Independently control VBus and data connections on each port of the USBHub3+

More control than just on and off

Enable and disable VBus, all Data, High Speed or Super Speed connections

In addition to turning ports on and off, the USBHub3+ can also independently enable and disable Voltage and Data:

  • Vbus
  • All Data
  • High Speed data (480 Mbps)
  • Super Speed data (5 Gbps)

We'll be working interactively using the Brainstem API in a Python console so you can see the results line-by-line.
