USB specification for supporting Zoom

Description
I am planning to develop a conference speakerphone, and the device has below buttons :

  1. Mic mute/unmute
  2. Hook button (to answer or hang up a call)
  3. Volume Up/Down

As I know, the device must support USB HID V1.2 and USB Audio Class V1.0.
Is there else USB protocol required to support for Zoom ?

Thanks

Hey @coryhuang0619,

Thanks!
