1) do you have an Application Note for iow56 connecting to 32/64 LEDs?
or does the same app note as iow24 applies? I am interested in the led power driver chips etc,
whether we can use the same ones.

2) While the reporting rate of the iow56 is 1ms, Windows XP have a ...

I understand the IOW56 has a 1ms latency period as opposed to the much slower IOW24 and am interested

Are the software side of things very similar? I.e., will a great deal of ...
