1. A computer-implemented method for switching between multiple sources of Universal Serial Bus (USB) signals, the method comprising:

  • examiningwhether a USB connector is physically coupled to a USB port of an electronic device by determining whether a power signal is presently being received at a first electrical contact within the USB port, andwhether an accessory is wirelessly coupled to a wireless transceiver of the electronic device by determining whether a physical connection is presently being maintained between a second electrical contact accessible through a housing of the electronic device and a third electrical contact accessible through a housing of the accessory;

    processing a first USB signal received at a first source,wherein the first source is the USB port or the wireless transceiver;

    determining that a second USB signal has been received at a second source,wherein the second source is whichever of the USB port and the wireless transceiver is not the first source; and

    executing a switching routine that enables the electronic device to sequentially receive the first and second USB signals at the first and second sources.
