Major code

Input buffer

Irp->UserBuffer points to a HID_XFER_PACKET structure the contains the parameters and report to be transmitted to the device. The following members are used:

Input buffer length

The size of a HID_XFER_PACKET structure.

Output buffer

None.

Output buffer length

None.

Status block

HID minidrivers that carry out the I/O to the device set the following fields of Irp->IoStatus:

Information is set to the number of bytes transferred to the device.
Status is set to STATUS_SUCCESS if the transfer completed without error. Otherwise, it is set to an appropriate NTSTATUS error code.

HID minidrivers that call other drivers with this IOCTL to carry out the I/O to their device, should ensure that the Information field of the status block is correct and not change the contents of the Status field.
