UdecxUsbDeviceInitAddStringDescriptorRaw function

Description

Adds a USB string descriptor to the initialization parameters used to create a virtual USB device.

Parameters

UdecxUsbDeviceInit [in, out]

A pointer to a WDF-allocated structure that contains initialization parameters for the virtual USB device. The client driver retrieved this pointer in the previous call to UdecxUsbDeviceInitAllocate.

Descriptor [in]

A caller-allocated buffer that contains the USB descriptor to add to the device.

DescriptorLength [in]

The length of the descriptor buffer.

DescriptorIndex [in]

The index of the descriptor.

LanguageId [in]

The language identifier of the string. The client driver must define constants for the language support, such as:

const USHORT US_ENGLISH = 0x409;

Return value

The method returns STATUS_SUCCESS if the operation succeeds. Otherwise, this method might return an appropriate NTSTATUS error code.
