arduino - Teensy 3.1 keyboard script execution -

i'm trying program teensy 3.1 keyboard, , i'm using example https://www.pjrc.com/teensy/td_keyboard.html . int count = 0; void setup() { } // no setup needed void loop() { keyboard.print("hello world "); keyboard.println(count); count = count + 1; delay(5000); } i uploaded script teensy , script execution starts immediately. problem after if unplug teensy , plug second time, nothing happening. know doing wrong? you're not doing wrong; expected behavior. the documentation states: you may notice "hello world 0" not appear. pc takes brief time detect presence of new usb device, program begins running immediately. if use keyboard.print() before pc finishes detection process (called "enumeration" in usb lingo), keyboard.print() nothing. the remedy stated is: a delay() can added in setup(), if necessary. suggest put nice long delay in setup() give pc time recognize keyboard.

i developed vsto 4 add-in excel. works perfect, however, have button placed in custom tab of ribbon control disabled. after clicked other ribbon button in custom tab, need enable disabled button. i tried with: btncancelar.visible = true; in click event of button, button not shown. strange thing when debugging, still not appear, if messagebox shown, button visible @ last. i don't understand behaviour. how can enable or disable ribbon button dynamically code? i'm not sure language used in project, guess can tranform own language used. i'll show example here in c#: first need implement called callback function in ribbonxml definition: <button id="buttonsomething" label="content" size="large" getvisible="enablecontrol"/> then next step implement callback function: public bool enablecontrol(iribboncontrol control) { return true; // visible ... false = invisible } vsto trigger getvisible callback...
