Hello,
I m using the usb cable with the power usb power supply that was in the box. When I turn it on, only the red ligt above the screen on the receiver is turning on and nothing else. The only way to turn it on is to use my Stomp 9v power adapter, and then it stays on, while connected to the usb power supply. Am I missing something? Do i need to buy a separate power supply? I thought the USB one in the box is supposed to be the power supply.
