For such a problem, users reported it to Razer support. And as I mentioned, Razer also provides user Support. Fortunately, Razer mentioned possible fixes for that USB not working issue.

Restart the Thunderbolt 4 Dock USB Setup

The first thing you should do is restart the system. It is because of the overhaul that it is working at such a fast pace. Sometimes the processor can’t process inputs and USB ports don’t work. For this thing, you need to restart the entire setup, so USB ports resume functioning. I expect you to know how to restart it. But if you have questions, follow the following steps.

Simply detach the Thunderbolt 4 cable
After that, turn off the power on both the Razer core and blade system.
You will need to unplug the electrical cable from the Razer core to disconnect the power and wait for 30 seconds.
After that, reconnect the electric core and restart the core and razer blade.
Now plug the devices into the ports that weren’t working previously.
That’s all there is to it. The PC detects all USB ports and the issue is solved.

Try another USB port

As a common practice, you should use another USB port if one USB port does not respond. But note that we are not neglecting the non-working port. Instead, if other ports are functioning, you can update the port and fix the non-working port with that new update. I know updating port drivers seems difficult and confusing for everyone.

The reason is, your Pc USB driver does not recognize the connected device and it seems like Razer Thunderbolt 4 dock USB not working. You still get the same issue even after trying the above two fixes. We recommend updating your device drivers. To do that, follow the steps below.
