WinCE6.0 - Notifications for "Unknown" usb devices

Hi,
Is there a way to get device notifications (WM_DEVICECHANGE or any other
equivalent, if any!) for "unknown" usb devices? Here unknown devices means
usb devices for which drivers are not installed.

I tried this - After inserting a usb device for which drivers are not
present, I did an enum of all devices (wilcard as *) using
FindFirstDevice/FindNextDevice. Even this loop did not list the "unknown"
device!!

The basic intention is to call "lpDisableDevice" exposed by USBD in order to
re-enumerate the device.

Any comments are welcome

Thanks,
Sri
