Yeah, but they have to be different endpoints on the XHCI controller
to reflect the SS/HS difference.

My simpler 4-port SS hub looks like this:

ugen0.2: <USB3.0 Hub VIA Labs, Inc.> at usbus0, cfg=0 md=HOST spd=SUPER 
(5.0Gbps) pwr=SAVE (0mA)
ugen0.3: <USB2.0 Hub VIA Labs, Inc.> at usbus0, cfg=0 md=HOST spd=HIGH 
(480Mbps) pwr=SAVE (0mA)

root:ernst:~:bash:4> usbconfig -u 0 -a 3 dump_device_desc
ugen0.3: <USB2.0 Hub VIA Labs, Inc.> at usbus0, cfg=0 md=HOST spd=HIGH 
(480Mbps) pwr=SAVE (0mA)

  bLength = 0x0012
  bDescriptorType = 0x0001
  bcdUSB = 0x0210
  bDeviceClass = 0x0009  <HUB>
  bDeviceSubClass = 0x0000
  bDeviceProtocol = 0x0001
  bMaxPacketSize0 = 0x0040
  idVendor = 0x2109
  idProduct = 0x2812
  bcdDevice = 0x9090
  iManufacturer = 0x0001  <VIA Labs, Inc.         >
  iProduct = 0x0002  <USB2.0 Hub             >
  iSerialNumber = 0x0000  <no string>
  bNumConfigurations = 0x0001

root:ernst:~:bash:5> usbconfig -u 0 -a 2 dump_device_desc
ugen0.2: <USB3.0 Hub VIA Labs, Inc.> at usbus0, cfg=0 md=HOST spd=SUPER

  bLength = 0x0012

  bcdUSB = 0x0300
  bDeviceClass = 0x0009  <HUB>
  bDeviceSubClass = 0x0000
