Hello,

We dev a HMI for a device (it's not our device we bought it) which embedded a NUC (NUC7i7DNB)
And our final customer ask us to add a function to enable/disable the power of NUC's usb front panel (which are deported on device front panel).

What we want :

Disable/enable specific usb port or the entire root hub power.

If we need to change bios setting from os and reboot to apply it, it's ok.

Additional infos :

There are no external device connected on ports when we want to do such command.

We need to completely remove power from usb port (we though they want to protect their device against "usb killer" attack, or such vandalism)

We can do it in the bios settings, but we want to allow the user to do it from the OS (Which is Ubuntu 18.04)

What we tried/saw :

- It's look like root usb on this NUC don't allow power switching (sudo lsusb -v)

     The hub 0 "Linux Foundation 2.0 root hub" (Bus 001 Dev 001) says : wHubCharacteristic 0x000a     No power switching (usb 1.0)

     The hub 1 "Linux Foundation 3.0 root hub" (Bus 002 Dev 001) says : wHubCharacteristic 0x000a     No power switching (usb 1.0)

- Despite this, we tried to send sendClearPortFeature(PORT_POWER) to all root hub's ports, after that, root hub Port Status said power on ports is away, but that false, +5V still present between pin+ & pin-

- We tried to unbind driver of hubs, without success

- It's write in USB2.0 specification  "The roothub provides the same functionality for dealing with USB topology as other hubs" (Chapter 10.2.8 Root Hub)

And  "This state (Powered-off) is supported for all hubs. A port transitions to this state in any of the following situations: From any state except Not Configured when the hub receives a ClearPortFeature(PORT_POWER) request for this port" (Chapter 11.5.1.2 Powered-off)

Did we miss something ?

Is it possible to do such operation from OS ? on this NUC ?

Thanks in advance

Alex

I've NUC8i7HVK on order. I would like a spare power supply and IR remote; supported under Windows 10. Can someone please help? Thank you.

Does anyone else have a 5 sec boot delay, from the time the power button is pushed to the time the Intel NUC logo appears?

There seems to be a configuration issue with the Hades Canyon, after the 5 sec delay it will boot to a screen which has "Setup" and "BBS" on the upper right corner. It then proceeds to the normal boot screen and booting windows.

The 6th and 7th gen NUC's didn't have this issue, they booted to Windows in less than 2-3 seconds, and that's without fast boot enabled.

I am on the 47 version bios with 32GB of Corsair RAM 2400Mhz, if that matters.

I have started to get the error message in the attachment, now and then. It comes randomly when I use a browser.

The drivers are the latest.

Any idea what this is?

Hi,

I bought a NUC Kit NUC7PJYH (https://ark.intel.com/products/126137/Intel-NUC-Kit-NUC7PJYH) and encountered an issue, the 8GB memories (4GB DDR4 2133 x2) I installed always run in single channel active mode. I've tried two different memory brands/types, no luck at all.

So what's wrong? Need help, thanks.

The guy named honoredshadow in comment seemed to encounter same issue.

Hello everyone,

I'm working with a intel NUC Board NUC7i3DNBE and want to use both of the M.2 slots on the board. But when I try to use the small M.2 slot the device is not recognized.

Several sources on the intel page: Intel® NUC Board NUC7i3DNBE 122501 shows that there are 2 M.2 slots available, a 2280 M-keyed slot and a 2230 E-keyed slot.

The product specification sheet: https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC7i3DN_TechProdSpec.pdf also show that the 'second' M.2 slot (the 2230 E-keyed) is available. There are remarks on several places that there will be a wifi card in this slot on kit's that use this board and that way this slot is not available for use. (I suppose that this means it is not available because it is already populated).

When I look in the bios under Advanced > Devices > PCI, I can see only 1 M.2 slot. I have a checkbox to disable this slot and it shows some information about the SSD that is present in this slot. It does not show the second M.2 slot.

When I take out the SSD from the 2280 slot the bios shows me that the M.2 slot is "Not Populated" and the device ID is "<FFFF:FFFF>".

