At the same time, we will let you know what are the ideal conditions to maximize this limit. Our goal is to determine how many Yoctopuce USB devices, either sensors or actuators, you can hope to get working properly on a machine. To give you a better and more useful answer, we have decided to test what works in real life. Unfortunately, life is not as simple: this naive reasoning does not take into account all constraints imposed by USB controllers. The USB specification plans for 127 device adresses on the USB bus, and it is tempting to deduce from this that you can connect up to 127 devices on a USB port.
