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