Abstract
An interface device between, and a method for providing data from, one of a plurality of optical or magnetic media reader devices to a host is disclosed. The interface device comprises first and second input ports, each port being connectable to a selected media device. The device also comprises means for automatically identifying the type of media device connected to each of the ports by sequentially sampling control or data signals therefrom. It also includes means for determining when an identified media device is active by sampling control or data signals from each port that has an identified media device connected thereto.
