Hi,

I seem to have a similar problem on a USB audio driver (MSVAD based)
How do I go about making the category changes you describe to get it to 
show up?

Thanks

Category was KSCATEGORY_AUDIO - I was 
using KSNODETYPE_xxx for the KSPIN_DESCRIPTOR::Name field.

After changing the bridge pin category to KSNODETYPE_LINE_CONNECTOR (for 
example) I can see my audio device!

Thanks,
Nick
