How to include a 2nd input report page

[locodog]

I've managed to get a diy device transmitting a 64 byte input report, if possible I would like to increase this to 2 input reports. I am not too sure as to how to go about this,
(All though it says gamepad its actual usage is a DJ software controller and works on rawInput)

Something has to happen to the report descriptor, and I'd have to include my extra inputs in the firmware code but is there more to it then that?

Code: [Select]

static const uint8_t PROGMEM gamepad_hid_report_desc[] = {
0×05, 0×01, // USAGE_PAGE (Generic Desktop)
0×09, 0×05, // USAGE (Gamepad)
0xa1, 0×01, // COLLECTION (Application)
0×15, 0×00, // LOGICAL_MINIMUM (0)
0×25, 0×01, // LOGICAL_MAXIMUM (1)
0×35, 0×00, // PHYSICAL_MINIMUM (0)
0×45, 0×01, // PHYSICAL_MAXIMUM (1)
0×75, 0×01, // REPORT_SIZE (1)
0×95, 0×80, // REPORT_COUNT (128)
0×05, 0×09, // USAGE_PAGE (Button)
0×19, 0×01, // USAGE_MINIMUM (Button 1)
0×29, 0×80, // USAGE_MAXIMUM (Button 128)
0×81, 0×02, // INPUT (Data,Var,Abs)
0×05, 0×01, // USAGE_PAGE (Generic Desktop)
0×26, 0xff, 0×00, // LOGICAL_MAXIMUM (255)
0×46, 0xff, 0×00, // PHYSICAL_MAXIMUM (255)
0×09, 0×30, // USAGE (X)
0×09, 0×31, // USAGE (Y)
0×09, 0×32, // USAGE (Z)
0×09, 0×35, // USAGE (Rz)
0×09, 0×36, // Usage (Slider)
…….43 more sliders.
0×09, 0×36, // Usage (Slider)
0×75, 0×08, // REPORT_SIZE (8)
0×95, 0×30, // REPORT_COUNT (48)
0×81, 0×02, // INPUT (Data,Var,Abs)
0xc0 // END_COLLECTION
};

To support two Input reports, each must have a Report ID > zero. Or add a Feature report.
