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.
