Claim 7:
8. A device for use in testing a capacity of a universal serial bus (USB) supply comprising:
a memory;
a processor coupled to the memory storing one or more instructions that when executed by the processor cause the device to:
initiate a pulsed current draw capacity test of a pulsed current draw by a current load source of the device from the USB supply provided through a USB port of the USB supply to test a capacity of the USB supply to supply a predetermined current through the USB port to the device needed during normal operation of the device;
generating a predetermined current load to apply a pulsed current load, at a duration to prevent an overcurrent trip from fully activating, to the USB supply providing power to the device through the USB port during the pulsed current draw capacity test to test the capacity of the USB supply to provide the predetermined current from the USB port to the device during normal operation of the device, wherein the pulsed current load is generated by the current load source of the device by periodically removing the predetermined current load, and wherein the current load source progressively increases the pulsed current draw from the USB supply by the device by adding more functions in a controlled manner to generate the pulsed current load applied by the current load source to the USB supply;
determine whether the USB supply is capable of supporting the pulsed current load applied by the current load source to the USB supply through the USB port to provide the predetermined current to the device during the normal operation of the device; and
output a notification when the determination is made that the USB supply is not capable of supporting the pulsed current load applied by the current load source to the USB supply through the USB port to provide the predetermined current from the USB supply to the device during the pulsed current draw capacity test, wherein the notification includes an instruction to plug an alternative power supply into the device.
