title: Raspberry pi freezed on wifi adapter
body: <p>I have a type B Raspberry Pi running perfectly with USB keyboard and USB mouse both plugged in.</p>
  
  <p>However pi freeze in all the following combinations,</p>
  
  <ol>
  <li>USB keyboard + <a href="http://www.buffalo-technology.com/en/products/network-devices/routers/airstationtm/airstation-trade-n-technology-150mbps-usb-2-0-client/" rel="nofollow">USB wifi adapter</a> (CUI)    </li>
  <li>USB mouse + <a href="http://www.buffalo-technology.com/en/products/network-devices/routers/airstationtm/airstation-trade-n-technology-150mbps-usb-2-0-client/" rel="nofollow">USB wifi adapter</a> (GUI)</li>
  </ol>
  
  <p>In CUI, pi reboots every time I hot plugged in the adapter, and freezes on asking for login id.
  If I boot pi with wifi preplugged in, pi also freeze on asking for login id.</p>
  
  <p>In GUI, it does not reboot but freeze when I hot plugged in the adapter.
  It is true when I boot pi with preplugged in. </p>
  
  <p>Could someone please advise me how to fix this? </p>
