Hello guys,

Has anyone ever got this to working under any Linux distro, including Fedora?

I have just plugged it in and I get this on dmesg:

[ 1365.932522] usb 2-1.1: new full-speed USB device number 26 using
ehci_hcd

Device is recognized since it appears in lsusb:

[skorzen@g62 ~]$ lsusb | grep DVC
Bus 002 Device 026: ID 07d0:0004 Dazzle DVC-800 (PAL) Grabber

However, I cannot make it work (my goal is to capture video from a camcorder).
I've tried using cheese for this, but it just crashes and ABRT launches for me to fill a bug.

Any ideas?

Best regards,

Ondrej Zary

Please include the output of "lsusb -v" for this device (run the command as root).

Hi,

Also please output lsmod with your device plugged and the list of your installed modules (do you know how to do this?)

I may be wrong, but this device should be supported by usbvision module.

Thanks,
Ezequiel.

Hi there,

Is this information sufficient? Did lsmod, and the same but grepping 'usbvision' module.

I may be wrong, but this device should be supported by usbvision module.

The log show that usbvision module is loaded but fails to set altsetting to 1. Probably because the device has two interfaces (note that the driver is also initialized twice).

Yes, I've just noticed this.

Perhaps, you could try using vlc and/or mplayer (instead of cheese) and also try to use explicit device, i.e. /dev/video1 and/or /dev/video2.

But if the driver fails to set alternate setting, then it will never work, right?

Hope this helps,
Ezequiel.

Hello guys,
Has anyone ever got this to working under any Linux distro, including Fedora?
I have just plugged it in and I get this on dmesg:
[ 1365.932522] usb 2-1.1: new full-speed USB device number 26 using

Device is recognized since it appears in lsusb:
[skorzen@g62 ~]$ lsusb | grep DVC
Bus 002 Device 026: ID 07d0:0004 Dazzle DVC-800 (PAL) Grabber
However, I cannot make it work (my goal is to capture video from a camcorder).
I've tried using cheese for this, but it just crashes and ABRT launches for me to fill a bug.

Any ideas?
Please include the output of "lsusb -v" for this device (run the command as root).
Here it is, mate. Thanks for your cooperation.

Best regards,

Can you test this patch? It should make the driver ignore the second interface with no endpoints.

Hello guys,
Has anyone ever got this to working under any Linux distro, including Fedora?
I have just plugged it in and I get this on dmesg:

Device is recognized since it appears in lsusb:

However, I cannot make it work (my goal is to capture video from a camcorder).
I've tried using cheese for this, but it just crashes and ABRT launches for me to fill a bug.

Any ideas?
Please include the output of "lsusb -v" for this device (run the command as root).
Here it is, mate. Thanks for your cooperation.
