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.

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)
Tried: sysctl hw.xhci.xhci_port_route=-1 -> DID NOT work!
