Virus TI 2 Snow + LMMS

Anything that doesn't fit into other topics goes here!
Hello,
Did anybody connected a synth expander like Virus TI 2 Snow to LMMS? I would like to send the MIDI signal from LMMS to suche an expandeur, but to connect the USB cable of my PC to the MIDI plug of teh expander, I don't know how to do.
