adb -d forward tcp:5601 tcp:5601 fails to bundle AVDs of a phone and a wearable

Issue

I try to connect two AVDs. One ist a L-Preview Phone device and one is a wearable device. I get twice the log message that no device was found.

➜  platform-tools  ./adb devices                     
List of devices attached 
emulator-5556   device
emulator-5554   device

If I check it with adb devices, two devices show up.

➜  platform-tools  ./adb -d forward tcp:5601 tcp:5601 # 5556 and 5554 won't work either.
error: device not found
error: device not found

Host OS: OSX Yosemite.

I search stackoverflow for the same question and I tried a lot of stuff but without understanding what's the problem, I cannot learn from my mistakes

Solution

Flag -d is for USB-connected devices. Maybe you should try -e or better specify full device name. Start adb -help for more info.
