In a test setup and I had several lock ups. I looks to me the usb b port is pretty sensitive . I had a multitrack running from windows pc running all day but when I connected a second android tablet everything stopped : no connection on tablets, the pc stopped playing (sound card error) and sq locked up. Sometimes my ar2412 disconnects (red flashing light on all ports although only dlink is in use ) Tomorrow my first gig with the sq5 , no ar2412 needed and I leave the pc at home..
