TESTING CURRENT DRAW CAPACITY FROM AN UNKNOWN USB SUPPLY

Methods, systems, and computer readable media can be operable to facilitate a testing of an unknown USB supply that is connected to a CPE (customer premise equipment) device to determine a current draw capacity of the USB supply. The CPE device may test the USB supply to determine whether the USB supply is capable of supplying a predetermined current. If the determination is made that the USB supply is not able to supply the predetermined current, an end-user may be instructed to plug an alternative PSU (power supply unit) into the CPE device, wherein the alternative PSU is capable of supplying the predetermined current to the CPE device. The CPE device may output an indication that an alternative PSU should be used via a graphics output to a display device through an HDMI (high-definition multimedia interface) connection or via an LED indication using one or more LEDs at the CPE device.
