PS2Communication Library Issues

Troubleshooting
1

Hello,

I’m having trouble getting the PS2Communication library to work with the Photon and the example PS2Mouse code. I’m attaching an image to reference the hardware. The PS2Mouse code runs but I believe no data is being passed back and forth between the devices. The log never shows a data log and simply prints " - not a valid mouse type" continuously.

I confirmed the mouse is jumper wired correctly because if I use the original USB cable and the 4 wires (data, clock, VIN, and ground), the mouse works properly with a computer. So, I believe the problem is between the library and mouse. Any help in troubleshooting the library would be appreciated. I believe the mouse reset should be the first command to succeed. Is there any way to determine if mouse reset is working with a very simple example? Has anyone else had success recently with a USB mouse?

You mean you have got a computer with a PS/2 receptacle and tried it on that?
If so, then I'm surprised my lib does not work, but sure I've only tested against a very limited batch of PS/2 mice.

What is the exact type of mouse you're using?
Not all USB mice nowadays still support legacy PS/2 fallback, so that needs to be confirmed first.
