[lcd4linux] unpluging the usb device-bug?

[tasos <ta...@ya...>]

hello again.my situation.starting lcd4linux.unpluging
the  usb device and it keeps running.
So:

  signal(SIGHUP, handler);
    signal(SIGINT, handler);
    signal(SIGQUIT, handler);
    signal(SIGTERM, handler);

if (timer_process(&delay) < 0)
Those are the cases where it gets our of main loop.
I just want it to be killed(stopped) when the device
is unplugged.
Any ideas PLEASE?
