Assuming it's a descriptor file from EasyHID, and you have PBP 2.50 or prior.

A little further down in the file you'll find a ReportDescriptor1.
Inside that, there's an *** INPUT REPORT *** and *** OUTPUT REPORT ***
And each of those has a ...

Code:
    ; report count (number of fields)
    retlw    0x95
    retlw    0x08
The 0x08 needs to be changed to match your array size.
Only 8, 16, 32 or 64 are valid.
