Help: mini ps/2 trackball on windows 7

[Sp3c7r3]

Hi, I bought one of those cheap mini illuminated trackballs

My computer doesn't have the green/blue ps/2 ports in the back, no biggie I thought, I have one of those ps/2-to-usb adapters.

When I plug it in, windows doesn't make the usual "sound" for when new hardware is found, but the trackball gets power as it illuminates. I tried various things to make it work. One suggested editing the regedit, that didn't work. Another suggested to enable ps/2 in the bios, but it's not even available in my bios options, probably because the ports are not even on my motherboard. And lastly I tried to download a ps/2 driver, but that didn't work, but maybe I did it wrong?

I read that ps/2 is a dead format and is no longer supported, so is there any way I can get this to work?

I think you need to make sure that the PS2/USB is an 'active' type of an adapter instead of passive.

Yes,
It has to be an active converter .
I bought this:http://www.amazon.com/gp/product/B0007T27HI/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1
To work with that trackball and my computer.
It even works with the raspberry pi.

You have to use the right adapter. The purple ones are for keyboards; the green ones are for mice.
