Could you post the USB notification code, or a link where to get it?
Or does it simply use WM_DEVICECHANGE?

TIA, wizzszz

  Subject: [delphi-en] Detect Insertion / removal of CF cards


  I am trying to detect when a cf card (or similar) is inserted into a
  drive, I have got some code that detects the insertion / removal of a
  usb device and from here i can detect whether it is of type volume and
  whether or not a disk is present, however if i attach a usb card
  reader with no card and then insert a card at a later date i can't
  detect this occurring - I am currently monitoring the WM_DEVICECHANGE
  message but do not get a notification when a card is inserted /
  removed, does anyone know what message i need to monitor or how i can
  get notification when the card is inserted / removed

  cheers
