ur22c USB error

I’ve had a new UR22c on W10 for about three weeks and have had dropouts on playback with VI’s. Also usb light would occasionally blink. Have spent that time trying to sort it with posts and support ticket.
No reply to the ticket but someone from Steinberg advised that it’s due to improper device connection.
Makes sense. I’ve connected the supplied usb 3.0 lead, what more can I do?
I mentioned this is another post but I cleaned the plugs with electrical cleaner and the usb light stays on and now works as it should.
Just one solution that worked here out of many others that people are trying.
