20120311203 | USB SWITCH WHICH ALLOWS PRIMARY USB CONNECTION IN RESPONSE TO USB SIGNALING - System and method controlling connectivity within a device. A device may be coupled to a host device. In response to the coupling, low power logic (e.g., an embedded device) of the device may be coupled to the host device. The low power logic may perform enumeration with the host device using only power provided by the host device. The low power logic may also charge a battery of the device using power provided by the host device. Device circuitry of the device may provide a signal for coupling to the host device. In response, the device circuitry may be coupled to the host device and may perform device enumeration with the host device. | 12-06-2012 |
