m5602 - gspca: set alt 0 err -110

  • Anonymous - 2009-07-04


    I have a problem with my ALi m5602 with ov9650 in 2.6.30. The modules load fine, detect the cam and create /dev/video0 device:

    gspca: probing 0402:5602
    ALi m5602: Probing for a po1030 sensor
    ALi m5602: Probing for a mt9m111 sensor
    ALi m5602: Probing for a s5k4aa sensor
    ALi m5602: Probing for an ov9650 sensor
    ALi m5602: Detected an ov9650 sensor
    gspca: probe ok
    usbcore: registered new interface driver ALi m5602
    ALi m5602: registered

    But when I try to use the device (with cheese, xawtv or skype) the application gets errors:

    libv4l2: error dequeuing buf: Chyba vstupu/výstupu # that means (I/O error)

    and in dmesg I see this:
    gspca: set alt 0 err -110

    This cam works just fine with 2.6.28 kernel with the old non-gpcsa m5602 branch.

    Thanks for any suggestions.

      Is this with the stock 2.6.30 driver or did you install the one from the m560x project repository?

        Now that was fast :)

        It's debian source kernel package (pretty much stock as far as i'm concerned).

        Now I've tried with http://linuxtv.org/hg/%7Eeandren/gspca-m5602/archive/tip.tar.gz (which I've got from http://m560x-driver.wiki.sourceforge.net/howto_install ) with the same results.

        Is there some better repository which I should try?

          What machine is this?
          I'm also using debian, 2.6.30 and it works perfectly with my ov9650 camera. Are you sure you haven't enabled some kind of killswitch on the laptop?

      It's an asus amd64 desktop pc and the camera is mounted on asus PW 201 LCD display. No killswitches.

      Can I debug this somehow? On the old driver, there used to be a debug option on the module.

      The error is emitted by the parent module - gspca and thus is out of my knowledge. I would advise you to send a mail to linux-media@vger.kernel.org explaining your issue and then we can try to solve with the help of some smarter guys. As your camera is on an external monitor it's kind of a special device. All other users of this driver are laptops with a builtin cam.
