People are keen to tweak everything PC-related, but mice strangely enough are not really subject to comparable modifications.
After reading more into various engineering papers and data sheets dealing with optical input devices, I'm left wondering why apparently nobody has even attempted to mess around with their hardware/firmware. Just looking at this basic instruction sheet (http://www.pixart.com.tw/upload/ADNS-3090%20D...144306.pdf) it would seem easy to, once you gain access, control various aspects of a mouse with basic recalibration of the sensor following the manufacturer's instructions. Access can be gained by directly connecting to the PCB, but manufacturers ship out firmware over USB as well. Forcing/locking higher framerates, controlling voltage and current, overclocking the microprocessor, overdriving the LED? I'm not saying any of this stuff would necessarily yield performance increases, but it's just baffling that nobody has at least attempted to try and see what changing some of this stuff does to the device.
Or have you? I'd be interested in finding out about anything related you have attempted yourself, read about or any insight beyond that you could give as to how gaining access and in practice re-calibrating a sensor could work. I mean, mice manufacturers must do this stuff themselves as well, or they get the hardware pre-calibrated and just specify their needs to the sensor manufacturer. In any case, post-production modifications should be possible.
