title: How to disable "USB Over Current Notification" popups in the Finder in Mac OS X 10.6?
body: <p>On an Intel iMac (Model MB324LL/A) (currently running 10.6.4), every few minutes (or seconds) I get a Finder popup window reading: </p>
  
  <blockquote>
    <p>Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.</p>
  </blockquote>
  
  <p>In Console, the associated message:</p>
  
  <blockquote>
    <p>USB Notificaton: The device "EHCI Root Hub Simulation" @ 0xfa000000 has caused an overcurrent condition. The hub it is attached to has been disabled.</p>
  </blockquote>
  
  <p>What I want: a way to prevent these messages from showing up in the Finder. Any solution that prevents or reduces the annoyance would be most appreciated.</p>
  
  <p><em>For reference: this occurs with our without USB devices plugged in, with any boot disk I've tried. I've reset the SMC and the PRAM. I assume it's the motherboard, and I'm simply looking for the cheapest way to make this a usable paper-writing, web-browsing beast of burden.</em></p>
  
  <p>Thanks!</p>
