Additionally, host controller drivers are loaded by the PCI subsystem when a corresponding host controller is discovered during PCI enumeration. The host controller driver is thus also responsible for initializing the host controller and perhaps loading the USB Hub Driver and the USB driver. Combined, the USB driver, USB hub driver, and the host controller driver make up a USB subsystem. |
