This issue wasn't solved from me too ...

And ib_ucm was loaded when this device file wasn't created for me ...

I tried to understand why we have this failure (distribution / arch /
kernel / udev version)
And the failuer seems to be random (two machines with the same
attributes: one of them
Have this file and in the other the file wasn't created ...).
