UR242 not powering up. PLEASE HELP

I’m using a Steinberg UR242 which I haven’t used with my laptop for a while. I have it plugged in via USB now and it’s not turning on. Totally dead. I’ve tried switching out USB cables, no dice. I only have two cables and neither of them work. Are my USB ports dead or underpowered, am I using old USB 1.0 cables and not aware of it, or is the unit just totally dead?

Any advice would be much appreciated. Using an early 2013 Macbook Pro.


My UR242 is not USB powered, you need to plug it into the electric mains for it to function!!!
