Abstract:
1. A method for powering a mobile device and charging a battery in the mobile device comprising: detecting a universal serial bus (USB) bus voltage at a USB interface configured to be connectable to a USB host; measuring passage of a pre-determined amount of time, the pre-determined amount of time starting upon the detecting of the USB bus voltage; allowing the powering of one of the mobile device, the charging of the rechargeable battery, or, both the mobile device and the charging of the rechargeable battery during the pre-determined amount of time; detecting receipt of a device suspend signal during the pre-determined amount of time, and then disabling the use of the USB bus voltage and a current to power the mobile device and charge the battery; and if an enumeration is not completed before the pre-determined amount of time has expired, then disabling the use of the USB bus voltage and the current to power the mobile device and charge the battery; wherein the USB cable is connected between mobile electronic device and the USB host to transmit current and voltage from the USB port.
