First Claim
Patent Images
1. A charging hub comprising:
- a Universal Serial Bus (USB) interface including differential data connectors, a VBUS connector, and a USB-ID connector;
an upstream USB port that operably couples to the USB interface;
a control circuit that is not configured to support USB On-The-Go-compatible Host Negotiation Protocol and that is operably coupled to the USB-ID connector and configured to transmit an identifier via the USB-ID connector to prompt a USB device in function mode to serve as a USB host.

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.
