IS This signal detects the state of the upstream bus power.
When designing a detachable hub, this pin must be con-
nected to the VBUS power pin of the upstream USB port
through a resistor divider (50 kΩ by 100 kΩ) to provide
3.3 V.
For self-powered applications with a permanently
attached host, this pin must be connected to either 3.3 V
or 5.0 V through a resistor divider to provide 3.3 V.
In embedded applications, VBUS_DET may be controlled
(toggled) when the host desires to renegotiate a connec-
tion without requiring a full reset of the device.
