  • Hi.
    I'm getting the following error with SuSE 9.1 and the usb driver:
    ioctl: VIDIOC_QUERYCAP(driver="";card="";bus_info="";version=0.0.0;capabilities=0x0 []): Unknown error 515
    Can anyone help me?
    Thanks, Steve.

     
    • 515 = ENOIOCTLCMD
      which means that the user programs tried to
      use some feature of the V4L api which is not
      supported by the driver. This is normal and
      it should not be a problem: the program then
      just should avoid using that feature.

      Do you have any other problems except that
      message? No picture either? Are you using
      xawtv? Try using gqcam and check with "dmesg"
      if the driver displayed any error messages
      (you may need to increase debug level with qcset).
