ADB Debugging on LG Watch R

I got a LG Watch R for a programming project. First, I had a Gear Live that was now replaced. When I follow the guides step by step, I never get the "authorize this computer" like I did with Gear Live. My machine runs on Windows 7. My steps were: 1. Setup LG Watch R with my Note 3 2. Dev Mode enabled, enabled ADB Debugging 3. Plugged the Charging Station in my PC (got detected as "Android Composite ADB Interface" with Samsung as Company 4. Normally the popup should appear on my Smartphone asking me to authorize the machine 5. In the CMD, adb devices does return unauthorized In the device manager, the Watch R is recognized as "Android Composite ADB Interface" from Samsung. I have tried [an answer to "ADB doesn't recognize Samsung Gear Live or LG G watch" on Stack Overflow](https://stackoverflow.com/a/24716409/2821954) , but it doesn't change much as it is already recognized as ADB Composite. I'd be grateful for any tips.
