To remedy any port issues with your Satechi Hub/Adapter/Dock and your host computer, we recommend restarting or shutting down your host device. 

Please ensure that your Satechi Hub/Adapter/Dock is disconnected from the host device and all devices are unplugged. 

For Intel MacBooks, We recommend an SMC reset. This helps reset the SMC (System Management Controller), 

which resets the MacBook's USB-C ports that connect to any power consumption devices (such as your Satechi Adapter). To do this, please complete the following:

For M1/M2 iMacs, Mac Minis, or MacBooks 
These Macs do not have an SMC, but there is a way to do a reset similar to the SMC reset:

1. Shut down your Mac.
2. Once the computer is completely shut down, close the lid of the MacBook.
3. Wait 30 seconds, then open the lid and press the power button to turn on your Mac.

For Windows:

To troubleshoot most Windows USB connectivity issues, you can try uninstalling the drivers for USB. (these drivers

 are automatically reinstalled after a reboot) 

To do so, open Device Manager. You can do that by pressing Windows Key + X and choosing Device Manager from the list. Locate the device driver (under Universal Serial Bus controllers) and right-click the ones regarding Thunderbolt 3 Hubs. Choose Uninstall device to remove the driver.

Once you uninstall the drivers, power cycle your device.

We hope this helps!
