Power and data settings

Port tab view - power and data settings

The left side of each port tab view contains power and data settings for the port. At the top are the port name and upstream toggle.

Port name (editable ) - friendly port name used by HubTool and ControlRoom)

Upstream toggle - indicates and selects which port is in upstream mode and able to connect to a host

Power and data toggles

Below the port name are the power and data toggles. Click the carats () to expand the view.

Power and data toggles

Toggle name		Enables and disables
Port		Port data and power
Power		VBus
Data		All data
	HS	USB 2 (High Speed) pins
	SS	USB 3 (Super Speed) pins
CC		Both CC pins
	CC1, CC2	CC pins individually
Vconn		Vconn pins
	Vconn1, Vconn2	Vconn pins individually

Data and power status, power mode

Below the toggles are data mode, data rate, and power role status indicators, followed by the power mode menu. The virtual LED color corresponds to the color of the real LED indicators on the USBHub3c front panel.

Data and power status

Data mode	Upstream (to host)	Green
	Downstream	Red
	Control port	White
Data rate (highest speed)	USB 2	Yellow
	USB 3 (5 Gb/s)	Green
	USB 3 SuperSpeed+ (10 Gb/s)	Blue

Power modes

Summary abbreviation	Power mode	Definition	Virtual LED
N/A	Disabled	Power off	Black
SDP	Standard Downstream Port	Host not present or USB 2 data lines disabled:    5 V, 100 mA Host present and USB 2 data lines enabled:    5 V, 500 mA	Red
CDP/DCP	Dedicated Charging Port (CDP/DCP)	Host present and USB 2 data lines enabled:    CDP mode, 5 V, 1500 mA Host not present and USB 2 data lines enabled:    DCP mode, 5 V, 5000 mA	Red
QC	Quick Charge™	Qualcomm® Quick Charge™ 2.0 and 3.0 fast charging, requires Quick Charge feature license	Green
PD	Power Delivery	USB-PD 2.0 and 3.0 compliant Pro model – PD 3.0-20 V, up to 5 A, supports USB PD-PPS and QC 4+ Lab model – 5 V fixed, up to 3 A	Blue
PS	Programmable Power Supply	Manually set 2.8 V – 21 V and 0 A – 5 A, requires VBus validation feature license	White

VBus voltage and current control

(Requires VBus validation add-on)

Manually set VBus voltage and current

When Programmable Power Supply (PS) mode is enabled, VBus voltage setpoint and current limit can be set directly, transforming the port into a programmable power supply capable of supplying up to 100 Watts.

In Power Delivery (PD) mode, the user-set values override the negotiated values. However, PD negotiations are still active and PD events or errors can trigger re-negotiation, which will replace the user-set values. These values should only be changed when the power role is set to sourcing.

Setting	Value
Voltage setpoint	2.8 V – 21 V
Current limit	0 A – 5 A

Warning

Can damage attached equipment!

Voltage and current display

Shows a graph of the VBus and VConn voltage and current of the port.

VBus and VConn panel view

Clicking on the port graph pops up the Port Plots window with a larger rolling strip chart showing all ports. Click the carat ()to expand each port chart. If PD logging is enabled, PD messages will be marked in yellow.

Port Plots window

Left vertical axis – voltage (V)

Right vertical axis – current (A)

Horizontal axis – time (s)

By default, the plot will be scrolling. To stop scrolling, drag the dark gray scroll bar to the left. To enable scroll-to-zoom, click the desired axis.

Device descriptors

If Options > Port Mapping is selected, when a device is attached to a downstream port, its descriptors will scroll at the bottom of the port panel. Click the carat () to expand:

Descriptor table

Descriptor	Content
VID:PID	16-bit vendor ID and 16-bit product ID
Product	Product name string
Manufacturer	Manufacturer name string
