I was just taking your example. I assume that Apple make the keyboards alike. 
If not we will have to adjust. I did not look too close at the HID

indicates the EJECT, then it is an Apple keyboard and that it works like an 
Apple keyboard.

Can you find the bit or byte that is changing in the report which corresponds 
to the CAPS lock key? Also don't forget to print the first byte which is the 
ID byte.
