USB was initally a slow transfer or connection. High volumes of data required for video might overload the transfer rate. If you don’t have the software or drivers, you don’t just get this by plugging in a USB without them. There are different standards for video and sound, as well as documents or pictures. Without the correct software and/or drivers a computer cannot just product or translate the files.
USB is not a sound device. USB is not a video device. USB is not always a storage device, or just a power device. USB is a standard connection. Everything else depends on the cable or the software.
Well of course, except that in this case the USB-C port on the computer or expansion card also needs a bit of extra electronics behind it. But, that’s not the point. The point is why is the hardware / software ubiquitous on laptops starting a few years ago, but desktops were much slower to catch up, and most USB-C expansion cards STILL don’t have the capability...
