Let me look into delaying the quirk until the driver loads, because ideally the right interface for this is "blacklist xhci_hcd" in /etc/modprobe.conf. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
