High Sierra 10.13.2 cannot find my audio device

I'm using an external audio interface, "M-Audio Fast Track Pro", which was automatically recognized by the OS until now. After updating High Sierra to 10.13.2, which one of its improvements is about a best "compatibility with certain third-party USB audio devices", my iMac 27" Mid 2011 don't recognize the external audio interface at all!!!!

What the heck is going on? Is it a simple "bug", and I have to wait for a new update in order to use again my audio interface? Or is it simply considered an old device and no longer supported?

Thanks for any answer!

iMac (27-inch Mid 2011), macOS High Sierra 10.13.2

I've found a way to momentarily make possible the FastTrack Pro usage:

I've upgraded the OS just a week ago (it was El Capitan), downloading the High Sierra installer from the App Store, and the version was 10.13.1, then I've updated it to 10.13.2, obviously through the App Store.

Since I still have the macOS installer, I've tried to use it and the result is literally a "downdate" to 10.13.1!

Now M-Audio FastTrack Pro is working properly, but I have unchecked the automatic download and installation of updates in "System Preferences > App Store": I won't never update the OS from now on, until I will sure that this great audio interface is supported!
