I have a Berringer U-Phoria UM2 audio interface, I use it to amplify a microphone input and split it between a headphone amp and a transmitter. I works fine when the USB cable is plugged into a computer, but fails to work at all when I try to power it from a USB outlet of a phone charger or power strip?
Any thoughts on how I can make it take power from the non computer USB source?
