I am using LabView (7.1) to read a single DIO port of a DIO DaqPad 6507 (USB 2) with a pentium 4 PC. If I put the LabView read icon in a loop I notice that the fastest read rate of a single port is about 5mS. Can this be made faster and  what is the limitation: LabView, USB, or NI Daq driver?

Looking at the read icon, it does not appear to have a iteration input, only Task ID (in/out),Line mask, pattern, error in/out, maybe you have a different read icon?
The DaqPad 6507 does not appear to state whether it is USB 1 or 2, if it is USB 1 then does NI have a USB 2 version? What difference in time will USB1/USB2 make?
