    R200 camera randomly crashes on Dev Kit and Ubuntu

    SJohnson2718

      I have Ubuntu 14.04 and the librealsense drivers running on the Intel UP devkit.  As a test I run the librealsense/bin/cpp-capture utility and watch the RGB and Depth channels stream to the screen.  On my dev kit, the cpp-capture utility can only run a minute or two before the camera device crashes.

       

      robot@robot:~/librealsense/bin$ ./cpp-capture

      Capturing DEPTH at 480 x 360, fov = 54.8 x 42.5, distortion = NONE

      Capturing COLOR at 640 x 480, fov = 54.0 x 41.5, distortion = MODIFIED_BROWN_CONRADY

      Capturing INFRARED at 480 x 360, fov = 54.8 x 42.5, distortion = NONE

      Capturing INFRARED2 at 480 x 360, fov = 54.8 x 42.5, distortion = NONE

      terminate called after throwing an instance of 'std::runtime_error'

        what():  VIDIOC_DQBUF error 19, No such device

      Aborted (core dumped)

       

      Sometimes I can't get the device to come back up and sometimes it does.  I have tried four different R200 cameras because I am privileged enough to possess that many and swapping the cameras and the USB3 micro cables does not help.

       

      dmesg shows the error:

      [22624.696374] input: Intel RealSense 3D Camera R200 as /devices/pci0000:00/0000:00:14.0/usb2/2-1/2-1:1.4/input/input82

      [22625.690427] usb 2-1: USB disconnect, device number 45

      [22626.022180] usb 2-1: Device not responding to setup address.

      [22626.225735] usb 2-1: Device not responding to setup address.

      [22626.426963] usb 2-1: device not accepting address 46, error -71

       

      It is acting as if the USB3 cable gets disconnected.  And I have to say that the little surface mount USB3 micro B connector doesn't make a satisfying connection with the USB3 adapter that comes with the kit.  The connector is free to move up or down a little.

       

      Perhaps I have a poorly soldered USB3 connector on the board.  Any ideas?

       

      Please help,
