WinUSB: How to tell if the device has gone

error code is something about a device is not functoning. Is there anyway
to find out that this has happened without doing the control transfer? I'd
like to know so that (a) I can tell the user that the device has gone away,
and (b) perhaps relate its going away to something else happening in the
system at the same time.
From USBTrace I know that nothing goes down the stack to the USB bus.
TIA,
Bill
