Deathadder v3 side button 2 not working

Sidebutton 2 stopped working on the mouse. I have tried several software fix attempts such as drive uninstall/reinstall, synapse reset, and synapse reinstall. Nothing has worked. I purchased this May 24, 2024.

Hello there, ​@techVividAuburnCORAL427!

 

Try to reinstall your mouse’s drivers. You can also update its firmware. If that didn’t do the trick, then shoot me a PM along with your device’s serial number so I can validate it and check for other workarounds.
