installing multiple devices with one driver

my UMDF driver emulates a com port and works fine now. It is possible to have
more than one device controlled by the driver, but when I install this, every
time i install the driver again, it first reinstals the existing instances.
Since the driver is not signed, this means that I have to confirm once for
one device, 3 times for 2 devices, 6 times for 3 devices and so on. How can I
avoid this?

Thanks,
Jan

For testing, test sign the driver. Real easy with the WDK now.
