I really would like to have an audio interface with a USB hub, however it is the only good thing about the M-Audio Air Hub.
The level of the sound that interface outputs is extremely low - ona my Adam T7V speakers the XLR input is supposed to be more powerful. Nothing like that with the M-Audio AIR Hub - the device is extremely quite.
Also on Windows 10, the system is constantly loosing the device , meaning that you should go to the Sound Settings each time and set again the audio interface. I read on other websites that other people have experienced the same issue. Most probably the drivers are not that good.
When I purchased it it looked the device I need, however it turns out to be a total disappointment.
