Hi,
  I'm not being able to install QNX 6.4.1 on a DELL machine. I saw an old thread saying that I need to turn off the USB 
controller (QNX 6.3.x), but my machine does not have PS2 connectors which means USB is the only way the use keyboard and
 mouse.

  Is there a fix/workaround for this ?

thanks,
  Flávio Duarte