I have searched for this and tried some things in the bios like switching on UEFI boot and legacy boot, enabling and disabling the WLAN and Bluetooth options in Onboard devices. I updated my bios to the latest version.

Why does the bios only show 1 M.2 slot while there are two on the board? Does it check if the device in the 2230 slot is the what otherwise would be the supplied wifi card? Any tips on enabling the second M.2 slot?

Thank you in advance!

Greetings,

Justin

bios это фигня, а вот жадности можно только позавидовать, даже обновить пустой нук нельзя, нет места, зато бестолковых игр напихали. обновление уже 5 часов ставит, всего 19%, жесть полная. и результат после 6 часов failed. желаю вам того же))

I have Windows 10 64 bit installed on my Intel Nuc NUC8i7HVK. All drivers were downloaded from this site Downloads for Intel® NUC Kit NUC8i7HVK  and installed. NUC is connected to Yamaha A3070 receiver and then to Sony TV Oled A1. Belkin Ultra High Speed 4K HDMI Cables used for both connections.

PowerDVD 18 can't play HDR videos, saying that my TV can't play HDR.

Please help me with this issue. Thanks.

Hi folks,

my nuc5i3ryh runs as a HTPC with kodi and vdr. It automatically goes to sleep (S3) when there's no activity. It either wakes up by timer, IR  remote, WOL or simply the power button. The IP is static on the wired interface and wifi is disabled.

For a long time now I have an annoying issue: randomly the network is not working after resume. Sometimes it's every time, sometimes just every second time and sometimes it just works smoothly for days. Here's what I tried so far without improvement:

• Keep the BIOS updated
• Change the router
• Change the cable
• Try different power saving options in the BIOS (PCI related etc.)
• Loaded the network card module (e1000e) with specific option (such as "options e1000e SmartPowerDownEnable=0")
• Changed the linux distro (ubuntu 16.04 to 18.04; now it runs Debian Stretch)
• Reload network adapter and whole network stack on resume

This is how the system logs, when the interfaces fires up correctly:

Sep 14 19:40:31 nuc5i3ryh kernel: e1000e: EEE TX LPI TIMER: 00000011

Sep 14 19:40:31 nuc5i3ryh kernel: e1000e 0000:00:19.0: System wakeup enabled by ACPI

Sep 14 19:40:31 nuc5i3ryh kernel: e1000e 0000:00:19.0: System wakeup disabled by ACPI

Sep 14 19:40:34 nuc5i3ryh kernel: e1000e: enp0s25 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: Rx/Tx

And without network:

Sep 15 11:55:22 nuc5i3ryh kernel: e1000e: EEE TX LPI TIMER: 00000011

Sep 15 11:55:22 nuc5i3ryh kernel: e1000e 0000:00:19.0: System wakeup enabled by ACPI

Sep 15 11:55:22 nuc5i3ryh kernel: e1000e 0000:00:19.0: System wakeup disabled by ACPI

Sep 15 11:55:25 nuc5i3ryh kernel: e1000e: enp0s25 NIC Link is Up 10 Mbps Full Duplex, Flow Control: Rx/Tx

Sep 15 11:55:25 nuc5i3ryh kernel: e1000e 0000:00:19.0 enp0s25: 10/100 speed: disabling TSO

To me it very much looks like a hardware issue but I'm not willing to spend money on a new nuc while this one is running well (except for the standby).

Does the issue look familiar to you? Is there anything else I can try?

Regards, Uwe

I have been in contact with both LG support and MS support about this issue so far they have not been able to solve it.

I try with this forum as the issue seems to connected to the manufacture of the HW/PC.

I bought a external Blu-ray UltraHD drive, LG B60B10 to use with NUC8I7HVK.

I am aware of that Blu-ray UltraHD discs does not work (  :-(  ) with NUC8I7HVK, so that's not the issue.

The issue is that new Blu-ray disk is not possible to play with this combo. The symptom is sever reading problem and no video is shown.

I have tried with some older Blu-ray disks, about 10 years or older, and they can be played without problems.

This indicate that the copy protection scheme could be the problem. The new ones use besides AACS also Cinavia.

