USB audio interface Aimpro21 HD USB audio (Model AS372N) on macOs Sierra limited to 48K 16bit (even though it's 192K 24bit capable)

The 5.1 / 7.1 usb audio interface Aimpro21 HD USB audio Model AS372N, (sold under the name: Sewell SoundBox Pro on Amazon), needs to be set on "U1" in order to be recognized by macOS Sierra. If set on "U2" it does not work at all. (NOTE that it does not need a driver, so it's not a driver issue.)

With Sierra, "U1" mode - Limited to 48K 16bit...

With Sierra, "U2" mode - NOTHING THERE!? The device is not recognized!

The thing is "U1" limits the device to 48K 16bit audio, the superior "U2" mode goes all the way up to 192K 24bit.

With Yosemite and El Capitan, "U2" mode - Superior 192K 24bit available! Yes!

Why is the best mode not recognize under macOS Sierra? It is available and working great under Yosemite and El Capitan. Again, it does not need a driver: as soon as it is plugged to the computer running 10.10 or 10.11, the device shows instantly in the Audio MIDI Setup and Sound Preferences. Not so with 10.12...

Please Apple, fix this asap! A large number of sound pros rely on usb interfaces, we need the best sample and bit rate available. Sierra has been out for a while already v. 10.12.2.

Let me know if you experiencing a problem with your audio interface under Sierra, USB or other protocols (Thunderbolt, Firewire), and please send feedback to Apple: http://www.apple.com/feedback/macosx.html


UPDATE:
It now works with High Sierra! As noted previously by Fabien in the comments, works with 10.13.2 for him. I'm on 10.13.4, still working. Good news.
