Hi Steve,
actually my driver is just a normal "static" DMusUART & MPU401
combination with some "dynamic" add-ons.
Even if I only use the static part (the Subdevice created with
InstallSubdevice in StartDevice and specified in the INF-file),
I cannot instanciate the capture-pin of this filter...
Have you also based your driver on DMusUART & MPU401?
If so, have you changed any of the filter & pin-properties
of the driver? My driver is based on the samples of the WDK
6000. I have seen that the sample in the 2000 DDK differs
a little in the exposed properties...
Best regards,
Tobias
