Abstract
A system which is configured 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 the need to add or provide OTG controllers in the system or additional vehicle wiring, or inhibiting the functionality of any consumer devices operating in USB Device mode connected to a vehicle system Hub while another consumer device connected to the same Hub operates in USB Host mode. Preferably, the system is configured to provide that no additional cabling is required, and no hardware changes are required to be made to the HU. The system 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 bridge, thereby rendering the consumer device compatible with the vehicle's embedded USB Host.
