No puedo identificar a que dispositivo corresponde este aviso Qué driver es necesario ?

Am using NUC5i3RYK in remote control application.

Have over 100 sites.

Last 10 days have had 3 units drop their ethernet connection.

These units then drop off the network and I have to go to site with keyboard mouse and monitor to correct.

Any thoughts

Rgds ancient 1914

I have

• a camera (IDS UI-3131LE) with a USB-C port and
• a NUC 7i7BNH with a USB-C port running Ubuntu 16.04 (kernel version 4.10.0-40).

Seems like a perfect match, but the camera is not being recognized when connected to the PC's USB-C port. It only gets power.

It seems the USB-C port does not work at all.

What I've tried so far:

• updated BIOS
• turned Thunderbolt both off and on in BIOS
• both disabled and enabled USB Legacy support in BIOS
• connected a phone to the USB-C port: it only charges
• confirmed that the two USB-C cables I am using work in another setup
• connected the camera to a regular USB port on the NUC (with a USB-C to regular USB cable): works.
  /var/log/kern.log says:

  Nothing shows up there when connecting to USB-C though. (same with sudo dmesg)

The only thing lspci -k states about USB is:

    00:14.0 USB controller: Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller (rev 21)

        Subsystem: Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller

        Kernel driver in use: xhci_hcd

I don't know if this includes drivers for USB-C.

How can I get my USB-C port working?

Hi

I am unable to play 4k files properly on a PC connected to a TV.

When I open a MKV file which is a 4K HEVC x265 I get no Video only audio. And when I forward the time, the audio plays fine, but the video shows a very choppy screen then the video is frozen and the audio continues.

I am not sure what the issue is.

Maybe I need to change settings, but I dont know what settings to change. (currently using default settings.)

Maybe my PC is not powerful enough to play this content at 4k? (but they advertise that they can do 2 screens at 4k just fine)

This forum really helped me out, so wanted to share my experience with CentOS7 install on a NUC7i5BNH using a USB Fob/key in case someone else can use it:

TL;DR: Switched from a junky USB 1.0 8GB fob to 'brand name' USB 3.0 32GB fob using same ISO CentOS7 image (installed with RUFUS), and it fixed my install problems and I was able to successfully run CentOS7 install from USB to my NUC (NUC7i5BNH).

Couple Key Points that really helped me:

1) I followed Intel instructions for updating my NUC BIOS using a USB fob.  Pretty easy and the tool def works letting you download the BIOS file locally, then using F7 at boot on the NUC, starting the BIOS update, and having it look for the BIOS update file you downloaded to the USB.

2) If you are creating your USB CentOS installer on a Windows machine, use RUFUS to make it.

2) This was my biggest hurdle....some people may swear this isn't possible...but this made mine work:  I tried repeatedly installing CentOS7 "minimum install" from a junky USB 1.0 stick I had made a month ago, and had SUCCESSFULLY used on a separate laptop CentOS7 install.  I had used this CentOS7 minimum install USB probably 6-7 times in the past month with no problems.  So...I used the same 8GB USB with the CentOS7 image already on there on my NUC. Installing on the NUC it would run the installer, but when it got to the GUI page of install where you choose your language, I would get random errors which would never let me continue the install.  Running a media check would result in "failed" but I was still able to use the USB to install on a test laptop, no problem.

So...for a more thorough test, I used RUFUS and overwrote the old beater 8GB USB with an UBUNTU install image I'd also used recently.  Using the same 8GB USB stick now imaged with an UBUNTU image using RUFUS I also get an error part way through the install (but it would start the install, just never would finish).

So...ultimately, for fun, I got a clean USB 3.0 32GB Fob, and installed the original CentOS7 ISO I already had, and after I did that, the install was flawless.

You can do checksum/tests to make sure your packages you downloaded are fine, and I did those sorts of things...so I'm pretty sure my old junky USB1.0 was somehow the problem on the NUC  (again, I used that USB on a crappy test laptop a lot recently and it worked fine instaalling CentOS7 minimum).   ...and moving to a decent USB that was USB3.0 seemed to fix everything.   Also (not that it matters) I tried this in front and rear ports of the NUC...and that had no effect (not that it would).

Happily humming along with CentOS7 on a NUC7i5BNH now.

Hope this helps someone avoid some wasted time.

The NUC not accept SSD

This BIOS

The SSD does not appear !

I make sure the SATA Cable is Good

And SSD In the right place

Where is the problem and what is the solution?

