What makes a webcam/keyboard/mouse special for PS2?

I mean, there are certain games that support keyboard/mouse but not all of them work properly, some even dont work or calibration is all over the place.

Pretty much the same with Police 24/7 Konami's Capture Eye web camera. It doesnt seem to work with my cameras (both Eyetoy models and a bunch of other old logitech cameras).

What kind of input/imagen support has Playstation 2 to not work with every single input/image device? Can this be hacked? Has anybody in PCSX2 Team debugged those games with specific peripherals?

My guess is resolution or image format. I am kinda surprised so many are compatible. If you want to look in to what all these web cams have in common odds are you would find out why they work and the eyetoy and modern web cams do not work. Honestly I don't think even non Justifiers even work with this game.

All those cameras? Really? Wow, not even one Logitech camera when it is, by far, the most famous webcam brand of all times.

I will try to buy one of those.
