I’m not sure of the official name of the program. It’s the most commonly found USB poll rate program on the net (http://www.ngohq.com/news/15043-how-to-increase-usb-sample-rate-in-windows-vista-7-a.html) The files/folder you download should contain this “HIDUSBFU.INF” I checked the poll rate adjustment also via the mouserate checker program…and it was verified. I tested this on Win7 x32 and Win7 x64. Switching between the default 125hz and 1000hz will definitely be noticed by the input lag aficionados.
Update: After testing various joysticks, it seems “so far” that this particular USB poll rate program only recognizes Playstation 2/3 joysticks and PSX adapters. When utilizing a 360 stick, the program does not seem to recognize the stick under the menu as “HID Compliant Game Controller.” I tested the PS3 MadCatz SFxTF VS stick, 360 TE R1 stick, HRAP2 with ps2/ps3 adapter (Sumitomo brand), PS360 modded sticks.
Geadom: What USB PS2 adapter are you using? From what I recall, there were only 2-3 USB PS2 adapters that had zero input lag (Pelican, Sumitomo, and another brand I can’t recall).
