Hi, I have the problem that all webcam applications show only about half of the real picture (or even less).
I have tried - LUVCview - UCView - Skype - Cheese - MPlayer - Adobe Flash webcam access in webbrowser lsusb output is ID 0402:5606 ALi Corp. USB 2.0 Camera The cam is integrated into a Clevo M72SR notebook running Mandriva 2010.0 x86_64, but the issue exists also on Mandriva 2010.0 x86 and 2009.1 and 2009.0 etc... I updated the Bios 1 or 2 years ago and can't say for sure if the cam worked properly before, but I think it did... Can a Bios update bring up webcam malfunction? The default driver in Win 7 had similar problems and I had to download the Win 7 driver from Clevo website to get the cam working ftp://cftp.clevo.com.tw/M72xSR/Optional/Camera_all.zip After this driver is installed on Win 7, the webcam shows up as "Bison NB Pro" in the device manager and works flawlessly. I also noticed slow performance in Linux, the cam makes 2 - 5 fps, even at good exposure. dmesg output when cam is detected: usb 1-8: new high speed USB device using ehci_hcd and address 6 usb 1-8: New USB device found, idVendor=0402, idProduct=5606 usb 1-8: New USB device strings: Mfr=0, Product=1, SerialNumber=0 usb 1-8: Product: USB2.0 Camera usb 1-8: configuration #1 chosen from 1 choice uvcvideo: Found UVC 1.00 device USB2.0 Camera (0402:5606) input: USB2.0 Camera as /devices/pci0000:00/0000:00:03.3/usb1/1-8/1-8:1.0/input/ input15 dmesg output when accessing device: uvcvideo: device USB2.0 Camera requested null bandwidth, defaulting to lowest. uvcvideo: device USB2.0 Camera requested null bandwidth, defaulting to lowest. uvcvideo: device USB2.0 Camera requested null bandwidth, defaulting to lowest. uvcvideo: Failed to query (129) UVC control 2 (unit 5) : -110 (exp. 2). uvcvideo: Failed to query (129) UVC control 2 (unit 5) : -110 (exp. 2). uvcvideo: Failed to query (129) UVC control 3 (unit 1) : -32 (exp. 1). uvcvideo: Failed to query (129) UVC control 3 (unit 1) : -32 (exp. 1). uvcvideo: Failed to query (129) UVC control 3 (unit 1) : -32 (exp. 1). uvcvideo: device USB2.0 Camera requested null bandwidth, defaulting to lowest. uvcvideo: device USB2.0 Camera requested null bandwidth, defaulting to lowest. uvcvideo: Failed to query (129) UVC control 6 (unit 5) : -110 (exp. 2). uvcvideo: Failed to query (129) UVC control 3 (unit 1) : -110 (exp. 1). uvcvideo: Failed to query (129) UVC control 3 (unit 1) : -32 (exp. 1). uvcvideo: Failed to query (129) UVC control 3 (unit 1) : -32 (exp. 1). uvcvideo: device USB2.0 Camera requested null bandwidth, defaulting to lowest. Any idea how to get this cam working? _______________________________________________ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
