This patch adds an additional device ID to the cp2101 USB serial
driver. This device is a Gemalto Prox-PU or CU contactless card reader
(ISO14443-A/B and Mifare). The reader is a standard Gemalto serial
proximity reader using the Gemalto Block Protocol (see reader's
documentation) bundled with a built-in CP2102 for serial/USB
conversion.
