I'm sort of a noob in this area but I checked /S/L/E and found a file named GenericUSBXHCI.kext
also, in IORegistryExplorer, I have a PS2K and a PS2M section, both replicating the keyboard/mouse. Is the kext I mentioned in the /S/L/E folder the correct thing to delete or is that the one I need to keep?

My laptop is the 4530s

No, it's kext for USB 3.0.

Do an EC reset may help your touchpad keyboard problem.

What is "KB Mouse"? Is that a specific brand/manufacturer of mouse?

For EC reset, use search.

Are you referring to an internal or external keyboard?

And what brand/model of mouse are you using? Which USB port is it plugged into? Or is it a bluetooth mouse?

Wasn't this a known issue, when sometimes internal keyboard&trackpad would not respond at startup?

It actually happens to me as well sometimes , but in rare occasions. I just reboot and everything works again

OP is talking about a mouse, not trackpad...

Let the OP untangle a bit.
