    Subjectusb ov511 problem (kernel crash)


    I have an HP Omnibook 6000 laptop. When I plug in the D-LINK DRU-100C
    (Ver. B2) usb-camera, and load the ov511 driver, the camera is detected
    just fine. But, when I try to use the /dev/video0, the whole kernel
    crashes! The same happens when I do "cat /dev/video0". There's nothing in
    the syslog. Sysrq wont work.

    I'm using Linux 2.4.10 and driver that comes with the kernel. I've also
    tried the 1.42 ov511 driver from I use Debian GNU/Linux

    Any ideas?
