You should buy a standard mouse, no driver needed. A mouse and its protocol is prety simple, but now we achieved the state where a USB connected mouse reports itself as 5 mouse and 3 keyboard and some other HID capable device, good luck using them on legacy or alternative operating systems. (Hint: won't work).

>Bbbbuut what about my programable buttons, led and whatever?

I don't care about that, i care only about that i should be able to buy standard mouse which is always harder and harder task because you buy every piece of s with rgb leds so they will stop to produce non-manchild computer hardware. I wouldn't care at all if the hw would still provide the basic functionality without any special driver, but nooo, thats too much.

Proposal: send the hw back to their HQ and demand your money back.
