FreeBSD r2d2 10.0-CURRENT FreeBSD 10.0-CURRENT #0: Mon May 13 00:54:58 UTC 2013     root at snap.freebsd.org:/usr/obj/usr/src/sys/GENERIC  amd64
>Description:
This is an Ultrabook (acer s3) with only one USB 3.0 Controller (2-ports)

I first noticed that I could not install 10-current using the memstick images, I got stuck at mount root, after upgrading form 9.1 using base and kernel tarballs I noticed that the system has no longer detecting my memsticks.


When connecting usb devices (memstick,hdd) I get:

xhci_do_comand: Command timeout!
usb_alloc_device: device init 2 failed (USB_ERR_TIMEOUT, ignored)
usbgen0.2: <Unknown> at usbus0 (disconnected)
usb_reattach_port: could not allocate new device


More info about the controller:
xhci0: <Intel Panther Point USB 3.0 controller> mem 0xc0500000-0xc050ffff at device 20.0 on pci0

And has I explained in the mailling list, I already tried:

sysctl hw.xhci.xhci_port_route=-1 (and =1) in /boot/loader.conf 
(and in sysctl.conf but I guess the first one is the proper way

rebooted, and still no luck.


>How-To-Repeat:
1: Download a memstick image and dd to a usb, after boot you get stuck at "mountroot" prompt.

2: If you're able to install 10-0 current any other way, just connect a USB memstick to 3.0 controller, and you'll see the problem (unless if this is related to my controller specifically - Intel Panther Point USB 3.0)
>Fix:
Tried: sysctl hw.xhci.xhci_port_route=-1 -> DID NOT work!
