I looked at this year's ago with led mice. Allot of mice use chip sets that you can't find any spec's on. Some logitech mice use Avago chip sets that have published interface data sheets. With out a USB port on the RC the interface is a problem. The communication protocol with the chip set is SPI. The faster mouse engines must have the code loaded into the mouse chip. It's complicated but do able. This is probably a case where a coprocessor would be good. The coprocessor could interface with the serial port or the SPI port and just send the cleaned up x and y data. In the end the problem is optical. The vertical height must stay with in a very close tolerance. Modifying the optics can be very difficult. It can be done but this is going to take allot of work. I got it working on a vex bot. How ever the chip set is now obsolete. Optically the laser mice are much more tolerant. A USB HID to serial converter might be a way to go.
