Internal USB3 motherboard header performance and stability on NUC7i7DNBE much worse than external USB3 port

[Russell]

Hello,

I'm having some issues with the internal USB3 motherboard header on the NUC7i7DNBE model.

I am connecting a USB3 vision camera (Ximea) to the board via the internal motherboard header USB3. The device keeps resetting and transfers data much slower than when using one of the external USB3 ports.

The external USB3 ports don't have any of the issues and work fine.

I'm using the recommended Gorite USB3 NUC header cable to Female A port from here: https://www.gorite.com/dawson-canyon-usb-3-0-female-to-10-pin-header-cable

I was wondering if this is a known issue, or if Intel have some guidelines for use of the internal USB3 port?

Thanks

Russell

Hello Russell, Thank you for posting in the Intel® Communities Support. In reference to your question from our side there are no known issues reported with the internal USB 3 header. Just to let you know, Intel® have not validated the cable that you are using so we cannot answer if there is an issue with it: http://compatibleproducts.intel.com/ProductDetails?prodSearch=True&searchTerm=NUC7i7DNBE# Do you have the option to test another cable? What is the specific model of your Ximea camera? Which Windows version are you using? Are you using the proper memory RAM with this unit? It should be DDR4-2400 1.2V SO-DIMM: https://ark.intel.com/products/130394/Intel-NUC-Board-NUC7i7DNBE Did you updated the BIOS in the NUC? The latest version is 0060: https://downloadcenter.intel.com/download/28465/BIOS-Update-DNKBLi7v-86A-?product=130394 Regards, Alberto R.

Hi Alberto,

I'm in the process of having a custom cable produced for the internal USB3 port as I'm not sure if the GORITE one is a proper shielded USB3 cable. I was hoping to post an update when I get it.

Regarding my current setup, the Ximea camera is: MC089MG.

I'm running Ubuntu 16.04.

I believe I am using the correct ram, my modules are: CT12174652 Ballistix Sport LT 8GB Kit (2 x 4GB) DDR4-2400 SODIMM.

I need to double check the bios but I upgraded to the most recent one at the beginning of January, so I think it would be the 0060 version.

Thanks

Russell

Hi Russell, Thank you very much for sharing those details. Yes, you are using the proper memory RAM for the NUC and also, as you mentioned, the BIOS version 0060 is the latest one available for the Intel® NUC Board NUC7i7DNBE. There should not be a performance difference between the internal and external USB ports, so please let us know the results of testing the custom cable. Regards, Alberto R.
