I suggest you to reinstall the OS with UEFI option enable, and let me know the outcome.
Please keep in mind that this OS is not in the list of supported operating system.
I have had this same problem, but it and others are not present with BIOS 0024.
It is installed in UEFI mode. The eMMC has a GUID partition table and fast boot mode is working.
Saying "Debian-like Linux' are supported, but Red-Hat-likes are not" is just plain nonsense!
Why should I downgrade the BIOS if the newer version fix issues with Linux?
I guess it'S due to kernel 3.10 - I will install elrepo yum repository and try kernel 4.4 (package kernel-lt).
EDIT: Yes, it'S the old kernel version. The USB controller was not added to the list of switchable controllers.
Kernel 4.4 supports EHCI/XHCI switching for this controller and everything is fine.
It's a shame, that Intel does not correct their BIOS and that this change was not properly backported to kernel 3.10 by the community!
Use newer if you think it fixes something then. My experience has been very much the opposite, the newer BIOS releases break multiple things with Linux and the Intel support here is of no help whatsoever, no matter how many cases I have opened.
Thanks for the feedback, nice to know that your NUC is working properly.
