[Linux-uvc-devel] Logitech Quickcam Notebook Pro
Hello, I got the latest version from subversion about an hour ago. It compiled and installed fine, but it doesn't seem to recognize my quickcam beyond knowing it's a UVC device. Here are the relevant lines from dmesg: [17206689.184000] usb 4-4.2: new high speed USB device using ehci_hcd and address 11 [17206689.432000] usb 4-4.2: configuration #1 chosen from 1 choice [17206689.432000] uvcvideo: Found UVC 1.00 device unnamed (046d:08cb) Udev created a /dev/video and /dev/video0, but camorama says could not connect to video device (/dev/video0). Is there a simple way to fix this, or is the support simply unwritten? Thanks in advance, Aaron Miller ___ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel

Hi Aaron, I got the latest version from subversion about an hour ago. It compiled and installed fine, but it doesn't seem to recognize my quickcam beyond knowing it's a UVC device.

Is there a simple way to fix this, or is the support simply unwritten? Camorama is at fault. It only supports the deprecated V4L1 interface, while the driver implements V4L2.

Re: [Linux-uvc-devel] QC Pro 5000 with mythphone
Hi Richard, Thanks for the report. I committed a fix to SVN for Linux 2.6.15 and earlier. Thanks Laurent. Compilation error fixed. This has nothing to do with the Linux UVC driver. The audio device is handled by the USB audio ALSA driver. Thoralf Schulze mentionned a way to fix your problem. Thanks Thoralf. I have not tried the index fix yet, but it seems like a good idea. If you want help, you'll have to tell us what goes wrong with mythphone :-) Well, it does not work :) I tried it again after recompiling and loading the latest version of uvcvideo. Evidently, it tries a few formats, but it does not display any video. I am not sure if audio is working. It should display a local video window when the application starts, but I do not see anything. mythphone has a few settings for capture resolution (160x120, 128x96, 704x576, 640x480, 352x288, 320x240, 176x144). It does not seem to matter which one I select--still no video. I have the QC Pro 5000 connected to a USB 1.1 port so I have been trying the smaller resolutions. Does mythphone report any error ? Try to start it in a console, it might use stdout/stderr for debugging. You can also set the trace level to 65535 to get more information from the driver. Have a look at the kernel log then to see if something goes wrong.

Re: [Linux-uvc-devel] Hi, how could I help?
I did what you suggested. Attached is the resulting dmesg output with
trace raised to 65535.
Oops, my bad, the patch I sent you was wrong. Could you please try the
attached patch ?
Thanks.
Best regards,
Laurent Pinchart

Re: [Linux-uvc-devel] Logitech Quickcam Notebook Pro
Udev created a /dev/video and /dev/video0, but camorama says could not connect to video device (/dev/video0). Is there a simple way to fix this, or is the support simply unwritten? Camorama is at fault. It only supports the deprecated V4L1 interface, while the driver implements V4L2. I also tried xawtv. It had no problem connecting to /dev/video0, however it displayed a black screen. --Aaron Miller ___ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
