Well, judging by the code in hidmon, you know enough about the  
programming interface needed. If you want, you could take the hid.h  
header and add some function prototypes for things that you feel are  
missing.

I have some Python code in the libhid source tree that I am using to  
prototype a new HID parser, but it's nowhere near the point that I  
could start writing C source from it.

Another idea that we kicked around in the pre-0.2.0 days was having  
multiple backends - on Linux, you could choose between libusb and the  
kernel hiddev interface, and this could even allow porting to Win32.

Then again, libhid came about because the Linux hiddev IOCTL  
interfaces did not properly support collections of HID usages, and  
that problem has been fixed since the early 2.6 kernels.
