Seems to work correctly, VBUS gets switched as expected. Note that the hub advertises itself as:

Bus 008 Device 004: ID 17ef:1039 Lenovo USB3.0 Hub             
Bus 007 Device 004: ID 17ef:103b Lenovo USB Billboard Device   
Bus 007 Device 002: ID 17ef:103a Lenovo USB2.0 Hub

uhubctl sees it as:

Current status for hub 7-1 [17ef:103a VIA Labs, Inc. USB2.0 Hub 000000000, USB 2.10, 5 ports, ppps]
  Port 1: 0100 power
  Port 2: 0100 power
  Port 3: 0103 power enable connect [2e8a:000a AAAFNRAA Central Scrutinizer E6616408435D832B]
  Port 4: 0100 power
  Port 5: 0503 power highspeed enable connect [17ef:103b VIA Labs, Inc. USB Billboard Device 0000000000000001]

What's on the 5th port is a mystery to me.
