Abstract

A bridge device for connecting a USB 3 host device with a plurality of downstream, non-USB 3 mass storage devices, such as SATA or PATA devices. The bridge device comprises an embedded hub having a plurality of internal USB 3 devices. The internal USB 3 devices do not have a physical USB 3 interface. The bridge device also has at least one downstream physical non-USB 3 device, to which a mass storage device may be attached. The internal USB 3 devices enable the host device to be presented with a plurality of USB 3 devices. This, in turn, allows transfer to the plurality of downstream physical non-USB 3 devices, via the internal USB 3 devices at an increased rate. The bridge may also include a downstream physical USB 3 interface. This can allow multiple bridge devices to be connected together in a cascade.
