There are a couple of issues left, but right now the code is in a state were enumeration of USB devices is possible and there are no dirty hacks :-) The XHCI chip, which is the PCI interface for USB 3.0, is a replacement for OHCI/UHCI/EHCI and can also drive USB Super Speed (4.8 Gbps). I expect there to be a througput and performance increase when switching over to the XHCI interface also for 2.0 compatible devices, because it has a better data queuing mechanism. Currently all code has been committed to the USB P4 project at FreeBSD.org. You need to copy all files under sys/dev/usb + sys/modules/usb/xhci into 8- stable for example, and then build a new kernel. You need to manually to cd into sys/modules/usb/xhci and type make all install after you built the kernel.
