I'm thinking that the problem could be in the underlying PortAudio library. Do you have (or can you write, in C) a simple utility that accesses the PortAudio library and tries to perform this same listing?

Also, googling for 'portaudio asio' reveals this tidbit from the official PortAudio docs:

There are cases where PortAudio is limited by the capabilities of the underlying native audio API... the ASIO SDK only allows one device to be open at a time, so PortAudio/ASIO doesn't currently support opening multiple ASIO devices simultaneously.
