I want to make an USB Isolator and have a gadget with an adruino on the Isolated side and my Pc on the other side. Both need a supply of 5V. I'am currently using a adum5000 combined with an adum3160 but can't get that USB-isolator to work propely. The Pc is either showing me nothing and if it connects to the arduino Matlab can't get access to the com port. Just currently I have found the exact same setup just with an adum4160.
