Friendly Name of avstream based vender specific Usbaudio driver

hi
i am implementing the vendor specific usb audio driver for xp and vista based on avstream. in xp i am getting the correct friendly name for my driver "Test Mic" but for vista the friendly name is like that "microphone (5 - Test Mic" or some time i am getting "microphone (7 - Test Mic".

my bridge pin descriptor is
{ NULL,
NULL,
{ NULL, // default interfaces (NULL, 0 == default)
0,
NULL, // default mediums (NULL, 0 == default)
0,
SIZEOF_ARRAY(PinDataRangePointersBridge),
PinDataRangePointersBridge,
KSPIN_DATAFLOW_IN, // Dataflow
KSPIN_COMMUNICATION_BRIDGE, // Communication &KSNODETYPE_MICROPHONE, // Category
NULL, // Name
0 // Reserved },
0,

0, // Instances Possible

0, // Instances Necessary

NULL, // Allocator Framing (filled later)


NULL, // Intersect Handler }
