Unless you've modified the default to "Take No Action", Autoplay
should start automatically. You can check the AutoPlay status on
the drive with Tweak-UI powertoy for XP. The option location is
found under My Computer, AutoPlay. Drives shows which letter
assignments are enabled for AutoPlay and Handlers shows what
type of actions are available.
