**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 ---
