How do I use multiple reports and report ids

[cnn123666]

I want to use the hid_composite and hid_generic_inout functionality together
I wrote it like this, but it doesn't work

#include "Adafruit_TinyUSB.h"


#if defined(ARDUINO_SAMD_CIRCUITPLAYGROUND_EXPRESS) || defined(ARDUINO_NRF52840_CIRCUITPLAY)
  const int pin = 4; // Left Button
  bool activeState = true;

#elif defined(ARDUINO_FUNHOUSE_ESP32S2)
  const int pin = BUTTON_DOWN;
  bool activeState = true;

#elif defined PIN_BUTTON1
  const int pin = PIN_BUTTON1;
  bool activeState = false;

#else
  const int pin = 12;
  bool activeState = false;
#endif



enum
{
  RID_KEYBOARD = 1,
  RID_MOUSE,
  RID_CONSUMER_CONTROL, // Media, volume etc ..
  RID_GENERIC,
};


uint8_t const desc_hid_report[] =
{
  TUD_HID_REPORT_DESC_KEYBOARD( HID_REPORT_ID(RID_KEYBOARD) ),
  TUD_HID_REPORT_DESC_MOUSE   ( HID_REPORT_ID(RID_MOUSE) ),
  TUD_HID_REPORT_DESC_CONSUMER( HID_REPORT_ID(RID_CONSUMER_CONTROL) ),
  TUD_HID_REPORT_DESC_GENERIC_INOUT(64,HID_REPORT_ID(RID_GENERIC))
};


Adafruit_USBD_HID usb_hid(desc_hid_report, sizeof(desc_hid_report), HID_ITF_PROTOCOL_NONE, 2, false);

void setup()
{

  usb_hid.setReportCallback(get_report_callback, set_report_callback);
  usb_hid.begin();

  pinMode(pin, activeState ? INPUT_PULLDOWN : INPUT_PULLUP);

  Serial.begin(115200);

  while( !TinyUSBDevice.mounted() ) delay(1);

  Serial.println("Adafruit TinyUSB HID Composite example");
}

void loop()
{
  delay(10);

  bool btn_pressed = (digitalRead(pin) == activeState);

  if ( TinyUSBDevice.suspended() && btn_pressed )
  {
    TinyUSBDevice.remoteWakeup();
  }

  /*------------- Mouse -------------*/
  if ( usb_hid.ready() && btn_pressed )
  {
    int8_t const delta = 5;
    usb_hid.mouseMove(RID_MOUSE, delta, delta); // right + down

    delay(10);
  }

      keycode[0] = HID_KEY_A;

      usb_hid.keyboardReport(RID_KEYBOARD, 0, keycode);

      has_key = true;
    }else
    {
      if (has_key) usb_hid.keyboardRelease(RID_KEYBOARD);
      has_key = false;
    }

    delay(10);
  }

  /*------------- Consumer Control -------------*/
  if ( usb_hid.ready() )
  {

    static bool has_consumer_key = false;

    if ( btn_pressed )
    {
      usb_hid.sendReport16(RID_CONSUMER_CONTROL, HID_USAGE_CONSUMER_VOLUME_DECREMENT);
      has_consumer_key = true;
    }else
    {
      if (has_consumer_key) usb_hid.sendReport16(RID_CONSUMER_CONTROL, 0);

A bit late, but if you use a Generic IO + ID you can only use 63 byte for your data since the first byte is the message ID - try using this:

uint8_t const desc_hid_report[] =
{
  TUD_HID_REPORT_DESC_KEYBOARD( HID_REPORT_ID(RID_KEYBOARD) ),

  TUD_HID_REPORT_DESC_MOUSE   ( HID_REPORT_ID(RID_MOUSE) ),

  TUD_HID_REPORT_DESC_CONSUMER( HID_REPORT_ID(RID_CONSUMER_CONTROL) ),

  TUD_HID_REPORT_DESC_GENERIC_INOUT(63,HID_REPORT_ID(RID_GENERIC))
};

Hello!

I am trying to get Raspberry Pi Pico to identify itself as USB Keyboard System Control and USB Keyboard Consumer Control.

Using the example in the repository and the example in this thread, I only see this identifying as keyboard and mouse. Here is the output from dmesg:

[ 7773.161701] input: Raspberry Pi Pico Keyboard as /devices/pci0000:00/0000:00:14.0/usb1/1-2/1-2:1.2/0003:239A:CAFE.0064/input/input132
[ 7773.218577] input: Raspberry Pi Pico Mouse as /devices/pci0000:00/0000:00:14.0/usb1/1-2/1-2:1.2/0003:239A:CAFE.0064/input/input133
[ 7773.218921] hid-generic 0003:239A:CAFE.0064: input,hiddev0,hidraw2: USB HID v1.11 Keyboard [Raspberry Pi Pico] on usb-0000:00:14.0-2/input2

How can I make this identify as USB Keyboard System Control and USB Keyboard Consumer Control?

In dmesg it should look something like this:

[ 7566.525673] input: Raspberry Pi Pico System Control as /devices/pci0000:00/0000:00:14.0/usb1/1-1/1-1:1.1/0003:04D9:1702.0063/input/input130
[ 7566.582565] input: Raspberry Pi Pico Consumer Control as /devices/pci0000:00/0000:00:14.0/usb1/1-1/1-1:1.1/0003:04D9:1702.0063/input/input131

Thanks
