Hi! I'd have an Exibel snakescope TF2808 which dont make any picure on Linux. It worked ok on windows, but I do not have windows installed any longer. I do not think there have happened something to the camera meanwhile, I'd think the camera is OK. The driver seems to be ok too: (part of messages) Apr 25 19:43:16 sigmund-laptop kernel: [ 20.967903] gspca: main v2.6.0 registered Apr 25 19:43:16 sigmund-laptop kernel: [ 21.214190] gspca: probing 093a:2620 Apr 25 19:43:16 sigmund-laptop kernel: [ 21.287398] gspca: probe ok Apr 25 19:43:16 sigmund-laptop kernel: [ 21.287416] gspca: probing 093a:2620 Apr 25 19:43:16 sigmund-laptop kernel: [ 21.287431] gspca: probing 093a:2620 Apr 25 19:43:16 sigmund-laptop kernel: [ 21.287457] usbcore: registered new interface driver pac7311 Apr 25 19:43:16 sigmund-laptop kernel: [ 21.287462] pac7311: registered I'd have tried tvtime and xawtv as viewing application, same result on both; blank screen and various error messages. tvtime comes up with an blue screen "no signal","Frames too short from pac7311" and "cannot open capture device /dev/video0". xawtv started from an terminal outputs this and hangs: sigmund@sigmund-laptop:~$ xawtv -device /dev/video0 This is xawtv-3.95.dfsg.1, running on Linux/i686 (2.6.31-20-generic) xinerama 0: 1400x1050+0+0 WARNING: No DGA direct video mode for this display. /dev/video0 [v4l2]: no overlay support v4l-conf had some trouble, trying to continue anyway Warning: Missing charsets in String to FontSet conversion Warning: Cannot convert string "-*-lucidatypewriter-bold-r-normal-*-14-*-*-*-m-*-iso8859-*, -*-courier-bold-r-normal-*-14-*-*-*-m-*-iso8859-*, -gnu-unifont-bold-r-normal--16-*-*-*-c-*-*-*, -efont-biwidth-bold-r-normal--16-*-*-*-*-*-*-*, -*-*-bold-r-normal-*-16-*-*-*-m-*-*-*, -*-*-bold-r-normal-*-16-*-*-*-c-*-*-*, -*-*-*-*-*-*-16-*-*-*-*-*-*-*,*" to type FontSet Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to type FontStruct Warning: Missing charsets in String to FontSet conversion Warning: Cannot convert string "-*-lucidatypewriter-bold-r-normal-*-14-*-*-*-m-*-iso8859-*, -*-courier-bold-r-normal-*-14-*-*-*-m-*-iso8859-*, -gnu-unifont-bold-r-normal--16-*-*-*-c-*-*-*, -efont-biwidth-bold-r-normal--16-*-*-*-*-*-*-*, -*-*-bold-r-normal-*-16-*-*-*-m-*-*-*, -*-*-bold-r-normal-*-16-*-*-*-c-*-*-*, -*-*-*-*-*-*-16-*-*-*-*-*-*-*, *" to type FontSet ioctl: VIDIOC_G_STD(std=0xb789b1d000971326 [PAL_B1,PAL_G,PAL_D,PAL_M,PAL_N,NTSC_M,SECAM_B,SECAM_D,SECAM_G,SECAM_K,?ATSC_8_VSB,(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null)]): end of xawtv output syslog also came up with two new lines: Apr 25 20:30:22 sigmund-laptop kernel: [ 2848.327067] gspca: usb_submit_urb [0] err -28 Apr 25 20:30:23 sigmund-laptop kernel: [ 2848.607073] gspca: usb_submit_urb [0] err -28 Tried an Creative Live! cam on the same machine and it works ok. sigmund@sigmund-laptop:~$ uname -a Linux sigmund-laptop 2.6.31-20-generic #58-Ubuntu SMP Fri Mar 12 05:23:09 UTC 2010 i686 GNU/Linux I do not have any idea nor what to do now, nor how the error could be further traced down.
