Abstract:
An electronic device includes a universal serial bus (USB) interface therein. This USB interface is configured to support at least first and second different USB interface standards. These different interface standards are selected by the electronic device in response to comparing a voltage level of a signal provided to said USB interface relative to a reference voltage generated within the electronic device. The signal provided to the USB may be a power supply signal, the first USB standard may be a USB 2.0 interface standard and the second USB standard may be an inter-chip USB interface standard.
