Another troubleshooting step is that you can check on BIOS the USB setting in regards of the powered USB port. Please get in to the BIOS - Advanced - Devices and under the USB tab please check the information on the left hand side, there should be an option that says "Portable Device Charging Mode" with different options:
- Off: With that selected the USB will not respond neither with the NUC on nor of
- Charging in S3/S4/S5: With that selected the USB will have charging capabilities if you send the computer to sleep (S3), hibernation (S4) or shut down (S5)
- Charging Only: USB Port will always provide extra power but cannot be used to transfer data.
Please make sure to have the second option selected and then save changes by pressing F10. After that you can test if the USB is powered with the NUC off. If the issue persists you can rollback to the version that you had installed before. You can do the rollback in the exact same way as you did the BIOS update.
As a friendly advice, if the NUC is working fine we do not recommend to do any type of BIOS updates. The BIOS update is part of our troubleshooting steps and it is used only when needed unless you really need it for example to support a hardware component, which at this point the NUC does not have any problems with incompatible parts that require a BIOS update.
Please let me know if the suggested workaround resolved your issue.
