A controller for use in an optical storage device is provided. The controller includes a block decoder/encoder for processing data to and from a media of the optical storage device. An ATAPI interface is also provided and is configured to process data and control signals for selectively communicating data to and from the optical storage device during operation in an ATAPI mode. Universal serial bus (USB) logic is configured to process data and control signals for selectively communicating data to and from the optical storage device during operation in a USB mode. The USB logic is configured to utilize data transfer control logic implemented by the ATAPI interface. Accordingly, the one controller can be integrated into either an external peripheral device that communicates over a USB connection in the USB mode, or into an internal peripheral device that communicates over an IDE connection in the ATAPI mode. The optical storage device can be any type of optical storage device, such as, for example a CD-RW, a CD-ROM, a CD-R, a DVD, and the like. Further, the optical storage device can be in the form of an internal or external peripheral device.
