remout: Thank you very much for joining the Intel® NUC communities. We are sorry to hear that the NUC is not working properly in regard to the USB feature.
Besides the steps you already tried, we can try a BIOS update to the latest version: 0049 using the F7 method:
Even though you mentioned you updates all the drivers using our tool, we can also try to re-install the chipset and management engine drivers manually:
Did you test all the USB ports on the NUC?
Any further questions, please let me know.
This is going to sound odd but here goes. I'm a software developer, not a hardware guy, and have had my NUC about 6 months. It's had two minor issues. First the one mentioned in my post. The other issue was it would always turn back on about 10 seconds after shutting it down.
Not long after receiving your reply to this thread, both problems disappeared. Here's what changed:
- Posted on this forum
- Downloaded the new bios, as you recommended, but did not install it.
- Installed a Logitech gaming wheel and pedal set, this filled up all my usb ports for the first time.
None of this makes much sense, but the unit is working great. Thank you for your help!
remout: Thank you very much for letting us know that information. Perfect, even though those steps are not the usual steps for this scenario, it is great to hear that the NUC is working great now.
Any other inquiry, do not hesitate in contact us again.
I'm back to having the same problems. To summarize:
1. NUC restarts sometimes after shutting down. Does it from Windows button and power shell shutdown.
2. Keyboard/mouse stops working with error "Last device plugged in not recognized" or something close to that. Unplug keyboard/mouse and it will work for a few minutes before it does it again.
Win 10 Pro
Have tried 2 different keyboards, one with external mouse and one all in one bluetooth setup. Both get the same error and stop working.
Update drivers many times
remout: Thank you very much for letting us know those results. We are sorry to hear the NUC is not working properly again.
At this point pretty much you tried all the troubleshoot steps that we recommend for this type of scenario, which is a BIOS update to the latest version and to re-install all the drivers including chipset and management engine, besides testing the NUC with different peripherals and power supply. What we can try now if you have the option of course, will be to test it with just one memory stick, with each stick, just to rule out a possible problem with one of them, also to re-install Windows will be another step to do. If you have the option to use a different hard drive or SSD will be another option to try as well.
If the problem persists after that, then the next thing to do will be to replace the unit, please get in contact with Intel directly to confirm if the unit is eligible for replacement:

Any questions, please let me know.
I had tried running on one of the two, 16g, memory sticks without the problems going away. This time I swapped the memory sticks, only running on one at a time. I've now been running for two days without any mis behavior.
Its's doing it again.
Have you tried preventing the USB hub from going to sleep?
Try going to the device manager in the control panel, select the USB root hubs and there should be a tab called "Power Management" Uncheck the option "Allow the computer to turn off this device to save power" and see if it solves your USB problem.
I tried catskinner's advice but it didn't help. I've sent the NUC back to intel for replacement.
