attached is a patch.
i've tested by adding multiple serial (mockup) devices in the registry
and also by naming one of the flash drives i have "UEMISSDA".
the method seems to work as expected - i.e. the list is populated as
long as the criteria is met.
if no devices were found it defaults to "COM1" (was "COM3").
