Error occurred while installing the application: Invalid <device> specified (Flash Builder 4.7)

im just fraking out with this problem. Sometimes I'm getting this stupid error message, when I try to debug my mobile application:

Error occurred while installing the application:

Invalid specified

The app wont be installed on the device.

I've tried:

clean project
restart Flash Builder
restart Mac
restart iPhone
delete app from device
trying a new workspace
/Applications/Adobe\ Flash\ Builder\ 4.7/eclipse/plugins/com.adobe.flash.compiler_4.7.0.349722/AIRSDK/bin/adt -devices -platform ios

Sometimes the message is not shown, but then the app even is not installed on device or I do not get a connection for debugging! (See Screenshot 3) But in 99% I get this error message!

enter image description here

System: Mac Pro (Late 2013) OSX 10.10.3 Flash Builder 4.7 AIR 17 Flex 4.14.1 or Starling 1.6 (the problem exists in all projects)

Solution

After switching off all debug devices the problem do not longer exists.

But this should not the solution for this bug!
