Abstract

An apparatus such as a mobile telephone or a network card is described. In one implementation, the apparatus comprises a first functional module, a second functional module and a hub circuit. The hub circuit includes a first downstream port connectable to the first functional module, a second downstream port connectable to the second functional module and an upstream port adapted to be coupled to an external device. The hub circuit is configured to couple the upstream port with at least one of the first and second downstream port. Moreover, the hub circuit comprises a switching mechanism adapted to selectively couple the first downstream port internally within the hub circuit with the second downstream port to enable a data transfer between the first functional module and the second functional module.
