Thanks for review!
Here is what's new in this V2: - Split the patchset into a more sensible series.
This patchset adds support for the Insertion Control for BADD devices (subset of UAC3).
This control is only pressent in the HEADSET ADAPTER BADD profile. The USB interrupt pipe shall be present for this profile so the status pipe creation should also happen for BADD devices.
Also, the bi-directional type codes have been defined so they can be used as inferred values for the Input and Output terminals for this adapter profile.
