Right now I have two separate computers; both Intel Pentium IV's running Windows XP. Both have two PS2 ports; one designated for a PS2 mouse, and the other for a PS2 keyboard. I also have an IOGear KVM switch that has PS2 ports on it. I connect both computer's mouse and keyboard PS2 ports to the KVM switch, and their VGA video ports as well, plug my PS2 mouse and keyboard into the KVM switch (along with the monitor) and I can switch between the two computers just by hitting the Ctrl key on my keyboard twice.

Now, I was thinking I might buy another computer for Boxing Day, but what I am noticing is that few computers nowadays come with PS2 ports for mouse and keyboard. In fact, I looked at one today that had 4 USB ports at the back and two USB ports in front, but no PS2 ports at all.

Now, if I buy that computer, and also buy a USB mouse and USB keyboard, does it matter which USB ports I plug my mouse and keyboard into? Or does it not matter because Plug 'N Play automatically determines what's plugged into each USB port every time I boot up that computer?

Now, I understand that both PS2 and USB are serial ports. I was wondering whether I could continue to use the same mouse and keyboard if I bought two female PS2 to male USB adapters, like this one:

to just plug my PS2 mouse and PS2 keyboard into any of the USB ports on the new computer.

Also, I'm being told by tech support at IOGear, that I CAN't use PS2 to USB adapters with my PS2 KVM switch. They say it wouldn't work, but didn't provide any reason. They tell me I need to buy a new KVM switch that uses USB ports for both mouse and keyboard instead of PS2 ports. Can anyone see any way I can use a new computer that doesn't have PS2 ports with a KVM switch that only has PS2 and VGA ports?
