Sequoia 15.1.1 don’t recognize my USB audio Focusrite (Scarlett i2i, 3d generation)

I recently buy a Focusrite audio device (Scarlett i2i for d generation). Unfortunately, the device is not appropriately recognized by MAC OS Sequoia 15.1.1.

Let me describe more precisely the phenomenon. 1/ The connexion between my computer (a MacBook Pro) and the audio device is ok : indeed, in one hand the lights of the Scarlett device do shine, and in the other hand my computer asks “do you allow the connexion of that external device ?”.

Nevertheless, once the connexion is performed, the device does not appear in the list of possible Outputs or Inputs in the « Sounds » options and it not possible to use the audio device (for instance through Garage Band).

Actually, that problem seems to be well known : there is lot of discussion about that problem in the the Apple Support Community and various advices to solve the problem in the "Support" pages of Focusrite website.

I tried to solve the problem by following the various instructions in the Focusrite Support web pages. But it does not work (even if, strangely, I succeed once to have my device recognized by my computer – all the others attempts did fail).

The last suggestions to try to solve the problem were posted on November 2024. Does someone know whether a solution hab been found ?
