27 * This driver is written by Jose Ignacio Gijon and Joerg Heckenbach.
28 * It was based on USB CPiA driver written by Peter Pregler,
29 * Scott J. Bertin and Johannes Erdfelt
30 * Ideas are taken from bttv driver by Ralph Metzler, Marcus Metzler &
31 * Gerd Knorr and zoran 36120/36125 driver by Pauline Middelink
32 * Updates to driver completed by Dwaine P. Garden
33 *
34 *
35 * TODO:
36 * - use submit_urb for all setup packets
37 * - Fix memory settings for nt1004. It is 4 times as big as the
38 * nt1003 memory.
39 * - Add audio on endpoint 3 for nt1004 chip.
40 * Seems impossible, needs a codec interface. Which one?
41 * - Clean up the driver.
42 * - optimization for performance.
43 * - Add Videotext capability (VBI). Working on it.....
44 * - Check audio for other devices
