Look at SEE ALSO in webcamd's > manpage... Hi Juergen, My Acer D250 netbook has a built-in cam (0c45:62c0) and I have an additional USB Philips SPC900NC. Both are supported by the webcamd drivers and show up in its man pages, in pwc.4 and uvc.4. But: 'supported' does also mean that you need some application to talk to them and it turned out that KDE's Kopete uses ioctl of v4l2 (and works with the 0c45:62c0) while Skype talks ioctl of v4l and does not work with the 0c45:62c0. The SPC900NC works nicely with Skype in both ways, either with the pwc.ko kernel mod or via webcamd with its pwc-driver. That's why I think that the man pages of webcamd are not enough, there should be a note about if v4l or v4l2 is awaited from the application; or we need some overall table describing the cams(...) from all webcamd drivers and the application which can be used. A side note: Hans, the above mentioned Philips SPC900NC shows up on plug-in as: Feb 2 08:11:07 current root: Unknown USB device: vendor 0x0471 product 0x0329 bus uhub2 but in pwc.4 as 0471:0320; the source itself v4l-dvb-abd3aac6644e/linux/drivers/media/video/pwc/pwc-if.c contains the correct value: $ fgrep 0329 v4l-dvb-abd3aac6644e/linux/drivers/media/video/pwc/pwc-if.c { USB_DEVICE(0x0471, 0x0329) }, /* Philips SPC 900NC PC Camera */ HIH matthias -- Matthias Apitz t +49-89-61308 351 - f +49-89-61308 399 - m +49-170-4527211 e - w http://www.unixarea.de/
