Abstract
A method to enable a vehicle's embedded USB Host system to connect to multiple mobile devices through a USB Hub, regardless of whether the mobile devices are configured to act as USB Hosts or USB Devices, without OTG controllers or additional vehicle wiring, or inhibiting the functionality of any consumer devices connected to the same USB Hub. Preferably, the method is configured to provide that no additional cabling is required, and no hardware changes are required to be made to the HU. The method can be employed between a vehicle's embedded USB Host, USB Hub and at least one consumer accessible USB port. In the case where the consumer device is acting as a USB Host, signals between the consumer device and the vehicle's embedded USB Host are processed through a USB bridge, thereby rendering the consumer device compatible with the vehicle's embedded USB Host.
