2.2 Usage Notes

  • Keeps the Power Flowing. Whether you’re taking a short break or are done for the day, the OWC Thunderbolt Hub keeps you powering ahead. No matter if your machine goes into sleep mode, the Thunderbolt 4 and USB ports continue to power and/or charge connected devices.
  • All ports support hot-plugging. To ensure no data is lost, always eject or unmount any connected storage devices from your operating system before disconnecting them from your hub (or before disconnecting the hub from the host computer).
  • All downstream Thunderbolt ports on this device provide up to 15W bus power for compatible Thunderbolt and USB-C peripherals.
  • Thunderbolt device chains can support up to six Thunderbolt devices, thus a total of five additional Thunderbolt devices can be chained to the Thunderbolt Hub. It is not possible to chain five devices to each available Thunderbolt 4 port. In addition, a Thunderbolt 4 or Thunderbolt 3 display (or a display connected via a USB-C display adapter) can be added to the end of a device chain.

Display Notes

  • Note that it is possible to connect other types of displays such as HDMI and DisplayPort to an available Thunderbolt 4 port, so long as you have the appropriate USB-C display adapter (e.g. a USB-C to HDMI cable, or a USB-C to DisplayPort cable).
  • The Thunderbolt Hub supports DisplayPort 1.4 capabilities, so long as the connected host and display also support it. For use with a single display, Thunderbolt 4 supports resolutions up to 8K @ 60Hz or 4K @ 120Hz. For dual display configurations, the two applicable ports support up to 4K @ 60Hz.

3.1 Troubleshooting

Begin troubleshooting by verifying that the power cable is connected to the OWC Thunderbolt Hub and to a power source. If the power cable is connected to a power strip, make sure that the power switch on the strip is turned on. Next, verify that both ends of the Thunderbolt 4 cable are properly plugged into the computer and the hub. If the hub is still not working properly, try using a different Thunderbolt 4 cable or using another Thunderbolt port on the computer.

You can verify if the hub is communicating with the computer by opening System Information and clicking on the ‘Thunderbolt’ category in the sidebar. If the hub is seen by the computer but one or more connected devices are not, troubleshoot each device individually. If problems persist, please contact OWC Support.
