    I've tried with 2.6.37-gentoo-r4 kernel, the same :

    Code:
    # modprobe uvcvideo
    FATAL: Error inserting uvcvideo (/lib/modules/2.6.37-gentoo-r4/kernel/drivers/media/video/uvc/uvcvideo.ko): Unknown symbol in module, or unknown parameter (see dmesg)
    
    uvcvideo: Unknown symbol v4l_compat_translate_ioctl (err 0)
    uvcvideo: Unknown symbol video_devdata (err 0)
    uvcvideo: Unknown symbol v4l_printk_ioctl (err 0)
    uvcvideo: Unknown symbol video_unregister_device (err 0)
    uvcvideo: Unknown symbol video_device_alloc (err 0)
    uvcvideo: Unknown symbol video_register_device (err 0)
    uvcvideo: Unknown symbol video_usercopy (err 0)
    uvcvideo: Unknown symbol video_device_release (err 0)
    Is anyone able to help me, any help is highly appreciated.

    Thanks
