USBC_START_DEVICE_CALLBACK callback function (usbbusif.h)
The USBC_START_DEVICE_CALLBACK routine allows a USB client driver to provide a custom definition of the interface collections on a device.
Syntax
USBC_START_DEVICE_CALLBACK UsbcStartDeviceCallback;
NTSTATUS UsbcStartDeviceCallback(
[in] PUSB_DEVICE_DESCRIPTOR DeviceDescriptor,
[in] PUSB_CONFIGURATION_DESCRIPTOR ConfigurationDescriptor,
[out] PUSBC_FUNCTION_DESCRIPTOR *FunctionDescriptorBuffer,
[out] PULONG FunctionDescriptorBufferLength,
[in] PDEVICE_OBJECT FdoDeviceObject,
[in] PDEVICE_OBJECT PdoDeviceObject
)
{...}
Parameters
[in] DeviceDescriptor
The device descriptor of the device.
[in] ConfigurationDescriptor
The configuration of the device.
[out] FunctionDescriptorBuffer
Pointer to a buffer that contains an array of function descriptors (USBC_FUNCTION_DESCRIPTOR).
[out] FunctionDescriptorBufferLength
The length in bytes of the buffer that FunctionDescriptorBuffer points to.
[in] FdoDeviceObject
The function device object for the device.
[in] PdoDeviceObject
The physical device object for the device.
Return value
If the operation succeeds, the vendor-supplied callback routine must return STATUS_SUCCESS.
Remarks
For a general description of the callback routine mechanism, see Customizing Enumeration of Interface Collections for Composite Devices.
