Please note that the USB4-HUB3A is officially supported in conjunction with Windows PCs that have Thunderbolt 4 technology built-in.  

While the hub can work with some Thunderbolt 3 Windows PCs, the level of functionality of the hub when used with a Thunderbolt 3 Windows PC cannot be guaranteed. 

That said, we have had reports that the hub needed to be manually Approved within the Intel Thunderbolt application when used with some Windows Thunderbolt 3 systems before USB devices connected to the hub would function properly.  

If USB devices are not working properly via the hub, please check the Approval status and manually Approve if necessary.  

We have a video that demonstrates how to ‘Approve’ the device using the two different types of the Intel software (known as either the ‘Intel Thunderbolt Software’ or the ‘Intel Thunderbolt Control Center’) here → https://youtu.be/aRN2aEzmsyo
