I have all power connections correct to my board and my computer sees the USB when I plug it up. When I introduce 24 volt to the board to power my motors the board disconnects the USB to the computer and the computers gives me an error. Has anyone ran into this issue? Power input 24.35 volts on a True RMS meter, tried with external 5volt power and USB power same result.
Once power is turned on the Computer shows USB not recognized, but is seen pre 24volt power up.
Once powered up, USB com drops and then shows Unknown USB Device (Device Descriptor Request Failed).
