Take a look at the topics on USB2AX with the sync read capability

Things are improving, but still around 150 msec for 18 servos.
Is there anything faster than USB2Dyna?
Thx, Friedrich

What is the latency setting on the port ?

To check if movement hat completed I use (VB 2012)
----------------------------------------------------------
Public Shared Function IsMoving() As Boolean
'Anything moving?
Dim Mov As Boolean = False
For i = 1 To 18
Mov = Mov Or dxl_read_byte(i, 46)
Next
Return Mov
End Function
-----------------------------------------------------------
This works quite well but even if the 18 servos are already in their respective goal positions, this routine takes about 600 msec.
Anyone knows of a better way to do this?
