The best fix is to get Vista to run at at least 500Hz poll rate.

This is easy to do with full-speed USB which does not have any constraints on poll rate in Windows. Also 16 bit data packets.

Well, I'm using an Opti-PAC.   ;D

On XP, it was limited to 125Hz until I ran the USB poll rate patcher hack.  Then I could use up to 1000Hz without a problem.

Are you saying you know of a way to get the Opti-PAC do more then 125Hz on Vista 64?
RandyT:
This difficulty, which is not insurmountable from what I have been reading on the web, appears to be primarily an x64 thing.  Other Vista and XP varieties are much easier to tweak the polling rate with.

Not on the device side, no, but our trackball and spinner interfaces, and U-HID boards use full-speed USB with a poll rate of 2 Ms with 16 bit packets.

With the simple patch (most Windows OS'es) and no different hardware, a 1 ms poll interval is possible, which is twice as fast.  Although anything over 300hz is probably overkill anyway, especially for low resolution trackballs.

Hey RandyT,

if it's possible to do it on the hardware side, why not just do it so that the user doesn't have to mess with the patch and it won't matter what OS you have it would be Plug n play?
