Applies to: X-Station
The X Station uses USB 1.1 - not 2.0. This will not be updated on the X Station since there is no need.
With the latest drivers you can achieve a minimum input latency of 1ms and output of 2ms. For 2 in 2 out audio plus MIDI it is not necessary to use a higher bandwidth interface since there is no extra data that needs to be transmitted. This does not mean the X Station is not compatible with USB 2.0 ports - you can run it from any USB port, 1.1 or 2.0.
