USB Audio Codec (1) not available

Dear Community. I have an Allen&Heath ZED10 Mixer with the above mentioned Soundcard. I would like to record on my 2008 Mac Book Pro (2008) with Cubase LE4 (Old stuff i know… :unamused: ). At the VST Connections menu (Inputs) the Audio Interface is shown as not connected. By clicking on it a pull down menu appears, where the USB Audio Codec (1) is shown. However, i cannot select it. Therefore i cant record. Therefore i need your help…?

Thank you

ok nevermind. it worked with USB Audio Codec (2)
