@Dominik In relation to below, I have attached a picture of my NUCs. the usb looks well seated and i have tried numerous times to adjust the cables as well.
From what I understand current intel NUCs “don’t have any option in BIOS to disable xHCI, this was removed in later devices due to recent operating systems natively supporting USB3.0”

I have also gotten another limesdr and I have a similar problem. It doesn’t work when i use a different USB 3.0 extension cables. I have a steady green light on one side and a blinking red light on the other
side when i connect the sdr I now have 3 different USB 3.0 extension cables and 2 limeSDR’s.
I just can’t figure out what the cause of the problem is at the moment.

Thanks for the information
