After press the button of "start capture" in "cpp-config-ui", no depth image displayed, and it crashed after changing some parameters named with "R200_".

Depth image cannot be displayed in every app.

![Uploading Screenshot from 2016-03-11 12:19:31.png…](This is the image after running)

When I running the "cpp-alignimages", messages constantly showed in the terminal:

Do you have a Windows machine handy to double check that the camera is working? Because the camera has so many additional steps on Ubuntu sometimes it's better to quickly sanity check that it's not the camera hardware (which happens on occasion... could also be USB cable, USB host controller, etc).

SandW commented 8 years ago

I can use the camera under Win10 using intel_rs_dcm_r200_2.1.24.6664 and intel_rs_sdk_runtime_8.0.24.6528. It works pretty well.

ddiakopoulos commented 8 years ago

@SandW maybe try running the ./scripts/patch-uvcvideo-4.4.sh v4.4-wily script again. Looks like that step might have failed without providing an obvious error.

The crashes from cpp-config-ui, while confusing to new users, are usually the result of altering R200_ controls that were only meant to be modified before or after streaming has started. Our example UI isn't smart enough to disable controls according to when they are available to set.

SandW commented 8 years ago

Thanks! I have followed your instructions. However, no image was shown in the cpp-config-ui after click start capture. It exited automatically after a few seconds. Then no device can be found. I plugged in the USB again and no device can be found, unless I reboot my PC.

@SandW this sounds suspiciously like you're on hardware that is incompatible with the camera. I've never seen a case where a reboot is necessary to re-enumerate one of the cameras.

SandW commented 8 years ago

Have you tested in in NUC under Ubuntu 14.04? I can try my NUC.

bobdavies2000 commented 8 years ago

My NUC running Ubuntu 14.04 works fine with the r200 and the f200.

ddiakopoulos commented 8 years ago

@SandW we've found in a couple cases that sometimes these issues can be fixed by twiddling with BIOS settings like "USB Legacy Support" See this issue: #105

SandW commented 8 years ago

Thanks! I will try.
