neilstreet6036 Posted August 22, 2014 Report Share Posted August 22, 2014 Hi, I have 4 arduino mega's running through a usb hub. When i try and add them through the add arduino script, it returns a 'cannot communicate with device' error. If i plug only one arduino into the hub at any time i can communicate with each. Each has its own tty device assinged on the raspberry. pi Any ideas please? Thanks, Neil. Link to comment Share on other sites More sharing options...
