Abstract
A USB hub module which is configured to enable a vehicle's embedded USB host 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 providing USB OTG controllers or additional vehicle wiring or inhibiting functionality of consumer devices connected the module while one consumer device connected to the module operates in USB host mode. Preferably, the module is configured so that no additional cabling or hardware changes are required to the head unit. The module can be employed between the embedded USB host, USB hub and at least one consumer accessible USB port. When 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 embedded USB host.
