Hi, It is this one: http://www.intel.com/technology/usb/download/xHCI_Specification_for_USB.pdf I currently have a PCI express card from some vendor, which implements support for the XHCI spec. and I've seen good results so far. I would very much like to test the XHCI driver on ARM, if any chips exist yet which has the XHCI included in the ASIC. --HPS _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
