Zoom H4 and Cubase LE4

I’ve just reinstalled LE4 on a new PC. All working OK for existing audio files on PC, but am presented with a message that the Soundcard Driver will not support direct sound input - by which I understand using my Zoom H4 as an interface for recording guitar etc will not work.

The H4 is not being registered when I open the Cubase ‘devices set up’ but the Asio driver is showing.

What am I doing wrong?

Any advice gratefully received.
