Hi, I have a USB audio device. The driver is composed of a USB driver that is loaded when the device is plugged in. It creates a virtual bus which loads the WaveCyclicPCI driver. When I run WHQL on the audio device, the tests pass and the audio driver is certifiable. However, how can pass the bus driver component? I don't see any WHQL tests for it. Also, is it possible to combine both drivers?