The old ones use only some versions of AACS.

The problems seems also be related to Windows 10.

Discs with DVD Video format can be played without problems.

I have tested the LG Drive on my three other computers.

Two different ASUS mini PC:s with W10 and neither can play new Blu-ray as the NUC.

On one I switched to another disk with W 8.1 and Blu-ray was possible with toplay.

So far in the investigation it seemed that problem only was connected to W10.

Then I tested with my oldest computer (10 years old) with a Gigabyte motherboard.

I tested with both W 10 and W8.1 and Blu-ray discs were possible to play with both versions!.

This leads to the conclusion that is not only problem with W10 it depends on the manufacture of the PC.

The first advice from MS was to check that I had the latest drivers, e.g. for USB.

But have the latest, I have with Intel update advisor and I also use  Driver Booster, which finds other driver updates.

So nothing  to do here.

To summarize.

The issue seems to be a combination of:

1. Windows 10

2. New Blu-ray discs

3. PC from some manufactures, e.g. Intel and ASUS.

My own opinion, with my tiny knowledge of the subject, is that some driver or driver(s) requires update.

Any similar experience or any ideas. Any comments from Intel?

Hello everyone.

TL;DR: I've enabled secure boot with custom keys and now can't enter visual BIOS.

So the full description of actions:

• I've generated DB keys for Linux EFISTUB kernel. Also I have an KEK key and my own Platform key. And also generated key to clear PK.
• After that I cleared default keys using Visual BIOS.
• As for next step I put all of my keys including additional key for booting windows ("MicWinProPCA2011_2011-10-19").
• After that using KeyTool.efi signed by my DB key I've added my db key an microsoft one.
• Then KEK signature and after that platform key that generated by me.

And after reboot I can't go into visual bios.  Also I can't boot any of my USB devices (even that one where I put signed keytool.efi in place of "EFI\BOOT\BOOTX64.EFI").

Only thing that works is windows EFI bootloader. I can succesfully boot into windows but I can't to boot anything else.

Also I've tried to clear CMOS using bios recovery with removing jumper:

• Placed firmware onto USB flash drive.
• Turned off nuc and plugged off.
• Removed battery connector.
• Waited for an 15 minutes or so.
• Plugged in USB stick and power cord.
• Pressed a button and nothing happened for an 30 minutes.

And important note is that I have no visual feedback at all with monitor connected to HDMI until windows bootloader starts.

I tried to clear CMOS with no M.2 drives and with single RAM stick. No success.

I found similar issue but I can't rollback since I can't go into BIOS.

My assumption is that intel visual BIOS requires some hardware driver ROMs which should be signed by some key that I don't have.

And thus neither recovery and Visual BIOS can't run some USB/VGA drivers and load them since can't verify signature.

So how do I get into visual bios or at least how do I clear platform key if I can't even boot keytool? Can I do that using Windows?

I have a NUC5i7RYH with Intel Ethernet Connection I218-V as the current ethernet driver.  Speedtest.net shows the download speed as around 300mb down.  Xfinity came out and tested their equipment and received 950mb down.  I have disabled the energy efficiency in the driver.  Any other suggestions to help improve the download?  Thank you!

Hi all,

I have recently had a bad experience with a brand new NUC5CYPH. In summary:

I added the RAM and SSD, and installed Windows 7. I was most of the way through downloading and installing about 200 updates when the machine started to behave a bit erratically: 100% processor use while simply searching for upgraded using Windows update, and very high RAM use, too. About an hour later I got a BSOD with random white dots all over it. When I tried to re-boot the NUC it simply power-cycled every few seconds (cooling fan switching on and off) without ever reaching the POST screen. At this point the NUC had been powered up for maybe only 8 hours total.

Troubleshooting:

There was no video output from VGA, or at least nothing my monitor could display. My monitor was detecting a signal and momentarily showed the selected resolution and refresh rate, but this was displaying nonsense (refresh rate of 11Hz instead of 60Hz). I have two VGA inputs on my monitor and both gave the same result. So far I have not been able to try it on another screen.

