I have a Technaxx usb 3.0 pci-e card that uses the Nec chipset and it works 
perfectly with the xhci.ko driver here :

kldstat -vvv | grep xhci
                308 xhci/usbus
38    1 0xffffffff82101000 10e28    xhci.ko (/boot/kernel/xhci.ko)
                46 pci/xhci

dmesg -a | grep xhci
xhci0: <XHCI (generic) USB 3.0 controller> mem 0xfbefe000-0xfbefffff irq 19 at 
device 0.0 on pci4
xhci0: [ITHREAD]
usbus1 on xhci0

I'm running :
uname -a
FreeBSD bsdaddict 8.2-RELEASE FreeBSD 8.2-RELEASE #7: Wed Feb 16 13:33:10 PST 
2011     root at
source/8.2/sys/PCBSD  amd64

Hope this helps,
