 * This driver is written by <NAME> and <NAME>.

 * Ideas are taken from bttv driver by <NAME>, <NAME> &

 * Updates to driver completed by <NAME>
 *
 *
 * 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
