I´ve got my Quantum for over a year and working flawless. I needed to format my PC,which is a 8700k, 32gb Ram, with a Gigabyte Designare MB. I installed the latest version of Universal control, connect the interface and nothing, its like it does not exist. Fixed Red Start Button, no thunderbolt light, no devices on UC. All the drivers are up to date. Don´t know what more to do.
