I have several programs that access a particular printer port using
CreateFile() and have problems when 2 programs open the port at the same
time (sometimes i forget to close one).
CreateFile() does not throw an error when a usb port is currently in use as
it does with COM ports. Is there a way to detect if a usb port is in use?

Thanks
