That's true, if you plug in a usb flash storage device, windows has the standard class driver locally and installs it without any requirement on internet access. Same with standard keyboards and mice.
But compare to linux. On windows, the first time you plug a particular model of usb device into a particular port, it takes 20 seconds to "install the driver" (and then it's almost instantaneous on future plugs of the same device into the same port). On linux, it's almost instantaneous, the first time and every time. New device, different port, still instantaneous.
It doesn't really make sense why it would take longer the first time, or need to happen again when plugged into a different port. silly windows...
