I think there are some drivers for slave controllers; " USB Devices can also have Linux inside, using a "Device Controller" driver. One example may be familiar: some pocket PCs use SA-11x0 ARM-based CPUs, which integrate a USB device controller. The Linux distribution hosted at handhelds.org includes an SA-11x0 device controller driver which talks to the "usbnet" driver."
