Hello,
I'm trying to access the raw data from my R200 RealSense sensor however it doesn't seem to work properly and sometimes opens my webcam in my computer. I used other codes like the person tracking, the raw data sdk sample in the sdk sample viewer or even the camera explorer and those work perfectly. However when I try to access the raw data the simple way it doesn't work. Here is the code I use and it doesn't open anything. Before I got the R200 I had the SR300 and it worked perfectly with the code(It's a Intel basic code sample, it should work), I would be really grateful if someone can help me figure out what's going on.
Also I checked the properties of the project just to check if the props file for dynamic properties is in the file and it is.
Thank you,
Sofia Galan

As a quick fix, you may try disabling your computer/laptop's webcam so the only video stream device available is the R200. I did this on my laptop and it works.
The SDK is super vague about how to force connection to a particular device, I looked around and there are ways to do this but you need to know the camera's "friendly name" or device ID which is obscure and not easily enumerated. I would like to know how to do this as well - both how to find the proper way to force the sense manager to use a particular device name/ID and how to find/set/use the device name/ID in general.

device manager can show you most of the info you are asking for. right click on the device and select properties and then details. you can select various identifiers using the dropdown selector under property. how to set the values would be dependent on the app, most likely hard code it.36

If you want to list available RealSense cameras, then specify which one you want to use if there are multiple, the Raw Streams sample has code you can borrow. I've modified parts of the C# sample in my app for this purpose and it works perfectly. I also added a generic "pick the first RealSense device the SDK can find" method in case the user doesn't want to manually choose.
