I recently noticed the speed down of usb 3.0.
The worst thing is that I have an external hard drive with blue light if it acts in usb 3.0 and white light if it is usb 2.0
In another pc when connecting it turns blue and white in the nuc, so in nuc it acts as 2.0
Recientemente he notado la bajada de velocidad de usb 3.0.
Lo peor es que tengo un disco duro externo con luz azul si actua en usb 3.0 y luz blanca si es usb 2.0
En otro pc al conectarlo se enciende azul y blanca en el nuc, osea en nuc actua como usb 2.0
Now the same HDD usb 3.0 before and after the last bios.

Thank you for joining the Intel® NUC Community. I am sorry to hear you are having issues with the ports speed.
Please let me double check this matter, I will update the thread as soon as possible.
Thanks for your interest, I take advantage to give more information about the problem.
I have been able to verify that all my usb 3.0 units are now being recognized as 2.0, I send you screenshot where this is confirmed with an application like Rufus.
In this case, it looks for connected pendrive drives and discards the hard disks not before without noticing that it finds them working at slow speeds.
Just comment that all this external hardware was previously recognized correctly and recorded very good transfer values so it is not an incompatibility problem.
I hope all this information will help you find a solution soon. I am very satisfied with the performance of your Nuc and has fulfilled all my expectations on topics such as 4K and versatility in general.
A greeting from Spain
