DualRole USB 3.0 to 3 Port USB Hub with Gigabit Ethernet Port

This product is a power-leeching liar: hub reports as self-powered,

yet both hub and NIC are powered by host VBUS.
When auxiliary power supply is used, then downstream ports are
switched to sourcing from DC inlet jack J1.

Hardware has capability to detect power supply presence:

J1 has a switch pin, leading to U3 (VLI hub controller pin 47)
and to Q1 (pin 1. Q1 might be a transistor / logic gate.
pin 3 leads to host VBUS (5V), pin 2 leads to ground plane).
When DC barrel plug present, J1 switch is OPEN, pin voltage rises to 4.4V from Q1.
When NO plug present, J1 switch is CLOSED to ground/0V.

U8 might act as power switch, connect downstream receptacle

power pins to one of: upstream USB VBUS, or J1.

Board label

Board label silkscreen mark: "IA-HEB2-H100", "2012-11-19" (likely design date)

"1428" in seven segment style (likely circuitboard manufacture date 2014 week 28)
MAC address of specimen is 00:24:9b:11:24:e3,
which resembles USB serial number 0000249B1124E3.
