ADB Debugging on LG Watch R today 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 the gear live. My machine runs windows 7.
My steps were:


Setup LG R with my Note 3
Dev Mode enabled, enabled ADB Debugging
Plugged the Charging Station in my PC (got detected as "Android Composite ADB Interface" with Samsung as Company
Normally the popup should appear on my Smartphone asking me to authorize the machine
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 the following: https://stackoverflow.com/questions/24583354/adb-doesnt-recognize-samsung-gear-live-or-lg-g-watch/24716409#24716409 but it doesn't change much as it is already recognized as ADB Composite.

I'd be grateful for any tips.
I ran into the same problem. It turns out that the watch has to be connected to an Android phone running the Android Wear app; then the "authorize" dialog will appear on the Android phone. After you authorize you can unpair the phone.
