Windows Driver Kit DDI reference (nc-udecxwdfdevice-evt_udecx_wdf_device_reset)

EVT_UDECX_WDF_DEVICE_RESET callback function

Description

The UDE client driver's implementation to reset the emulated host controller or the devices attached to it.

Parameters

UdecxWdfDevice [in]

A handle to a framework device object that represents the controller. The client driver initialized this object in the previous call to UdecxWdfDeviceAddUsbDeviceEmulation.

Remarks

The USB device emulation class extension (UdeCx) invokes this callback function to notify the client driver that it must handle a reset request including resetting all downstream devices attached to the emulated host controller. This call is asynchronous. The client driver signals completion with status information by calling UdecxWdfDeviceResetComplete. If the client specified UdeWdfDeviceResetActionResetEachUsbDevice in UDECX_WDF_DEVICE_CONFIG (during the UdecxWdfDeviceAddUsbDeviceEmulation call), this callback is never used. Instead, each connected attached device receives an EVT_UDECX_WDF_DEVICE_RESET callback.
