I'm not sure when you say "dynamic" if you mean changing over time or
whether you just want to have more than one instance of the same subdevice,
as you originally said. If it's the latter, you can do that easily enough by
defining GUIDs for each of your subdevice names in your INF file and then
selecting the appropriate one in your topology initialisation when creating
the bridge pins, e.g.
INIT_PIN (PIN_MASTEROUT_DEST,
CurrentPin,
&KSNODETYPE_LINE_CONNECTOR,
SubdeviceName[SubdeviceInstance],
Index);
where SubdeviceName is an array of GUIDs corresponding to the names defined
in the INF file.

Ok, thanks! So to repeat, in Windows7 the GetPinName method is the way
to go, in Vista dynamic pin names are not possible and in XP the
friendly names are displayed. Is that correct?

install more than one subdevice of the same filter? Right now I see two
devices but both have identical names (Line). Would like to see Line1,
Line2... how can this be done?
