Hi, The FreeBSD XHCI driver does not use the speed information provided by the XHCI PCI descriptors currently nor any internal registers. Even if the device is 10Gbps capable it will be listed as 5Gbps. If you have an XHCI 1.1 device and the FreeBSD XHCI driver works, we might want to update the manual page. --HPS
