Yes its yellow and disabled.
I found the global file and the variable:
# SmDeviceErrorThreshold=MaxNumberOfUnknownErrors
# default: 5
# SmDeviceErrorThreshold >0 is used by session managers to
# define the upper limit of unknown device errors. The device
# will be disabled when number of unknown device errors reaches
# specified value. All other values will disable functionality.
How do i change it now? Should i remove the "#" and set MaxNumber to 0?
