M-Audio Oxygen 61 controller

I am using Cubase Elements 9 and I recently purchased an M-Audio Oxygen 61 Mk IV controller. What I am finding is that Cubase does not always pick up the controller (despite the controller being plugged in and power on prior to starting the computer and the controller appearing in Windows 10 device manager). I usually have to restart Cubase several times before the controller works and more often than not restart the computer. Is there anything I can do to get round this? I had an Alesis Q49 and it worked well. Any advice would be gratefully received.
