Ok for the benefit of any others who have a similar problem and I did read an unanswered post on VI control forum where a user said he was seeing blinking and crashing in the generic remote set up.
I was also seeing this.
It was a faulty usb device somewhere in my setup.
I figured this out by going to device manager and it was constantly refreshing.
I suspect it is either my board or a USB 3 hub I have connected as I pulled everything from the hub and the refreshing stopped.
I had a quick poke around in the generic remote setup and it seems totally fine now.
I haven’t got time to investigate exactly what it is but wanted to post that this is solved (as far as Cubase is concerned) before I go to work.
