I have a Focsurite 2i2 interface. Been using it for 5 months now but now all of a sudden when i plug the interface to my device the interface powers on and all the light keeping flickering on and off continuously
Well I would say it is broken. If you have only had it 5 months and you are in the UK or EU then it will still be under the manufacturer’s guarantee, so contact them and get a replacement or repair.
