I couldn't figure out where the settings I change with the "Mouse" system preferences are stored. Neither plist ~/Library/Preferences/com.apple..plist nor /Library/Preferences/com.apple..plist changes significantly if I change the mouse pointer speed.
My problem: at work I plug in a usb mouse, at home I use my bluetooth mouse.
When I switch I always have to change the speed because for usb the slider must be at the very left, for bluetooth mouse far at the right. So I wanted to write a script that changes and was hoping to be able to use
defaults write ...

The tracking speed is stored in ~/Library/Preferences/.GlobalPreferences.plist.
The slowest speed shown in System Preferences is 0.0 and the highest is 3.0
You can change the speed by editing the plist directly or with defaults, but you have to log out and back in.
This would change the speed immediately:
