Abstract: Data transfer devices as well as methods of interfacing, configuring, and using the same are disclosed. Data transfer devices described herein allow a proper communication interface to be mounted on an input device, e.g., a scanner, connected to the data transfer device, enabling communication between the input device and a host device.
