You aren't alone. Mine also randomly isn't recognized at startup, probably 2/3rds of the time. The fix in my case is to unplug and plug it back in (even works that way in the same USB port). But this is 2022 and this is such a basic and archaic issue. I don't want to have to go around to the not-easily-accessible back of my PC to do this every time. Not to mention I had to pay the full $80 for it in my region just last month, so I feel a certain extra sting there. 
 
I've done what I can to fix it--plugged it into every different USB port on my PC and tried to startup like that. No go.
 
You have to think there's a way EVGA can fix it on their side and release that fix in a firmware update. Given how widespread this issue is, it has to be feasible. But whether it will be done is anyone's guess at this point.

If you're on an AMD system you may what to plug it into A usb3 port since there have been known issues with USB2.0 causing devices to disconnect. Or check your motherboard's USB settings as some have reported making adjustments were able to resolve their issues. 

Thank you for the suggestions. Currently I have the mouse hooked up to a USB C hub with USB 3.0 ports. I will go ahead an plug it in to a standalone USB 3.0 port in the computer itself. My system is also AMD so I will look into USB bios settings. Still doesn't explain why over time the connection just degraded when the first few weeks it was flawless.

That sucks. Here’s an update from my original post, I moved it to a standalone USB 3.0 port on the back of my computer. Ever since then I’ve really had no issues. I understand your frustration though. Hopefully you can find a solution.
