USB MIDI device not seen by Cubase [SOLVED]

I cannot get my PC Cubase to see my Korg Krome, connect by USB. I have installed the Korg MIDI-USB driver, and when I run the Korg supplied application it can see the Korg listed in the MIDI devices fine. If I unplug the USB cable it disappears, plug it back in and it appears.

SOLVED - It was this :

I have other USB-MIDI devices connected to Cubase and it sees them all fine.

It is not appearing when selecting a MIDI out from a MIDI track, and it is not in the “Device Setup - Midi Ports” section of Cubase.

I have had the device working on a different PC previously, and I am 99% sure I am using the same software driver download I used last time. I have tried uninstall/reinstall, rebooting, and making sure I have the Keyboard up and running properly before loading Cubase.

Any ideas - something simple/silly I’m not doing properly?

Windows 7 64 bit, Cubase 8.0.2
