This rule makes it easier to use CCD devices when the raiden module can't be installed for some reason. The rule informs the usbserial module that it should handle anything that looks like a simple serial port for any CCD compatible USB devices. The install script now detects failure when building and installing the raiden module and offers the --fallback option in that case.
