title: Uploading program to teensy not working
body: <p>i got a brand new Teensy 3.2 with the blinking LED programm on it. </p>
  
  <p>When I now tried to upload another programm on the teensy, Arduino says:</p>
  
  <p><em>Teensy did not respond to a USB-based request to automatically reboot.
  Please press the PROGRAM MODE BUTTON on your Teensy to upload your sketch.</em></p>
  
  <p>The automatically starting window of Teensy, doesn't give me a chance to (for example) reboot the Teensy as well, so something of the connection seems to be wrong or something, but what...</p>
  
  <p>Even if I mannualy press the pushbutton, it's still not possible to upload something. Any ideas why?</p>
