- * GPL/Linux driver written by Patrick Boettcher <patrick.boettcher@desy.de>
- *
- * This driver is "hard-coded" to be used with the 1st generation of

- *
- * The driver works also with QAM64 DVB-C, but had an unreasonable high
- * UNC. (Tested with the Air2PC ATSC 1st generation)
- *
- * You'll need a firmware for this driver in order to get it running. It is
