Hi, I have used STM32G0B1RE microcontroller which is configured as Custom HID Device using STM32CubeMX. I have changed the report descriptors to the following
__ALIGN_BEGIN static uint8_t CUSTOM_HID_ReportDesc_FS[USBD_CUSTOM_HID_REPORT_DESC_SIZE] __ALIGN_END =
{
/* USER CODE BEGIN 0 */
0x06, 0xa0, 0xff, // USAGE_PAGE (USB Control Panel Gen 2)
0x09, 0xa5, // USAGE (Usage1)
0xa1, 0x00, // COLLECTION (Physical)
0x09, 0xa6, // USAGE (Usage2)
0x85, 0x01, // REPORT_ID (1)
0x09, 0xa7, // USAGE (Usage3)
0x15, 0x80, // LOGICAL_MINIMUM (-128)
0x25, 0x7f, // LOGICAL_MAXIMUM (127)
0x75, 0x08, // REPORT_SIZE (8)
0x95, 0x06, // REPORT_COUNT (6)
0x81, 0x02, // INPUT (Data,Var,Abs)
0x85, 0x02, // REPORT_ID (2)
0x09, 0xa7, // USAGE (Usage3)
0x15, 0x80, // LOGICAL_MINIMUM (-128)
0x25, 0x7f, // LOGICAL_MAXIMUM (127)
0x75, 0x08, // REPORT_SIZE (8)
0x95, 0x05, // REPORT_COUNT (5)
0x91, 0x02, // OUTPUT (Data,Var,Abs)
/* USER CODE END 0 */
0xC0 /* END_COLLECTION */
};
