Usermode-SDK demo not working on Ubuntu System

[dParadiz]

While I can manually write to device framebuffer and touch functionality is working and moving mouse around, demo code fails when initializing device. When I run demo with strace I see that device is busy/ unreachable.

Is it possible that system is locking device because it is treated as touch device and if how do I prevent this? Also I have more the one framebuffere initialized in my system, is it possible that wrong device is initialized with SDK?

I would also appreciate any pointers where I should look next.
