Abstract:
1. A switching system for incorporation within a device, comprising: a first port for coupling to a USB port of the device, wherein the USB port is configured to couple to a first USB device; a second port for coupling to an embedded device within the device, wherein the embedded device includes low power logic for enumeration with the first USB device using only power provided by the first USB device; a third port for coupling to device logic of the device, wherein the device logic is configured to perform functionality of the device, wherein the device logic is further configured to perform enumeration of the device with the first USB device and wherein the device logic is further configured to generate one or more switching signals; a switch, wherein the switch is coupled to the first port via a first connection, wherein the switch is coupled to the second port via a second connection, wherein the switch is coupled to the third port via a third connection, wherein, in a first position, the switch is configured to connect the first port to the second port, and, in a second position, the switch is configured to connect the first port to the third port and wherein each connection comprises a DP signal line and a DM signal line between the switch and the respective port; switch logic, wherein the switch logic is configured to control a position of the switch, wherein the switch logic is configured to:
