Abstract: A control circuit (comprising, for example, a part of a charging hub for a portable electronic communications device) that is not configured to support USB On-The-Go-compatible Host Negotiation Protocol is operably coupled to a USB-ID connector and is configured to transmit an identifier via that USB-ID connector to prompt a USB device in function mode to serve as a USB host. A locally-available power supply can then serve to provide power to that USB device notwithstanding the latter's role as the host.

Abstract: A communications system may include a communications device including a first Bluetooth transceiver. The first Bluetooth transceiver may comprise a clock. The first Bluetooth transceiver may be capable of scanning a plurality of different operating frequencies for a pairing request based upon the clock. The communications device may further include an output device coupled with the Bluetooth transceiver and capable of outputting data associated with the clock via a communications path different than Bluetooth. The system may also include a mobile communications device including an input device capable of receiving the clock data from the output device via the communications path, and a second Bluetooth transceiver coupled with the input device and capable of generating the pairing request based upon the received clock data.
