nuc7i7bnh randomly crashing - suspecting USB issue




We have a few nuc7i7bnh connected to USB 3.0 machine vision cameras with Ubuntu 18.04.

Some systems are randomly crashing. We don't if it's memory related or USB driver low-level related. Here is what we see in the logs:

kernel: [ 4080.757907] xhci_hcd 0000:00:14.0: WARN Cannot submit Set TR Deq Ptr

Has anyone encountered this type of issue? If so, have you been able to resolve it?

Any help is greatly appreciated.

Hello alexandrebustamante: Thank you for joining the Intel® communities support.



As you can in the following link, Intel validated the NUC to work with Windows® 10 and all the drivers that we have available in our web site, belong to that operating system:



In this case, I encourage all the peers viewing this conversation, that if they have further suggestions about this subject to post all the comments on this thread.
