  I'm not sure which resources to recommend.
