CueCat driver for Linux

Linux device driver for CueCat barcode readers that supports multiple PS/2 CueCats on either the keyboard port, mouse port (without disabling the mouse) or USB port through a PS/2 -> USB adapter, or native USB CueCats. A standalone application that doesn't require the driver and also reads barcodes from a CueCat connected to a serial port through a homemade PS/2 -> serial converter is included as well. The driver separates CueCat barcode scancodes from normal keyboard or mouse scancodes, decode the barcodes, performs error-checking on them and send them in clear text through a normal character device file. NOTE : the company that created the CueCat has disappeared. CueCat readers are no longer produced or distributed.
