+ * This driver is written by Jose Ignacio Gijon and Joerg Heckenbach.
+ * It was based on USB CPiA driver written by Peter Pregler,
+ * Scott J. Bertin and Johannes Erdfelt
+ * Ideas are taken from bttv driver by Ralph Metzler, Marcus Metzler &
+ * Gerd Knorr and zoran 36120/36125 driver by Pauline Middelink
+ * Updates to driver completed by Dwaine P. Garden
+ *
+ *
+ * TODO:
+ *     - use submit_urb for all setup packets
+ *     - Fix memory settings for nt1004. It is 4 times as big as the
+ *       nt1003 memory.
+ *     - Add audio on endpoint 3 for nt1004 chip.  Seems impossible, needs a codec interface.  Which one?
+ *     - Clean up the driver.
+ *     - optimization for performance.
+ *     - Add Videotext capability (VBI).  Working on it.....
+ *     - Check audio for other devices
