I'm not sure I do either :-) On a mouse I tried here I got very
different information than that:

Report descriptor:
Collection page=Generic_Desktop usage=Mouse
Collection page=Generic_Desktop usage=Pointer
Input   size=1 count=1 page=Button usage=Button_1, logical range 0..1
Input   size=1 count=1 page=Button usage=Button_2, logical range 0..1
Input   size=1 count=1 page=Button usage=Button_3, logical range 0..1
Input   size=8 count=1 page=Generic_Desktop usage=X, logical range -127..127
Input   size=8 count=1 page=Generic_Desktop usage=Y, logical range -127..127
Input   size=8 count=1 page=Generic_Desktop usage=Wheel, logical range -127..127
End collection
Feature size=1 count=1 page=Generic_Desktop usage=Motion_Wakeup, logical range 0..1
End collection
Total   input size 4 bytes
Total  output size 0 bytes
Total feature size 0 bytes

But I don't know enough about how this is supposed to work to make
sense of the difference.
