[SOLVED] Mouse pointer and the DPI button don't work

[Geyser47]

I use a Dragonwar ELE-G9. Its been a little more than a year since I bought this mouse from amazon. Its been working perfectly since then until recently when the DPI button stopped working. Since then I cannot change the DPI either with the mouse or from the configuration settings. This happened a couple of weeks ago. Also, the mouse pointer is a quite a bit laggy. It doesnt work smoothly at all.

I've already checked the USB cable as well as the LED light at the bottom. Both work perfectly fine. Please help me on what to do! Thank you.

Check the mouse in another USB port
Check it in another system

Is the driver and firmware up to date?

And try a different, known working mouse in the current system.

Per @helpstar's suggestions you must continue narrowing down the possible source of the problem.

Determine if the problem follows the Dragonwar mouse or stays with the current system.
