I have done some research and this appears to be more difficult than it should be.

  • PORT_INFO_2 doesn't provide much information (http://msdn2.microsoft.com/en-us/library/ms535509(VS.85).aspx)

  • SetupDiEnumDeviceInterfaces (http://forum.sysinternals.com/forum_posts.asp?TID=4544 and http://msdn2.microsoft.com/en-us/library/ms793116.aspx) doesnt find enough interfaces:
    DevicePath=\?\acpi#pnp0501!#1#{4d36e978-e325-11ce-bfc1-08002be10318}
    DevicePath=\?\acpi#pnp0501!#2#{4d36e978-e325-11ce-bfc1-08002be10318}
    
  • There is an entire library for doing this (http://www.naughter.com/enumser.html) that checks seven different methods for com ports, but its licence may be incompatible with GPL
