Audio interface input port not found

Hi, I’m running cubase LE5 with a tascam us-122 audio interface. I am trying to play my guitar directly through the audio interface, however it is not found in the input port of the vst connections. My only option is my laptop’s microphone. I made sure to make a mono input and to activate mono on the audio interface. Anyone know what the problem might be?

Thanks

-Install the Interface drivers
-Select the Interface drivers in Cubase

Thanks, that would likely have solved the issue, however there is no driver for windows 10…seems like i need a new audio interface. Fuckin hell.
