Today I made a clean install of my iMac.
Unfortunately I lost half a day by figuring out the already mentioned problem.
When I discovered this topic I tried the USB Overdrive method .. and it works.
However, and this is already mentioned in the other topic too, I can't uninstall the program because the problem will come back.
So now I'll get every day a startup message which asks for payment.
But I think I refuse because I already bought a f****** mouse which should work properly!
I also had to raise the speed but that works fine though.
I'm also on version 10.7.5. and I have an USB Mighty Mouse.
Won't update to Mountain Lion because I use a lot of vst plug-ins with Logic Pro which aren't compatible yet.
The strange thing is, I did a clean install 2.5 months ago and also made an upgrade from 10.7.4. to 10.7.5. but till today I had no mouse issues.
By the way, when I upgraded for the first time to 10.7.5. there were also major issues with plug-in validation (solved).
So my question to Apple is > "why?!" 😠
