Query regarding USBH_HID_GetReport

[PSaba]

Hi I am trying to read a report of USB HID device from my STM32 USB Host code.

I am able to read the report descriptor successfully from USBH_HID_GetHIDReportDescriptor call.

I wanted to read the 0xD0 report value

using

if(USBH_HID_GetReport (phost,

                    0x01,

                    0x07,

                    HID_Handle->pData,

                    HID_Handle->length) == USBH_OK)

However, I see only 4 bytes of data in HID_Handle->pData while all others are zeros.

Please find the attached the report descriptor data.

Can someone tell me the correct way to use USBH_HID_GetReport function and expected values in HID_Handle->pData after this call??
