Status block

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

• Information is set to zero.
• 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 IRP to carry out the I/O to their device should ensure that the Information field of the status block is zero and must not change the contents of the Status field.
