Why won’t my quattro work on my Powered Hub?
According to Midiman tech support, the Quattro has only been tested and proven on 2 powered hubs on the market.
1) the Griffith UH124 – 4-port hub
and
2) the Doctor Bot 7-port hub
Both of these units are powered. If you have any other hub other than these two, Midiman DOES NOT support them.
