Hello. Im having the same problem. Using Unreal Engine 4.12.3 If Oculus is conected the package wont launch. Sometimes it does but ussualy just closes at startup. I created a new project from scratch, packaged and is exactly the same problem.
I have the Oculus CV1.
If you guys find a solution to this problem let me know.
I have a Vive coming next week ill try with that connected and let you know if i have the same issue.
