i want to control motors according to movement of mouse. Can i do it with ARDUINO UNO by connecting 'Data+' and 'Data-' pins to IC? how can i do it?
Or which ARDUINO i should prefer?
No. Absolutely not.
A USB mouse needs to connect to a USB host. It may work with a USB Host shield but only if the Host shield "knows" how a mouse works. You need to check that out somewhere.
A potentiometer or a cheap joystick can connect directly to an Arduino without any expensive shield.
