Hi, I tried to the unity wrapper from the sdk but when I launched it, I have an error and don't see any screen from the camera.
To install it I follow the documentation on https://github.com/IntelRealSense/librealsense/tree/master/wrappers/unity librealsense/wrappers/unity at master · IntelRealSense/librealsense · GitHub
In the console my error is :
Exception: Failed to resolve request. No device found that satisfies all requirements
rs2_config_resolve(config:00000000174248C0, pipe:0000000017424700)
Intel.RealSense.Helpers+ErrorMarshaler.MarshalNativeToManaged (IntPtr pNativeData)
Intel.RealSense.Config.Resolve (Intel.RealSense.Pipeline pipe)
RealSenseDevice.Awake () (at Assets/RealSenseSDK2.0/Scripts/RealSenseDevice.cs:87)
A the beginning I thinked it was a problem between my computer and the camera but when I launch Intel RealSense Viewer I found my D415 as Intel RealSense USB2 and I only have Stereo Module avaible and no RGB Module. So what is the problem and how to solve it ?
Thank you for your help.

Your camera is apparently being treated as though it is plugged into a USB 2.0 port, even if it is in a USB 3.0 port. This is a known issue with SDK 2.0. You may be able to get the camera to be properly recognized if you unplug it from the USB port, wait a couple of seconds and then quickly and firmly push it back in.

Thank you for answering so fast.
I tried to unplug and plug with a waiting time between 10 seconds and 2 minutes and no change.
And I tried this solution too without success:

Yes the name is still Intel RealSense USB2.
And in peripherals and printers in Configuration Panel the state of the Intel RealSense 415 is "The device can run faster when connected to a USB 3.0 port"
Ps : This is in French Sorry

The USB2 issue is known to Intel and it is on their to-do list to be fixed in a future firmware driver update.
"D400 Series cameras intermittently enumerated as USB2 device on unplug / plug (DSO-6804)"
Apologies for asking, but are you sure that the camera is plugged into a USB 3.0 port? You can tell which one is USB 3.0 by looking in the port and seeing if the connector is blue instead of white.

I understand why you ask this, the 3.0 USB port is important for good working of Intel RealSense.
I plug it into a USB 3.0, I am sure of this because the connector is blue like you said and, just before it is writting USB3.0.

My own laptop sometimes encounters the USB2 problem. If a quick plug-unplug does not fix it, another method I use is to plug in a chargeable device such as a tablet into a USB 2.0 port when the device is switched off. Once the device begins charging, it tells the computer's USB system to send more power to the ports to provide power for the charging. Do you have a tablet or smartphone to plug in to see if this method works for you?

Do I have to plug my phone when the camera is plugged or I unplug the camera before connect my phone to the computer.

The phone should be plugged in first into the USB 2.0 port, and then the camera plugged into the USB 3.0 port.

No change.
I thinked about something, the cable is important?
Because my Boss forgot the standard cable so I use a USB C Dash.
Do you think this is that's what's blocking me?

The choice of cable can have an affect on performance and reliability. The cable supplied with the camera is the one validated by Intel to work best with it. Whilst other cables can be used, the results will be unpredictable. For example, if a cable is longer than 2 m in length then the camera will tend not to work unless the cable is an expensive high-grade one.
