Here’s the thing. I needed a USB mouse; I only had one with a PS/2 connector (A4tech OP-620D).

Then there’s this friend who uses a USB mouse (China-made, “Sony” brand). Short cord, though. And has lights. I hated both.

And since it didn’t make sense to use one for a computer that has a PS/2 port, I had what I thought was a stroke of genius: rewire the damn thing without my friend knowing. Except maybe the fact that his cord miraculously grew longer.

In five minutes, I was done. I would’ve been done sooner if it didn’t take me two minutes to find the damn cutter. Anyway, the transplant worked like a charm.

Now that I had USB cord, I could then re-engineer my PS/2 mouse as a USB mouse, just as I had turned the USB mouse into a PS/2 one.

Status: failed. As it turns out, most PS/2 mice do not have a dual-mode controller that allows the USB type to function like a PS/2 type via a passive adapter (or a rewiring, as in my case).

I probably should’ve just asked my friend to trade mice with me. If only I had a better excuse to not waste 10 minutes.
