+ *
+ * TODO:
+ * - use submit_urb for all setup packets
+ * - Fix memory settings for nt1004. It is 4 times as big as the

+ * - 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
