Hi, I'm having a rather bizarre issue. My zynthian box only works when it is powered by my computer, and never works when it is powered by a USB power supply.
I tried dozens of times, with different power supplies (1A and 2.4A) and different computers (laptop and desktop), same result. At the engine screen, after pressing SELECT to select an engine, if it is powered by a USB power supply it freezes (well the wavelet gets animated forever). But if it is powered by a computer, it passes to the next screen in a fraction of second.
Any idea is very welcome!
