Abstract
A device for detecting an interface voltage of a Universal Serial Bus (USB) interface. The device includes first and second voltage level indicators, and first and second control circuits. The first control circuit receives the interface voltage to generate a first control signal and drive the first voltage level indicator when the interface voltage level is less than a first voltage level. The second control circuit receives the interface voltage to generate a second control signal and drive the second voltage level indicator when the interface voltage level exceeds a second voltage level.
