Hi all, I am using Ubuntu 8.10 and a Crative VF0540 Webcam. Which identifies isself as:
$ dmesg [26238.642082] uvcvideo: Found UVC 1.00 device Vimicro USB 2.0 PC Camera (Venus) (0ac8:3420) [26238.642675] uvcvideo: No valid video chain found. The problem is: uvcvideo: No valid video chain found. The funny thing is, It worked before (about a month ago.) But back than I did not investigate anything - it just worked. Now it does not work anymore. I constantly updated my Ubuntu. Booting an old kernel did not do it. On a other Ubuntu 8.10 which is almost the same it doesn't work either. Funny is also that 0ac8:3420 is listed as working on http://linux-uvc.berlios.de/. I downloaded the latest uvcvideo-f5c337ded781.tar.gz from 02. Feb 2009, compiled is and run it (see listings below). No help. I got no Idea any more, I would appreciate any help. I look forward to your answers. ruena $modinfo uvcvideo filename: /lib/modules/2.6.27-11-generic/kernel/drivers/media/video/uvc/uvcvideo.ko version: v0.1.0 license: GPL description: USB Video Class driver author: Laurent Pinchart <[email protected]> srcversion: 413A0ECBDFDB0F4525A35E3 alias: usb:v*p*d*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v1C4Fp3000d*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v19ABp1000d00*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v19ABp1000d01[0-1]*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v19ABp1000d012[0-6]dc*dsc*dp*ic0Eisc01ip00* alias: usb:v18CDpCAFEd*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v17EFp480Bd*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v174Fp8A33d*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v174Fp8A31d*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v174Fp5931d*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v174Fp5212d*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v0E8Dp0004d*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v05E3p0505d*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v05ACp8501d*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v058Fp3820d*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v046Dp08C7d*dc*dsc*dp*icFFisc01ip00* alias: usb:v046Dp08C6d*dc*dsc*dp*icFFisc01ip00* alias: usb:v046Dp08C5d*dc*dsc*dp*icFFisc01ip00* alias: usb:v046Dp08C3d*dc*dsc*dp*icFFisc01ip00* alias: usb:v046Dp08C2d*dc*dsc*dp*icFFisc01ip00* alias: usb:v046Dp08C1d*dc*dsc*dp*icFFisc01ip00* alias: usb:v045Ep0723d*dc*dsc*dp*ic0Eisc01ip00* alias: usb:v045Ep00F8d*dc*dsc*dp*ic0Eisc01ip00* depends: usbcore,videodev,v4l1-compat vermagic: 2.6.27-11-generic SMP mod_unload modversions 586 parm: nodrop:Don't drop incomplete frames (uint) parm: quirks:Forced device quirks (uint) parm: trace:Trace level bitmask (uint) $ ls -l /lib/modules/2.6.27-11-generic/kernel/drivers/media/video/uvc/uvcvideo.ko -rw-r--r-- 1 root root 83156 2009-02-02 23:07 /lib/modules/2.6.27-11-generic/kernel/drivers/media/video/uvc/uvcvideo.ko $ uname -a Linux core 2.6.27-11-generic #1 SMP Thu Jan 29 19:24:39 UTC 2009 i686 GNU/Linux $ sudo lsusb -vv -d 0ac8:3420 Bus 004 Device 016: ID 0ac8:3420 Z-Star Microelectronics Corp.
