Overview
This Thunderbolt™ 3 to USB 3.1 controller adapter offers twice the performance of a traditional 4-port USB 3.1 hub, enabling you to connect a wide range of devices to your Thunderbolt 3 laptop. With dedicated USB buses, the controller adds four USB ports - two USB-A (5Gbps), one USB-C (10Gbps) and one USB-A (10Gbps).
High-performance 10Gbps ports
The two 10Gbps ports are useful for accessing high-performance, bandwidth-hogging devices such as storage arrays, 3D scanners, audio-video capture and broadcast devices, and external SSD drives. The Thunderbolt 3 port can also be used for connecting a second 10Gbps USB-C device.
When only one port is being accessed, the full dedicated 10Gbps is available. If both 10Gbps ports are being accessed at the same time, the bandwidth being provided to each device will be 5Gbps.
Dedicated 5Gbps ports
The two 5Gbps ports can provide 5Gbps of bandwidth to each device simultaneously, making it ideal for devices such as portable hard drives. You can also connect low-bandwidth devices such as USB flash drives.
The front USB-A port supports both data and charging. The adapter does not need to be connected to a Thunderbolt 3 computer in order to charge your mobile devices.
Extend your workstation
The adapter features a second Thunderbolt 3 port that you can use to connect an additional display to your laptop (a USB-C video adapter may be required). The port can also be used to connect additional Thunderbolt devices, daisy-chaining up to six devices in all.
The TB33A1C is backed by a StarTech.com 2-year warranty and free lifetime technical support.
Applications
Connect high-bandwidth devices such as such as storage arrays, 3D scanners, audio-video capture and broadcast devices and external SSD drives to the 10Gbps ports
Add two 10Gbps ports (one USB-A and one USB-C) and two 5Gbps USB-A ports, without losing the Thunderbolt 3 port on your laptop
Connect multiple bus powered SSDs with dedicated bandwidth for faster read write access
Connect low-bandwidth and legacy USB devices such as a keyboard, mouse or USB flash drive to the 5Gbps ports
Connect a Thunderbolt 3 laptop to your existing USB 3.0 devices, such as USB 3.0 docking station, printer, hubs

Frequently Asked Questions
Before You Buy
Components
Thunderbolt™ 3 is the latest version of the Thunderbolt standard for connecting computers and electronic devices. It is capable of the following:
- Total bandwidth up to 40Gbps. Data transfer speeds are dependent on the other features that you are using in your setup.
- USB 3.1 Gen 2 support.
- 4K 60Hz video on one or two separate displays.
- 5K 60Hz video on a single display.
- A 10 GbE network connection between two Thunderbolt 3 compatible computers.
- Up to six devices daisy-chained from a single Thunderbolt 3 port.
- Alternate modes, such as DisplayPort Alternate Mode (DP Alt Mode).
- Bi-directional power delivery up to 100W (not all Thunderbolt 3 devices support power delivery).
USB-C and Thunderbolt 3
Thunderbolt 3 uses the USB-C connector, but not all host connections, cables, and devices with a USB-C connector support Thunderbolt 3. This means that a USB-C device is compatible with a Thunderbolt 3 host connection, but a Thunderbolt 3 device is not compatible with a USB-C host connection. Therefore, it is important to know whether you have a USB-C or a Thunderbolt 3 host, cable, or device.
To determine if your component is a Thunderbolt 3 device, look for the Thunderbolt 3 symbol (shown below). USB-C devices do not include this symbol. For more information about USB-C, see the following FAQ: https://www.startech.com/faq/usb-c-port-capabilites.
Thunderbolt symbol: https://sgcdn.startech.com/005329/media/products/gallery_large/TBLT3MMXM.B.jpg.
Backwards compatibility
If you use an adapter, Thunderbolt 3 host connections are compatible with Thunderbolt 1 and Thunderbolt 2 devices. You can use the StarTech.com TBT3TBTADAP to make a Thunderbolt 3 host connections backwards compatible.
Thunderbolt 3 devices are not backwards compatible with Thunderbolt 1 and Thunderbolt 2 host connections.

Although the Thunderbolt™ 3 standard is capable of data transfer speeds up to 40Gbps, not every cable can support this bandwidth. For example, cables over a certain length or made with certain materials are only capable of data transfer speeds up to 20Gbps.
To confirm the capability of your Thunderbolt 3 cable, refer to the information provided by the manufacturer. StarTech.com lists the capabilities of the Thunderbolt 3 cables on the individual product pages.
There are two different Thunderbolt 3 cable symbols: the 20Gbps symbol and the 40Gbps symbol. The 20Gbps symbol is composed of the Thunderbolt 3 symbol, and the 40Gbps symbol is composed of the Thunderbolt 3 symbol and the number three. These images are shown below.

To use a Thunderbolt 3 adapter to output to a display at 60Hz, your monitor must support the refresh rate and you need to set the monitor to work at 60Hz. By default, most monitors are set to DP1.1, which will not work with this Thunderbolt 3 device when you use a display at 60Hz. In most cases, you need to set your monitor's DisplayPort settings to DP1.2.
To resolve this issue, use the buttons on your monitor to change the DisplayPort settings to DP1.2. For more information about changing your monitor settings, refer to the website of the manufacturer of your monitor.
