 |
|
I can't get my webcam to work, it's a Trust Spycam 300s, which uses the stv680 module using xawtv:
| Code: | This is xawtv-3.94, running on Linux/i686 (2.6.13-ck8)
can't open /dev/video0: No such device
v4l-conf had some trouble, trying to continue anyway
v4l2: open /dev/video0: No such device
v4l2: open /dev/video0: No such device
v4l: open /dev/video0: No such device
no video grabber device available
|
While /dev/video0 is there for sure:
| Code: | ls video*

I've tried pretty much all of what I could find on the forum + google, so what could be the problem.... |

| by the way, I have several USB product working on the same port, like a printer (Epson 890), Digicam (PTP and Mass storage Nikon 4600), Bluetooth (Sitecom dongle thing) and Memory stick (Dell shitty 64 MB thing) so the problem should be somewhere in the v4l thing but I don't know where to look. |

With all those /dev/video* entries I would think they are remnants of the old static /dev system.
If you are using udev, which I hope you are, you can remove all the /dev/ nodes and let udev recreate only the ones you need.
(udevstart or reboot)
I think the default of udev is to use /dev/v4l/video*. Either try using /dev/video/video0 and/or make a symlink to this. | Code: | | ln -s /dev/v4l/video0 /dev/video0 |

Well, after some struggeling I got some kind of alien webcam of which nobody ever heard. This webcam worked fine with the spca5xx module, so I'm pretty convinced that my system is OK now for handling webcams (after some kernel rebuilds etc.).
It created /dev/v4l/video0 (to which the symlink of /dev/video0 pointed) and xawtv, gqcam, amsn etc all got it to work.
I'm no more using "hotplug" or "coldplug", just "usbd" and kernel 2.6.14-ck1 (CONFIG_VIDEO_DEV = m) with the spca5xx module (either by emerging or compiling the source from the website) .
I guess that the webcam I aimed to use (Trust Spycam 300s) is not supported by any driver/module available, since I tried all of them.
Is there anyone who has got this webcam to work? |

Can you post the relevant parts of
regarding your webcam.
Some of the sites I looked at suggested that the ov511 module works with that webcam.
Edit: My mistake. Looks ike it was Spacecam, not Spycam. I guess STV0680 drive IS what you need.
Have you tried using the pencam2 program without loading the stv0680 module, as suggested on the driver homepage? |

I'm quite sure it's not the stv680 module, I found this suggestion also but it referred to the Spycam300 instead of Spycam300s so that might explain why it does not work.
without loading the module:
| Code: | ./pencam2
pencam_open error: Cannot open camera. Are you sure it is connected to the computer? |
with loading the module:
| Code: | ./pencam2
pencam_open error: Cannot open camera. Are you sure it is connected to the computer? |
I guess I'm stuck here
edit:
what I didn't notice before (my fault) is that it is listed is "lsusb"
