My CUBASE 12 on my Mac Pro/Monterey doesn’t load my UR22mkII!

My CUBASE 12 on my Mac Pro (Late’13) with Monterey doesn’t load my UR22mkII, requiring to plug it in again after booting the computer so it can “see” it.
That means that UR22mkII is not recognised on booting my Mac.
Is there something I can do ? or do I do something I do wrong.
I have the Yamaha 3.11 driver updated.
Please somebody from Steinberg answer this, suggesting a solution.
(Is it a power matter on USB ? Since I connect it straight to the Mac)
