Embodiments of the invention include a bus bridge that is capable of communicating with more than one MSC device coupled to it. In some embodiments, the bridge includes a processor that translates different routing numbers received from the bus into different addresses and routing numbers for devices connected to the bridge. The bridge masks the fact that multiple MSC devices are coupled to it by reporting to the host that only a single device having multiple LUNs are coupled to the bridge.

Enabling multiple ATA devices using a single bus bridge

ATA devices, such as mass storage units, have increasingly larger storage sizes that use larger configuration register sizes. A command block format allows the USB/ATA bridge circuit to be used with ATA devices with larger registers and at the same time operates with earlier ATA command block formats.

ATA device control via a packet-based interface

A serial to parallel port signal converter for interconnection between a hosts utilizing Uniform Serial Bus communications protocols and a peripheral device uses IEEE 1284 complaint communications protocol. The signal converter appears to the host as a fully compliant bi-directional USB device, and to the peripheral device as a fully compliant IEEE 1284 host.
