24 | * Let's call the version 0.... until compression decoding is completely | |

26 | * | |
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. | |
c5f48367 TM |
39 | * - Add audio on endpoint 3 for nt1004 chip. |
40 | * Seems impossible, needs a codec interface. Which one? | |
483dfdb6 TM |
41 | * - Clean up the driver. |
42 | * - optimization for performance. | |
43 | * - Add Videotext capability (VBI). Working on it..... | |
44 | * - Check audio for other devices | |
45 | * | |
