After updating my Mac OS, AudioBox 22VSL doesn't show up in Audio devices nor Audio MIDI Setup in the Utilities folder any more.
But in Universal control, the AudioBox 22VSL interface shows that it's connected to USB.
I've already uninstalled all the old driver and installed the newest Universal Control 2.5.1 many times, it doesn't work.
Moreover, I couldn't update the firmware neither through USB 3.0 ?
