Mouse DEATHADDER V2 not detected by Synapse in W11

Did you've tried to clena reinstall Synapse?

• Uninstall Synapse
• Download & run this tool: https://rzr.to/Tf53xj to remove any razer drivers/leftovers
• Then restart your PC
• After reboot install Synapse again (as administrator).

If this will not work - try manually updating drivers - choose C:\\Program Files (x86)\\Razer Path, then you'll have few PIDxxxDRV folders - there are .ini files inside, so if you'll choose properly, on the next screen you'll see that it's dedicated driver for DeathAdder V2

It worked! I followed all the points to the letter and finally the mouse is recognized! A thousand thanks!

I have been running into similar issues - your fix did not work for me. I made sure to uninstall Synapse before running the script, restarted, then reinstalled Synapse. Here is my post I have been commenting around: I am also experiencing this issue. We are not the only ones either. I have had this mouse for a little over two years and this seems to be a new issue. This is a comment I just made on another post very similar to yours: " +1 I am also experiencing this. I updated Razer Synapse 3.0 and now it doesn't detect my Razer Deathadder v2. Windows 10 claims there is a "driver error" just like OP. I have repaired, uninstalled & reinstalled, and modified Razer Synapse 3.0 several times each. I tried removing the device from Windows while the mouse is unplugged and Razer Synapse 3.0 not-installed, followed by reinstalling Razer Synapse 3.0 and finally re-plugging the mouse in and that did not result in a different outcome. Razer Synapse 3.0 behaves as if no Razer devices are plugged into my PC. As a result, the Calibration and Lighting tabs are missing and I am not able to see the controls for the mouse at all. As if this whole thing wasn't weird enough, my mouse now has the most unique lighting behavior I have witnessed on a device like this. The LEDs periodically illuminate, only flickering. When they do illuminate, it does the default Spectrum Cycling. When I first observed this I thought, "Oh, a wire is disconnecting and the lights are slowly going out." Until I realized the mouse is only flickering when my PC outputs audio. The mouse drivers are literally reacting to music and my friends in discord. It is the weirdest thing. "