My setup is a NUC6i7KYK with 2x16Gb of DDR4 RAM and a V-NAND SSD 850 EVO M.2 from Samsung. I bought two identical 28" 4K UHD ASUS PB287Q monitors and was immediately disappointed I couldn't daisy chain them using the Display Port. My bad, didn't do my research, nothing to do with the NUC.

So I'm running two identical monitors; main monitor connected using the Mini DisplayPort, secondary connected with HDMI.

My issue: Every time the screens wake up from sleep all my open windows on the secondary monitor have moved to the primary one, and I have to re-arrange all my windows all over again.

What I expect to happen: On wake-up I want my monitors to persist my program windows the way I had them arranged before the monitors shut off.

* I'm running Windows 10 v1709 (OS build 16299.125)

* ASUS doesn't offer display drivers for these monitors, they use the Microsoft Generic PnP Monitor drivers.

* The Intel Iris Graphics Control Panel identifies the main (DPLink) monitor as a Digital Display, the second monitor (HDMI) as a Digital Television.

* BIOS/Firmware/drivers all up to date as per Intel Driver & Support Assistant 3.1.0.12

I'm very happy with the Skull Canyon (my first NUC) and I'd be the first to admit this is a minor issue. But it does get old and I hope that one of you guys can help me out. Fingers crossed!

m.

I installed Latest Intel Driver & Support Assistant Tool (v.3.0.0.9), it says there are 3 updates but when I start it, it launches Chrome browser and at Intel® Driver & Support Assistant page and I get an error message:

[Oops, something went wrong while trying to scan. Please try again, or see our FAQs for help.]

There is no error code, obviously the FAQ section does not contain any clue that might help.

with v2 of this tool, even if it did not detect properly all intel drivers on the system I could install and see driver versions for most of them, with v.3 I can not do anything.

I have Intel NUC6i5SYH and recently I have updated my Bluetooth driver to version 20 from that time forward my Bluetooth device became unrecognizable by my OS Windows 10 x64, I have opened a support request from Intel, but I want to see if anyone else experienced the same issue.

Hoping someone will give me some good idea how to solve issue I have with my new NUC7i7BNHXG, 32GB Optane plus 2TB HD.

So, after bios update to the newest version, windows 10 cannot load any more. I tried to recover with image that I made on external drive, but apparently I cannot recover this way cos there is no any account as administrator set it up. Then I tried windows reset, but it is stuck on 1%.

For me looks like there is something with Optane memory that is cosing this, but I am not sure what.

Settings in bios seems ok, as far I understand it.

Is there any way to recover my dearest NUC in working condition again?

Hi at all,

We need to use Windows 10 x86 on this NUC and i have found all driver but not the graphics driver, we missing only that.

So the question is simple, since only the video drivers are missing to run Windows x86 sooner or later they will come out? or will this model of the NUC always be locked to Windows 10 x64 ?

I'm trying to update my DC53427HYE to BIOS version 49 via the F7 procedure. The updater recognizes my USB drive and the RK0049.bio file on that drive but after confirmation the system immediately reboots instead of starting the update. After the reboot the BIOS Event Log shows the message "Flash Update Failed (21)". Does anyone know the meaning of this error 21?

Tengo un nuevo NUC7i3BNH con un disco CRUCIAL MX300 275GB SATA M2 con Win10 Pro. Le he querido instalar un segundo disco CRUCIAL MX300 2,5” SATA pero no lo reconocen ni aparece en la BIOS ni lo ve Windows. Pienso que he hecho algo mal, pero no como arreglarlo. ¿Alguna idea?

Hi, I have one of the above that I want to connect to a DVI monitor, I have used a HDMI - DVI adaptor & HDMI - DVI cable and neither output a display.

HDMI & DVI should be the same technology so I am very surprised that this doesnt work, any ideas?

In windows advance color it only does Ycbcr420 10 bit 4k 60p. I have a Samsung js8500 TV with UHD on. Up to date with all the latest updates for my nuc7i5bnk and windows with HDR.

We are experiencing a problem with NUC7i5BNH running with two 16GB SO-DIMMs. After updating the bios from the original 42 to 57 the unit powers up really slow from cold state. It takes about 45s-1min to reach the Intel NUC logo page and it takes several seconds until the "F2/F7/F10" texts appear. Normally all this happens in <10 seconds pressing the power button.

A post error message "(a7) me fw downgrade request mespilock failed" is briefly displayed before the boot process is started. Warm restarts seem normal (=fast) and the memories pass Memtest normally. The unit seems to operating normally besides the very slow cold boot and the post error message. We definitely cannot deliver the unit to a customer in this condition.

