I'll leave my question + answer here, as my problem was solved. I misunderstood how virtual ports are working, but after I change virtual port from 1 to 2 and then create routing, then it works 
In that case I cal also confirm SQ-64 works with MRCC via USB (for USB compatible devices list)
I tried to connect the Korg SQ-64 sequencer via USB, but unfortunately MRCC does not receive note messages. MRCC detects the SQ-64 (appeared in the name list), after setting the midi output channels (USB on, CH number) and playing something on the SQ keyboard, MRCC shows that it receives some signal (green triangle appears as IN) but does not receive notes and does not forward it to synthesizers. I will add that I connect another device to the same port and everything works.
Does anyone have SQ-64 and could confirm if midi works via USB?
