well good luck getting help from us if you refuse to even answer this:

If somebody konws what needs to be done to make a mouse , that exp will be very helpful. i'm not asking for help to the solution or MCU, stackoverflow is more suitable for that.

I'm confused haven't a number of people used higher than 1000hz polling rate with the sweetlow usb overclocking thing. Is this guy trying to say what he is doing is better or just unaware of that. This whole thread is just ridiculous anyway. If you don't want to share information about what you have done other than nonsense ramblings about how great it is why even make a thread.

I'm too exciting after finishing all the things, I'm wrong, I shouldnt start a thread. But at least,you guys konws the possiblity to have a better sport mouse.

the only ways this is better than using sweetlow's driver + a mouse with firmware that supports 8khz is that no drivers are needed and that presumably it works on win7 as well

1. making a mouse requires far more than just writing firmware and using it on some dev board.
2. running a company requires far more than just being able to make a mouse.

It works in win7, I test it several hours ago. And the way the MCU how to com with sensor is very impotant.If the main loop only polls the sensor in 1ms gap, i.e. sync to 1ms usb polling , it;s pointless to overclock the polling rate faster than 1ms using a custom driver, MCU is just sending 0 to the computer while the sensor is not bing polled.

that's what i meant with "firmware that supports 8khz"

e.g. my modded mice have firmware where the sensor is polled every 125us

you can also poll the sensor several times in a single usb frame, but what matters for latency is a combination of 1) usb frame frequency; 2) time between most recent sensor poll and when the data is actually sent to the PC

you guys sure this isn't just some troll? i'm getting that feeling

If use 1ms USB polling ,polling several times is easy.But when under 125us microframe, there's not much time to spend.

the sensor polling latency could be ommited ,if the polling is hanppend before next USB frame.

the only reason to poll several times per frame is if the mouse has capped motion registers anyway like the 3090
