I purchased the UR22 MKII on Friday afternoon. I went back home and installed the latest compatible USB driver for macOS. Plugged the UR22 MKII into the USB C Thunderbolt 3 port via USB A adaptor, and used the device with Reason 10 for the rest of the day. So far so good.
Then yesterday I booted up my system for the first time since then and plugged the UR22 MKII back into the same USB port. The macOS system audio settings immediately recognizes the UR 22 MKII, but it then disconnectes as soon as I opened Reason 10. This problem goes on repeating itself. Open Reason and the UR22 MKII gets cut off. Since then I have updated the UR22 MKII firmware but it hasn’t solved the problem. The weird thing is that it all worked fine together on day one. By the way, the UR22 MKII is powered by the USB port and the white USB light on the device stays on whenever it’s connected to the USB port, i.e. the interface remains powered despite getting cut off by my system. What can I do to solve this problem?
