I have an idea. USB singals are differential singals and they look the same as CAN-bus signals, even if they are USB signals.
Is it possible to use CANopen protocol to transfer USB signals to other devices? For example, if I connecting the USB differential cabels like this simple "hub". I borrow this picture. I know that this is not how a USB hub working, but it's just for illustrate the idea that CANopen can be used with USB signals? Or does it?
What is the most commonly protocol for transmitting messages in USB?
