You didn't mention that your keyboard has only one connector that you're using for both USB and PS2.
It always helps to give all relevant details...

I will attach a USB to PS2 adaptor. We don't have any electronic inside the adaptor. It just route the 4 signal pin


But why not have separate connectors?

Is it really cheaper to supply a separate adaptor than to build-in 2 connectors?

It's just another thing for the user to lose...

What does the USB spec say about using the USB socket for non-USB purposes...?
