My bus layout looks like this:
ugen0.1: <XHCI root HUB 0x1b21> at usbus0, cfg=0 md=HOST spd=SUPER
(5.0Gbps) pwr=SAVE (0mA)
ugen2.1: <EHCI root HUB ATI> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps)
pwr=SAVE (0mA)
ugen1.1: <OHCI root HUB ATI> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps)
pwr=SAVE (0mA)
ugen3.1: <OHCI root HUB ATI> at usbus3, cfg=0 md=HOST spd=FULL (12Mbps)
pwr=SAVE (0mA)
ugen4.1: <EHCI root HUB ATI> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps)
pwr=SAVE (0mA)
ugen5.1: <OHCI root HUB ATI> at usbus5, cfg=0 md=HOST spd=FULL (12Mbps)
pwr=SAVE (0mA)
ugen6.1: <OHCI root HUB ATI> at usbus6, cfg=0 md=HOST spd=FULL (12Mbps)
pwr=SAVE (0mA)
ugen7.1: <EHCI root HUB ATI> at usbus7, cfg=0 md=HOST spd=HIGH (480Mbps)
pwr=SAVE (0mA)
