The HidD_GetSerialNumberString routine returns the embedded string of a top-level collection that identifies the serial number of the collection's physical device.

BOOLEAN
  HidD_GetSerialNumberString(
    IN HANDLE  HidDeviceObject,
    OUT PVOID  Buffer,
    IN ULONG  BufferLength
    );

Parameters

HidDeviceObject

Specifies an open handle to a top-level collection.

Buffer

Pointer to a caller-allocated buffer that the routine uses to return the requested serial number string. The routine returns a NULL-terminated wide character string.

BufferLength

Specifies the length, in bytes, of a caller-allocated buffer provided at Buffer. If the buffer is not large enough to return the entire NULL-terminated embedded string, the routine returns nothing in the buffer.

Return Value

HidD_GetSerialNumberString returns TRUE if it successfully returns the entire NULL-terminated embedded string. Otherwise, the routine returns FALSE.

Comments

Only user-mode applications can call HidD_GetSerialNumberString. Kernel-mode drivers can use IOCTL_HID_GET_SERIALNUMBER_STRING.

The maximum possible number of characters in an embedded string is device specific. For USB devices, the maximum string length is 126 wide characters (not including the terminating NULL character).
