Platform independent patch.
Tested on: i386, motherboard ASUS P4P8X, mice Logitech MX300 and Logitech G5, game ezQuake 1.9.
>Description:
Add "options UMS_HZ=<INT_VALUE>" in kernel config.
USB mouse rate: value from 1 to 1000, other values set default rate - mouse specific.
Most mice suport till 250Hz and 500Hz. Greater value - smoother movements.
Some of "professional gaming" mice support 1000Hz and have default rate 500Hz.
User can to change this value using sysctl hw.usb.ums.hz.
For applying it user must take out mouse and insert it back.
>How-To-Repeat:
Use usb mouse. :-D
