USBD_CloseHandle function

Description

The USBD_CloseHandle routine is called by a USB client driver to close a USBD handle and release all resources associated with the driver's registration.

Parameters

USBDHandle [in]

USBD handle to be closed. The handle is retrieved by the client driver in a previous call to the USBD_CreateHandle routine.

Remarks

A client driver should call USBD_CloseHandle in the driver's routine that handles the IRP_MN_REMOVE_DEVICE IRP. The client driver must call the routine before sending the IRP down the USB driver stack.
