 Is this 7-port as in the subject, or 4-port as in the patch?
 My 7-port NEC says:
 ugen3.8: <product 0x0050 vendor 0x0409> at usbus3, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE
 
 Those are another 7-port, but I don't know the vendor:
 ugen3.9: <USB 2.0 Hub [MTT] vendor 0x1a40> at usbus3, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE
 ugen3.11: <USB 2.0 Hub [MTT] vendor 0x1a40> at usbus3, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE
 It is a Sedna 13 port hub containing both of them.
 I thought those were NEC chips too, but ID looks very different and
 I can't easily open it because of the installation place.
