There is not such thing as "sufficient frequency" for orthodoxal overclocker
4k/8k version: http://sweetlow.orgfree.com/download/hidusbf3.zip
2. take drivers from hidusbf3.zip and install it (copy to %systemroot%\system32\drivers\ directly or to the folder of hidusbf setup and then install service).
3. reboot after 2!
4. run setup.exe, and try to change rate to 31 or 62. Rate=31 actually equal to 4000 Hz, 62 - 8000 Hz. (Don't forget to restart device.)
P.S. Do not use USB hubs (for first try), it can restrict rate, attach mouse to controller ports directly. I first test my best overclockable mouse (a4tech bw-35) with hub (this hub is USB2.0 hub - but this is not help) - and has 1000 Hz only When attached directly to controller - it can reach 1400 Hz average (unstable)
also that's conclusive proof that my (new) x08, with last 4 digits=4103 (41th month of 2003?), does not run at 6000fps, because if it did it would not be possible to have consistent 125us report intervals
too busy to check forums as regularly pm me if i forget to respond
