Report Descriptor not read correct!

Oleg Nicolaiciuc

Hello All!

I use my own PCB with EFM32GG332F1024 MCU.
I'm trying to run USB HID.

However, my Report Descriptor is not read correctly!
Could someone check my descriptor?

Here is my Report Descriptor:

SL_ALIGN(4)
const char HID_ReportDescriptor[] SL_ATTRIBUTE_ALIGN(4) =
{
    0x06, 0x00, 0xff,                   // USAGE_PAGE (Vendor Defined Page 1)
    0x09, 0x01,                         // USAGE (Vendor Usage 1)
    0xa1, 0x01,                         // COLLECTION (Application)
    0x26, 0xff, 0x00,                   // LOGICAL_MAXIMUM (255)
    0x15, 0x00,                         // LOGICAL_MINIMUM (0)
    0x75, 0x08,                         // REPORT_SIZE (8)
    0x85, OUT_CONTROL_ID,               // Report ID = 0x01
    0x95, 0x40,                         // REPORT_COUNT (0x40=64 Bytes)
    0x09, 0x01,                         // USAGE (Vendor Usage 1)
    0x91, 0x02,                         // INPUT (Data,Var,Abs)
    0x85, IN_CONTROL_ID,                // Report ID = 0x02
    0x95, 0x40,                         // REPORT_COUNT (0x40=64 Bytes)
    0x09, 0x01,                         // USAGE (Vendor Usage 1)
    0x81, 0x02,                         // OUTPUT (Data,Var,Abs)
    0x85, OUT_DATA_ID,                  // Report ID = 0x03
    0x95, 0x40,                         // REPORT_COUNT (0x40=64 Bytes)
    0x09, 0x01,                         // USAGE (Vendor Usage 1)
    0x91, 0x02,                         // OUTPUT (Data,Var,Abs)
    0x85, IN_DATA_ID,               // Report ID = 0x04
    0x95, 0x40,                                     // REPORT_COUNT ()
    0x09, 0x01,                     // USAGE (Vendor Usage 1)
    0x81, 0x02,                     // INPUT (Data,Var,Abs)
        0xC0,                           // End Application Collection
};
