U22mkII (on Cubase and sound output of a Mac / Monterey) doesn't get connected

U22mkII (on Cubaseand and sound output of a Mac Pro / Monterey) doesn’t get found when I boot my computer .
I have to disconnect and reconnect it to “see” it.
Anyone knowing why or what could I do to solve this ?
I have installed (the right way), the Yamaha 3.11 driver.
