Android build hangs when connecting Single3D profiling

My android game freezes when I attack unity profiler. I am using unity version 4.5.3 on OSX 10.9.4 for an instance of my game running on Android N7 running Android 4.2.1. Unity builds the game using Android tools r23.0.2, android SDK 4.4.2. The minimum API level is 17. I don't strip bytecode at all and I am working with full .net 2.0 compatibility. The device is connected to a laptop via USB.

My development builds deploys and works fine and I see N7 in the profilers dropdown. But when I try to connect, the game on the device freezes. There is very little information in the logcat, but it might be related:

W/Sidekick_GmmLocationProviderImpl(9312): Unable to bind to GMM NLP
W/ActivityManager(489): Unable to start service Intent { act=com.google.android.location.internal.GMM_NLP (has extras) } U=0: not found

      

        
        
        
      

    

The unity editor remains responsive, but the profiler does nothing. I tried restarting unity and device but had no difference.

Any ideas?

EDIT: With a device on Wi-Fi, I can see the USB and Wi-Fi connection in the profiler dropdown. Both seem to have the same freeze problem.
