Why takes the USB device detection of Windows so long?

"Windows and pretty much any other OS have completely different structure.It is possible that Unix based OSes(any operating system these days except Windows) can make a safe assumption about the hardware that Windows can't.Leading to Windows ""asking"" that piece of hardware if it's true or not and then proceeding based on the info provided by the device.What I explained up here is called ""handshaking"" but I omitted a lot of actual reasons why is handshaking necessary.

Simple answer:Unix based operating systems have a lot more efficient handshaking routines."

"On my windows system here, I just plugged in a regular £2.99 mouse, it started working instantly. Unplugged my G5, rebooted, and plugged it back in. About half a second (I guess mostly for setpoint to initialise).

At school? Takes 30 seconds on boot before peripherals start functioning, 20 if you plug them in after-the-fact. I think it's configuration error, most likely."
