As you didn't change anything I won't change my post:
How is it possible that you still haven't solved the USB 3.0 isssues?
- recognising USB 3.0 HW on startup fails almost ALWAYS!!!
--> "workaround": unplug the stick / pen drive, restart, push F10 and hope the Nuc finds it next time
- booting up from a USB 3.0 fails in 80% of the cases
Please solve this problems at last! I'm very dissapointed with this product!
I am sorry to hear you still have problems with your NUC.
I would like to try to replicate your issue but I need the NUC model number. Please reply back with the AA or SA number of your NUC.
