All buttons work, the logo lights up, the cursor does not move. I checked it on different computers, it worked for several months until yesterday. What could be wrong? Windows reinstalled, mac os reset. It doesn't help, apparently the problem is in the mouse! Does not work on any computer. I can't get support, because I didn't buy it in the official store! The mouse was rarely used. For all the time, maybe 100 hours worked. I left it connected for a day after playing cs psch, after which, in the morning, it no longer worked. I tried everything I found on the Internet, it didn't help!
