MIDI Device Manager problem (not exclusively Cubase Pro 9)

I have 2 M-Audio Midisport 2x2 Anniversary Edition. I am running them with no drivers in Windows 10.1 64 bit. I can’t get driver 6.1.3 to install because of a runtime issue. Cubase’s MIDI Device Manager will only let me use one of the 2 Midisports ports. If I select the other one it does not remember it. Any help would be appreciated here.

You must run the driver in XP compatibility mode if I recall correctly.

Cheers

It was Win 7 compatibility mode however thanks for leading me onto the right road - you’re a legend!
