Thank you canek (and walt, james, and eroen) but I didn't make clear the |
| 22 |
level of my ignorance. I have never used a webcam, but I recently |
| 23 |
became a grandfather so figured I should learn. I must need a driver |
| 24 |
for the camera. According to lsusb I have |
| 25 |
|
| 26 |
Bus 001 Device 004: ID 0c45:646b Microdia |
| 27 |
(the 400 line verbose output is at the end of this msg). |
| 28 |
|
| 29 |
But I get no hits on google for that number (there are some close) |
| 30 |
gentoo-wiki.info lists several webcams but not mine then ends with |
| 31 |
|
| 32 |
Other |
| 33 |
|
| 34 |
If you can't identify the make or model or your webcam, try these |
| 35 |
drivers: |
| 36 |
|
| 37 |
media-video/gspcav1: supports many webcams based on various |
| 38 |
chipsets. List of supported devices at |
| 39 |
http://mxhaard.free.fr/spca5xx.html |
| 40 |
|
| 41 |
media-video/linux-uvc: supports many webcams following the UVC |
| 42 |
specification. List of supported devices at |
| 43 |
http://linux-uvc.berlios.de. A specific viewer luvcview is |
| 44 |
available. |
| 45 |
|
| 46 |
From the list at linux-uvc.berlios.de I see that 0c45 is Sonix |
| 47 |
Technology and the model number closest to mine 6409 is for a |
| 48 |
(different) dell laptop so I am guessing I should try |
| 49 |
media-video/linux-uvc. |
| 50 |
|
| 51 |
But, as I mentioned, I am a complete novice with webcams and wonder if I |
| 52 |
am way off base here. Is the above the right path to follow? |
| 53 |
|
| 54 |
thanks, |
