USB Video class Composite Device

[Ismael_dz]

Hello community! I got a question. For a UVC composite device with Color and sensor Camera, do I need more than 1 Video Control Descriptor? Im not sure If I simply can add the inteface and endpoint for the second camera and still use one video control of if it is needed to use two video control descriptor.

Hello, Ismael_dz 

Do you mean UVC class device streaming two videos simultaneously? UVC class allows many video sensors (sources) in one device but streaming just a single one at a time. Selector interface allows switching among sources. But there are no means to define two or more simultaneous video streams. That's for standard UVC device, which is recognized by built-in Windows driver.
