Thank you for contacting the Intel® Communities.
Here you can find some troubleshooting that you can perform:
-Please go to your BIOS >Advanced>Devices>USB and make sure the ports are enabled.
-You could also perform a BIOS recovery to the version 0353 which would be the latest for your unit. Recovery BIOS Update Instructions for Boards and Kits
-Uninstall the USB drivers from the device manager and let Windows install the default drivers.
-Also, make sure you have installed the Chipset driver and the ME driver, added below.
-If you connect a device to charge, maybe a phone, are you able to charge it with the rear ports?
BIOS file: Download BIOS Update [RYBDWi35.86A]
I look forward to your outcome on this.
thank you for your response Estaban.
I have updated the BIOS to v353 as per the link provided. This did not address the problem.
I uninstalled the drivers from Windows 10 and allowed Windows to install the default drivers. This also did not work.
I installed the Chipset driver from the link you provided - no effect.
I then uninstalled and reinstalled the ME driver from the link provided without success.
I checked the advanced settings in the BIOS. They indicate that 6 USB ports are enabled. USB Legacy was turned on, portable device mode was set to s3/s4/s5 enabled or something like that (screen shot I took did not capture the value, so based on memory). xHCI mode is set to 'Smart Auto'. I tried with USB legacy both checked and unchecked - no change.
I have plugged a phone into each of the 4 ports, only the front 2 ports will charge it.
When I am in the advance BIOS screen (to eliminate Windows 10 as a variable), again only the front 2 ports will charge my phone and recognize my usb keyboard and PQI 4Gb thumb drive.
Do you have any other suggestions?
A possible way to check that this is not related to the OS would be the following:
1. Download and create a bootable USB device of Ubuntu.
2. Access the try option for Ubuntu and test the rear USB ports.
Ubuntu has the option to just "try" the OS, so you won't loose any data and you would't have to install the OS.
Once you reboot and remove the stick, it should boot to Windows 10* as usual.
If after performing this you are not able to use the rear USB ports, my recommendation would be to verify the warranty on your product.
Note: The first 30 days after the purchase of the unit are covered by the place of purchase, if more time has passed you can request it with Intel Customer Support (Contact Support)
I had a similar issue with a NUC5i5RYK, running Linux/Mint 17.3; I tried various BIOS versions, up to 354. None helped. I sent it back, but the replacement nuc that I got is missing a crucial post and screw (to hold the far end of the SSD card). How do I contact INTEL so they can send me what they forgot to include? The support phone number is well hidden.
I am sorry to hear this happened with your replacement.
You can contact them in the following link: Contact Support
Please select your region and then NUC, phone support would appear after selecting that.
