I have a work around.
I've connected both of my optical drives to my hub using a USB 2.0 cable. Both drives are now working correctly and do not produce a random unrecognized device error while the NUC is powered on. And the USB hard drive, using a 3.0 cable, not longer disconnects randomly.
I have a couple of questions for you:
Is the Blue Ray drive a native USB3.0 unit from factory or it is an internal SATA drive that you installed in a SATA-to-USB3.0 external enclosure?
You said that you tried a Samsung M.2 drive through USB3.0. This means that you are using an external M.2-to-USB3.0 enclosure, is that correct?
If the answer is yes for both questions the common fact that I see is that you are using enclosures to connect to USB3.0. There is a big possibility that this is a compatibility problem with the enclosures or that the USB3.0 controller of the NUC is not identifying the devices properly due to the conversion from SATA to USB3.0 and M.2 to USB3.0.
I know that you already found a work around but it will be good idea to test native USB3.0 devices to compare the results.
In any case it won’t be bad idea to have the NUC drivers and BIOS up to date.
The latest BIOS (v0350) for this unit can be downloaded using the following link:

To download the latest drivers visit the following URL, select “Drivers” under “Download type” and pick the operating system version you are using;
The Bluray burners are SATA units installed in Chinese eBay SATA to USB 3.0 enclosures. I've since ordered and connected the same type hardware but as a complete package from a company called Pawtec in CA (from eBay). That drive works fine using USB 3.0. Apparently there's an issue with the Chinese USB 3.0 chipset in the first enclosures I ordered although they're fine using USB 2.0 cables.
You are correct concerning the M.2 drive in an external enclosure. That, too, is working fine now with USB 3.0.
I'm running the latest available BIOS and USB drivers from the website.
I've ordered another enclosure from Pawtec in hopes that the other Bluray burner will work using USB 3.0.
I don't have any native USB 3.0 burners to connect with - too much money invested in enclosures that are not so sweet. :>)
Thanks for the reply.
Thank you for the information.
I hope the new enclosure works better.
Keep me posted.
