On a 2017 Touchbar MBP, when connecting a BeoPlay A1 via USB-C/C you get multiple 'connect this device to where' prompts with a Win10 guest. Two symptoms:
1) If VM running, the window flashes rapidly, too fast to click - have to unplug the device
2) If VM resumes from suspend after it's already plugged in, the prompt continuously appears even after clicking 'mac'
In neither case have I checked 'remember'.
