I am on a Mac, I have the Samsung Gear 2 Tizen Watch, and I am seeing this:
$ sdb devices * sdb (2.2.49) already running, and restarting sdb(2.2.51) again * [fatal][src/listener.c:install_listener():81]server LN(26099) cannot bind * daemon started successfully * List of devices attached $
And then my Watch disappears from the device list in the Connection Explorer of the IDE.
