Eyewear having a high-speed wireless transceiver, including a processor having a high-speed interface for communicating high-speed communications and a low-speed interface for communicating low-speed communications. The high-speed interface is disabled to have no standby current and only the low-speed interface is used when only low-speed communications are needed to save current. When communications are received via the high-speed wireless transceiver, only the low-speed interface is initially used, and the high-power interface is later used if necessary. The high-speed interface can be a high-speed universal serial bus (USB) interface, and the low-speed interface can be a universal asynchronous receiver-transmitter (UART) interface. A USB hub is controlled by the processor to selectively enable the USB interface.
