This question already has an answer here:

For example, if you're at your BIOS screen or a DOS environment, when you plug in a new USB keyboard, it appears to be usable almost instantly. But, if you are in Windows and plug in a new keyboard, it has to install drivers or updates, making it unusable for the duration. I realize that you don't get full features of certain keyboards in DOS, so Windows has to install drivers for added functionality. But why doesn't the keyboard start working with basic functionality instantly and continue to install the rest of the drivers if needed, obviously the technology is there to make this happen.

This is more for curiosity than to solve a problem, but any insight is appreciated!

That's what I was looking for, didn't find that when I searched, appreciate it! – Callen L Sep 19 '13 at 14:09
Note: Legacy PS/2 and AT style keyboards need drivers in Windows too. – Ƭᴇcʜιᴇ007 Sep 19 '13 at 14:38

In my opinion, that is just the "style" how windows works. In BIOS there are the basic-functions available. But as you said, there are special functions who need the drivers.

So I think windows don't "trust" the user to use the keyboard until the driver is installed. It's the same with for example the iphone. I've plugged it in to the PC by the USB-cable. Nothing happened, until the driver was installed. Even it wasn't charged.

But as I said, I think its the style of windows.

This isn't a very helpful it's just your viewpoint on how Windows works but very little of it is actually correct. Furthelre my personal experience there isn't a delay when using an USB keyboard which was plugged in at boot time – Ramhound Sep 19 '13 at 14:16
@Ramhound Sorry, I interpreted "but any insight is appreciated" false. I thought that means something like "any thinking about it" etc. – Christian Woerz Sep 19 '13 at 14:20
