PROPSETID_VIDCAP_EXTENSION_UNIT

The PROPSETID_VIDCAP_EXTENSION_UNIT property set is new for use with the USB Video Class Driver.

This property set is supported for devices that implement a vendor-specific extension unit. Vendor-supplied property pages and applications access this property set through the generic IKsControl COM interface.

Clients of the USB video class driver can make the following requests of filters or nodes:
