Lunev\" via" The NPCM730 and NPCM750 chips have a single USB host port shared between a USB 2.0 EHCI host controller and a USB 1.1 OHCI host controller. This adds support for both of them. Testing notes: * With -device usb-kbd, qemu will automatically insert a full-speed hub, and the keyboard becomes controlled by the OHCI controller. * With -device usb-kbd,bus=usb-bus.0,port=1, the keyboard is directly attached to the port without any hubs, and the device becomes controlled by the EHCI controller since it's high speed capable. * With -device usb-kbd,bus=usb-bus.0,port=1,usb_version=1, the keyboard is directly attached to the port, but it only advertises itself as full-speed capable, so it becomes controlled by the OHCI controller. In all cases, the keyboard device enumerates correctly.
