You need to switch the driver in Cubase to use the same driver as the sound card that the mic shows up under. Then you need to setup your I/O in Cubase to match it and make sure that the mic input is enabled in whatever sound card system that mic uses (probably through the sounds and multimedia section of windows in the control panel). If you are using some sort of pro sound card that the mic does not run through, you could run the line out of your other soundcard into the line in of your pro card.