I removed the RAM and SSD and tried to boot from there, but I got the expected “three flashes” from the power light, indicating that there was a problem with the RAM. When I re-inserted that module, the original symptoms came back. At this point I decided it was dead and boxed it back up ready to return to the supplier.

I have since found that the RAM module I bought, while it does meet the physical and electrical requirements of the NUC, is not on the approved list

http://compatibleproducts.intel.com/ProductDetails/ExportPeripheralInfo?moduleName=Intel%C2%AE%20NUC&productType=Kits&productName=Intel%C2%AE%20NUC%20Kit%20NUC5CPYH

The RAM I bought is here https://www.scan.co.uk/products/4gb-(1x4gb)-corsair-ddr3l-so-dimm-value-select-pc3-12800-(1600)-non-ecc-unbuffered-cas-11-11-11-28-1

My question is: Could the “non-approved” RAM module I bought have been the reason my NUC failed so early? I know that the NUC is supposed to tell you if the RAM isn’t electrically compatible, and will refuse to boot, but I had no problems whatsoever until the BSOD.

Hi,

I recently purchased an Intel Nuc NUC7CJYS series,

Since the machine only ships with 30GB of storage i decided to put my own SSD into it and install the OS on that.

Heres the issue though

The machine recognises the drive when i get to desktop. But the BIOS doesnt allow it as a boot drive (though it sees it in the SATA port).

Also i have a windows 10 USB install drive in the back of the machine that is not detected by the boot menu or bios either.

If someone could lend a hand getting this sorted it would be really useful.

Our configuration:

NUC7i3BNK's with Windows 10 update 1803.

Synology diskstation servers running active directory

The users are in the domain using active directory with a profile.

When you log a user off, at the end of the log off process, the screen goes black.

If you access the workstation via VPN, you can see that the user is logged off and it looks normal from the remote view even though the screen is still black on problem machine.  From the remote view you can see that the mouse and keyboard are still functional and you can even log back in again but the screen remains black.  The only way to gain access to see the screen again is to restart the computer.

This does not happen all of the time.  Sometimes the log off is successful and the screen stays on.  Sometimes the profile gets corrupted.

In testing, I  created 2 new users and left them connecting to the domain using active directory but removed the profile.  The first time I logged out, I got the black screen and had to restart.  No profile corruption since no profile.  After restarting, I logged both users in on multiple identical machines over 50 times and had no black screen.

Has anyone else expereinced this?

I think the key points to this is:

Intel NUC7i3bnk

Windows 10 update 1803

logging into a domain

black screen on logout

Installed win 10 pro on my NUC, but after installation the OS does not load. The installation has created 2 OS bootloader partitions in UEFI, but I cannot boot on either of these partitions.

Hello,

I installed my NUC with Windows10 and it worked well.

Then I figure out that BIOS was version 22 from Feb 2018, which was very old (I bought a new product on Amazon 3 weeks ago).

So I tried to update it to current 49 version.

I put .BIO file on USB device, asked for update, seen some screen saying it was updating, seen some reboot,

after 1/2 hour I considered that it was done (no message at all)

But now, when switching on, it doesn't display anything on the screen (power LED is ON)

So I cannot use my NUC anymore, could anybody help ?

Any clue of what I could do ?

Thanks for any feedback

Configuration = NUC 8i7HNK / 1TB Samsung nVMe / 32GB Corsair RAM

Hi,

Shortly after a BIOS update that removed legacy boot, my ethernet adapters disappeared from the device tree. The driver install does not detect them, they do not show up as other device, and I do not get a link light when I plug a cable into either jack (which is connected elsewhere). They are enabled in the BIOS. I tried clearing the CMOS battery and also resetting the BIOS by removing the jumper. When I remove the jumper and boot, during the 'reset' I get activity lights back on the ports for a short moment, then the BIOS is reset and they turn off. Even while I am in the BIOS I do not get activity lights, and the ethernet adapters are clearly checked as on in the bios. Any ideas?

hii there..im not sure if my pc get update or not, but when i starting up the pc it is stuck on black screen..

someone help me..
