PortAudio will only enumerate devices for the native host APIs that have been configured/compiled in at compile time. You have a 64-bit build of Python/PyAudio and your ASIO device drivers are 32-bit, or vis-versa (64-bit ASIO drivers and 32-bit Python).
PortAudio: portaudio.h File Reference
http://files.portaudio.com/docs/v19-doxydocs/portaudio_8h.html
Depending on the underlying Host API, it may be possible to open multiple streams using the same device, however this behavior is implementation defined. Portable applications should assume that a PaDevice may be simultaneously used by at most one PaStream. Pointers to PaStream objects are passed between PortAudio functions that operate on streams.
