SWT: Getting notified of a system device change (USB device connection / disconnection)

Question

I'm writing an SWT application which needs to sit in the system tray and pop up automatically whenever the user connects some USB device (the application serves as its control panel).

The way to do this in the native environment (win32 in this case, but I should be platform-independent ultimately) is to listen to the WM_DEVICECHANGE event, then checking if my device has been disconnected.

Googling the subject, it seems like SWT does not in fact handle this type of event. Does anyone have any idea as to how to achieve this? My fallback solution would be sampling the USB port every n seconds, looking for the device, but this is a no-no solution as far as I'm concerned...

Thanks and cheers

EDIT: J-16 SDiZ reported that the API exists for Windows too

Here is a very good article about Access USB devices from Java applications

The described jUSB module contains a USBListener object.

Interface implemented by objects that want to monitor USB structure. The order in which these changes are reported is not necessarily going to be the order in which the changes were seen in the real world, and delays also occur.

Youre SWt object can implement this listener and do something, when the method

deviceAdded(Device dev) 

is fired
