Grep for "USB_2_0_DEVICE". Marcus - of what I've seen (in the USB tree), the USB_2_0 support is for a CPU specific (4xx) EHCI controller. My question was about a generic EHCI controller driver (like the OHCI one), as we plan to use a PCI based USB host controller. I guess we can operate it in the OHCI mode at boot stage and get a slower boot if generic EHCI support is not planned in the near future.
