Answer 1

I'll agree with Henk's comment that it's not clear if you want to detect the lack of input from a user or detect whether those interfaces are present at all. For detecting user idle conditions, this might be of interest . For detecting hardware interface availability, this might help .

Answer 2

I do this on my devices.

Just add a Timer and a short function called Reset() .

const int TIME_LIMIT = 50000; // set to whatever you need
int timeout;
Timer Timer1;

void Form1() {
   Timer1 = new Timer();
   Timer1.Interval = 200; // 200 milliseconds
   Timer1.Tick += new EventHandler(Timer_Tick);
}

void ShowSubPanel() {
  Timer_Reset();
  panelSub1.BringToFront();
}

void Timer_Reset() {
  Timer_Stop();
  Timer_Start();
}

void Timer_Start() {
  timeout = 0;
  Timer1.Start();
}

void Timer_Stop() {
  Timer1.Stop();
}

void Timer_Tick() {
  if (TIME_LIMIT < timeout++) {
    Timer_Stop();
    // Here, call your Main Form
    Main.BringToFront(); // I use Panels instead of forms
  }
}
