title: Keyboard and Bluetooth killed when establishing FTDI USB Serial connection
body: <p>Okay, when I establish a connection using LabVIEW or Python to my Arduino Duemilanove (ATMega328) either my Bluetooth or keyboard is killed.  </p>
  
  <p>I am simply trying to establish a connection to <code>/dev/cu.usbserial-A9007UZh</code> (or <code>tty.usbserial-A9007UZh</code>, but that seems to kill the keyboard or bluetooth even after Terminal is shut down when using python). </p>
  
  <p>I am on a MacbookPro, and I have found that the keyboard is on the same USB hub that one of the two USB slots is on, and the bluetooth is on the same USB hub that the other of the two USB slots is on, which explains the association between those two devices - but what is causing the loss of the other devices? </p>
  
  <p>when I use Arduino (programming IDE) or Cornflake to open a serial connection there are no errors -- and everything works as expected. This just seems to happen with LabVIEW and Python.  </p>
  
  <p>I am on Snow Leopard 10.6.2 and have the latest FTDI USB drivers and am running in 32-bit mode.</p>
