Hi,

Got a Zotac ID91 mini-PC
(http://www.zotac.com/products/mini-pcs/zbox/product/zbox/detail/zbox-id91-1.html)
recently and installed FreeBSD (10-STABLE, r267719) on it.

Hooking up my Mediasonic ProRaid HUR3-SU3S3 to the USB3 ports however
showed the drives up at only USB2.0 speeds:


Hi,

What does "pciconf -lv" say?

I see you have a Lynx Point USB 3.0. They are a bit troublesome. Have you played with the port routing mask under hw.usb.xhci ?

--HPS


pciconf -lv said (as attached previously):

xhci0@pci0:0:20:0: class=0x0c0330 card=0xb20619da chip=0x8c318086 rev=0x05 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Lynx Point USB xHCI Host Controller'
    class      = serial bus
    subclass   = USB

I set hw.usb.xhci.xhci_port_route=-1 in /boot/loader.conf but it did not seem to have any effect as another poster has reported. Looking at xhci.c:

        if (sc->sc_port_route != NULL) {
                /* Route all ports to the XHCI by default */
                sc->sc_port_route(sc->sc_bus.parent,
                    ~xhciroute, xhciroute);
        }

It seems that if xhciroute=-1 as set by the tunable, the code above will actually call sc_port_route() with set=0, clear=~0. Maybe that's not what's intended?

Anyway I tried again with hw.usb.xhci.xhci_port_route=0 and then I did see the initial setting of the mask:
Jul  1 00:14:14 z2 kernel: xhci0: Port routing mask set to 0xffffffff
Jul  1 00:14:14 z2 kernel: usbus0 on xhci0

However, not long after that, the port fails and the mask is reset to 0.

I guess this system is lost cause then...
