The IOCTL_HID_READ_REPORT control code transfers an input report from a HIDClass device to the HID class driver's buffer.

Input Buffer

To obtain the size of the buffer that is provided by the HID class driver, the UMDF-based HID minidriver calls IWDFRequest::GetDeviceIoControlParameters and supplies pOutBufferSize.

Output Buffer

The HID minidriver returns the device descriptor by filling the buffer that is obtained by calling IWDFRequest::GetOutputMemory.

Output Buffer Length

The size of the buffer obtained by calling IWDFRequest::GetOutputMemory.

Status block

HID minidrivers that carry out the I/O to the device must also:

Requirements
