Using multiple interfaces with Cubase

I am wondering if there is such a thing as an ASIO drIver that will connect to multiple interfaces at once - I have an ASUS STX Essence card (with ASIO driver) and a Focusrite Scarlett 2i2 USB (with ASIO driver). I can switch between the two, but I only get one at a time - Focusrite doesn’t recognize ASUS, and ASUS doesn’t recognize Focusrite. Ideally, I’d like to be able to select one or the other in the connections setup, so I could take advantage of the outputs on each - perhaps set up two monitor mixes, or use outputs for external effects. Is there some sort of ASIO driver available that will recognize both at once?

Related question - If I got another Focusrite interface and plugged it in, would both interfaces be recognized by the Focusrite ASIO driver?

OR - is my final answer, “just get a new interface with lots of inputs and outputs”?

Thanks in advance!

Asio4all allows using multiple devices, though the latency will increase in comparison to manufacturers asio driver.

The answer to your question about focusrite interfaces - please check that with focusrite. It depends on the driver they provide. Some suppliers allow multiple instances of their interfaces to be controlled by one single driver. I am not sure about Focusrite.
