USB cameras require a host computer because they are 'dumb cameras' that send UVC streams, which can be in various formats (uncompressed, H.264, H.263, or ME2 transport streams). Unlike HDMI or SDI cameras, USB cameras cannot be directly switched without a computer to interpret the streams. This is why hardware switchers with USB inputs are rare—USB cameras need a computer to function, and multiple USB cameras with identical identifiers can cause switching difficulties. Solutions include using a dedicated computer with software like OBS or V-Mix, or using NDI (Network Device Interface) to convert USB cameras to network streams that can be switched by hardware devices like the Roadcaster Video.
