I do not see any solution to take the control of my trackball at my

Should I write a kernel extension ?
Any advice would be greatly appreciated.
You should be able to do this in the user space thru IOKit. Write a
matching-dictionary with the specific values (eg idVendor and idProduct)
for your device and the control it however you need to.
If you have the Dev Tools installed you should be able to get more info

Hope this helps,
