Hi Steve,

Try this:

static void
ubsa_sierra_unlock(struct usbd_device *udev)
{
	usb_device_request_t req;

	req.bmRequestType = UT_WRITE_VENDOR_DEVICE;
	req.bRequest = 0x0b;
	USETW(req.wValue, 0x0001);
	req.wIndex[0] = 0;
	req.wIndex[1] = 0;
	USETW(req.wLength, 0);

	if (usbd_do_request_flags
	    (udev, NULL, &req, NULL, 0, NULL, 1000)) {
		/* ignore any errors */
	}
	return;
}

static int
ubsa_probe(device_t dev)
{
        struct usb_attach_arg *uaa = device_get_ivars(dev);
        const struct ubsa_product *up = ubsa_products;

        if (uaa->usb_mode != USB_MODE_HOST) {
                return (UMATCH_NONE);
        }
        if (uaa->iface) {
                return (UMATCH_NONE);
        }
        if ( uaa->vendor == USB_VENDOR_SIERRA && uaa->product == 0xfff )
        {
	  ubsa_sierra_unlock(uaa->device);
	  return (UMATCH_NONE);
        }
        while (up->vendor) {
                if ((up->vendor == uaa->vendor) &&
                    (up->product == uaa->product)) {
                        return (UMATCH_VENDOR_PRODUCT);
                }
                up++;
        }
        return (UMATCH_NONE);
}

If it works, maybe you can send a complete patch including those entries you 
added to usbdevs ?
