I think your understanding of the "rules" is correct, but the rules have
some problems in the real world. I still have a couple of clients who
are building USB video capture devices that are not UVC compliant. The
HCK rules for USB video capture devices require that they operate
correctly using usbvideo.sys and nothing else.
Until recently, we just submitted those devices as "unclassified". If
the HCK is going to force its autodetection, then these devices simply
cannot be WHQLed.
