' Is there a way to force controller _DEVICES to be cleared and re-detected?

' For instance, when _DEVICES is first used in a running program the detected

' number of controllers will be returned. If one or more of the detected

' controllers is then disconnected the _DEVICE$ for the disconnected

' controllers will add "[DISCONNECTED]" to the string returned but still

' occupy a place in _DEVICES. If a user were to start plugging in random

' controllers after program startup the _DEVICES value will just keep

' growing with each new unique controller connected. The program listed

' below will show this in action. I would like to clear the _DEVICES list

' when a controller is listed as "[DISCONNECTED]" so _DEVICES can recount

' the actual number of controllers still plugged in if this is possible

' while a program is running. Any thoughts?
