Basilisk v3 not detected by synapse, when plugged into pc it flashes red

My basilisk v3 wired mouse is not recognized by synapse and won’t fully connect. It flashes red when plugged into my desktop and the cursor starts to glitch. I’ve had this mouse for around 4 years and never had this problem before. I am also on razer synapse 4 and have repaired all the apps countless times.
I’ve uninstalled Valorant and its anti-cheat. I’m not sure if it is fully uninstalled.

I also can’t run the firmware update for my basilisk model.

 

Is someone able to help fix this problem?

Hello there, ​@Jalen2008!

 

Are you using a USB hub? Try plugging it directly into your PC’s motherboard. You can then use the Device Detection Troubleshoot Tool. If that didn’t do the trick, then shoot me a PM along with your mouse’s serial number so I can validate it and check for other workarounds.
