I am using a 5V IBM TrackPoint module as a HID mouse. I am connecting the TrackPoint's PS/2 RESET, DATA, and CLK to digital pins 13, 9, 3 via a Logic Level Converter. All works well. The TrackPoint is powered via the Teensy 3.1's 5V VUSB.
I am using the GND pin next to the RESET button.
I've been told that the Teensy 3.1 digital pins are 5V tolerant, so I removed the Logic Level Converter, and connect directly to the Teensy, but nothing works.
Do I have to set anything to enable 5V tolerance? or am I mistaken in its use?
Can anyone suggest what to try next, please
Here is a link to the setup thread on the thinkpad forum:

And a link to the library on Github:
