Hi Damjan,

I figured out this mouse did not work with some other boards too. In
some boards no cursor at all, in others like described above, it went
crazy. I found that this was no software issue, it did not matter what
OS you used, it only mattered what motherboards you used.

When I had thousands of one particular type of Intel G31 chipset boards
in my stock for which this mouse did not work, I had to find exactly
what was it. It was the controller IC that is NOT COMPATIBLE (what's the
reason?) with some boards, both cheap and expensive.

The problem controller IC was: MX84511FP. I replaced this IC with
MX84521FP (without touching anything else), the mouse works like the
best mouse in the world in all boards that I can test.

Thanks

Bal
