| 1198 | Since loading the firmware is often problematic when the driver is |

| 1201 | postponing it is that loading this firmware takes a long time (seconds) |
| 1202 | due to the slow i2c bus speed. So it will speed up the boot process if |
| 1203 | you can avoid loading the fw as long as the video device isn't used. */ |
