R200 camera randomly crashes on Dev Kit and Ubuntu

[SJohn11]

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

[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,

Scott

I plugged the R200 into a powered USB3 hub and the camera is running now on the Intel dev kit without a problem for 30 minutes. Without the powered USB hub it would only run for a minute or so.

I should have thought of this before but I assumed that the devkit that came with the camera would power the camera. Not so.

Hello SJohnson2718,

It looked like you were missing power for the camera, and you were able to track that down, thank you for sharing you findings.

If you need further assistance let us know.

Regards,

Amy.

are you using the full kit or just the standalone UPboard? if you are using the kit please make sure you are using the attached micro to micro USB3 cable and the attached power adopter.

thanks,

I am using the full dev kit with the power adapter that came with the devkit. Is the "USB 3.0 Type B Male to Micro USB Type B Male Cable" that came with the devkit special? I assumed it was the same as the cables that come with the cameras. I have so many of those cameras and cables floating around.

Oh no. This is my mistake. I used the wrong cable. Thanks for pointing that out. Random crashing was a harsh way to learn. I marked your answer as correct.
