Added flag to the HID report parser to indicate if a device has multiple reports.

Browse source 
SetIdle requests to the HID device driver with a 0 idle period (send changes only) now only affect the requested HID interface within the device, not all HID interfaces.

Apply correct fix to the HID report parser for PUSH items - current HID item attribute stack was being copied in the wrong direction.

Fixed HID report parser not resetting the FEATURE item count when a REPORT ID item is encountered.
