Thanks for coming back to the communities.
I understand you are trying to utilize USB 2.0 ports but they are not recognized by USB devices.
Please make sure have installed the latest BIOS for your computer:
File name:
WYLPT10H.86A.0025.EB.EXE
Also, check USB legacy mode and set this to enable and try again.
Please bear in mind that your operating system has not been validated for your NUC model. Intel recommends contacting the Linux community for assistance:
