So, I got a Logitech G502 Proteus Core for Christmas, and I love it. Works great, feels nice, lots of buttons. But today, it has suddenly stopped working. I was moving the mouse and boom, light turns off, cursor doesn't move, buttons don't work, nothing. I did some Googling, but the directions of, unplug, replug, and uninstall, re-install, have done nothing. Still no response. Neither the computer or the Logitech software recognize it as plugged in. And I know the USB port works; I tried switching keyboard and mouse and the keyboard uses that port just fine.

 

I found some topic that said I needed 5 files in C:/Windows/System 32/drivers, among them mouclass.sys and mouhid.sys, but I can't find the other three (they started with an h) and I can't find the page again, and that page didn't even have directions on what to do if files were missing!

 

Does anyone know how to fix this?

Do you have another computer available to test it with?

Try it on another machine. If that doesn't work, call Logitech up and they'll replace it. They have legendary customer service.

Funnily enough as I was sitting here with it plugged in it flashed on for 5 seconds before turning off again.

 

But no, it does not work in my other machine.

I take it that's a sign to send it back to the seller?