We have reproduced the problem with two NUC7i5BNH units. On the second unit we did everything in a very controlled manner. The unit worked perfectly with the 42 version; all problems appeared after the update to 57. I do realise that the problem might be some incompatibility with the Corsair memories but they work individually and also pass memtest together after the slow cold boot has finished. I really hesitate to spend ~400eur just try out a second set of memories.

Things done/tried:

• BIOS update with proper "Reset bios settings to defaults" after the update
• Tried bios recovery with jumper and power menu methods -> no effect
• Tried with memories individually in either slots -> worked fine without problems (fast, no post error)
• Tried different (Kingston, Adata) smaller memories individually in the unit -> worked fine without problems (fast, no post error)

Things not tried:

• Different 2 x 16GB modules. Unfortunately we do not have Kingston/AData 2133MHz 16GB modules available. We could get our hands on 2 x 16GB 2400MHz Adata. However the memories are really expensive to just try out. The Corsair modules themselves pass memtest and work individually in the same units. Also their specifications meet the requirements stated in the Technical Product Specification.
• Any smaller memories in dual channel configuration. We have a chance for this on Monday. However it does not really help us to find out that 2x4 or 2x8 works.
• Downgrading BIOS to anything earlier to 57 (see BIOS downgrade question below)

Components:

Intel NUC7i5BNH original BIOS 42 updated to 57

2 x Corsair CMSO16GX4M1A2133C15 (16GB, 2133MHz, 15-15-15-36)

No SSD installed at the moment (AData SX8000 will be installed once the memory problem is solved)

BIOS release notes state that you could downgrade from 57 -> 54: "Due to a security enhancement, it will not be possible to go to any BIOS earlier than BIOS 0054."

However the BIOS update readme states the following: "If you are trying to downgrade to a previous BIOS version and its Intel® ME Firmware version is older than that currently on the motherboard, then the downgrade is NOT supported."

The ME FW in 57 is newer than in 54 (11.8.50.3425 vs 11.6.27.3264). Is the downgrade to 54 allowed/supported or not?

Questions:

1. What is this post error message "(a7) me fw downgrade request mespilock failed"? We have definitely not downgraded anything. Is the unit internally trying to perform some kind of revert to previous bios when the post is taking too long? Could not find any google hits on NUC with this error.
2. Is the BIOS downgrade from 57 to any previous version allowed/supported? Since the documentation would indicate that we cannot downgrade (see above), we seem stuck with 57.
3. Has any of the relevant BIOS settings changed between 42 to 57? These do not seem to be listed in the release notes.
4. Are there any BIOS settings we could try to change? Eg. memory timings or the "Round trip latency optimisation".
5. Anything else we could try?

We provide Intel NUC solutions as a business and have installed several hundred units since 2013. This is the first time we experience this kind of problem. We have also provided NUC6 and NUC7 units with 32GB memory without problems but the NUC7i5BNH+Corsair 2x16GB combo is our first.

Any help is well appreciated!

I picked up a NUC6CAYH with the plan of using it for Libreelec.  I realize this is not a supported OS, but there are many others using the NUC6CAY for this without issue.

I have 2 x HyperX Impact 4GB 1866MHz DDR3L CL11 SODIMM 1.35V HX318LS11IB/4 installed. (tested with memtest for 48 hours without issue.)  I have used both a Samsung 830 SSD, and an ADATA SP600

I have consistent crashing and freezing with Libreelec, that others are not experiencing.  Sometimes it runs without crashing for an hour or so, sometimes only minutes.

I have experienced freezing in the visual bios, requiring a hard reset, at least a few times, and with both 0041, and 0042 bios.

I decided to install windows 10, as a test of an "approved" OS.  Windows Setup experienced a crash during install, and after install, the Win 10 install itself experienced a BSOD.  Additionally with Win 10, I am unable to install the LAN driver, no realtek lan is recognized... nothing is shown in the device manager either (no, it is NOT disabled in the bios)

I can gather info if it would help, but I am thinking there may be something wrong with my NUC.

What needs to be done to get a replacement?

I had Win 7 64 BIT Pro installed, I cloned that drive to my new M.2 Adata drive.

Told BIOS to boot to that drive. Works fine. Still not as fast as a 6 year old Acer REVO with M.2 drive.

Would like to know the Visual BIOS Settings to Fresh install WIN 10 on the M.2 drive.

BIOS and WIN 10 BOTH see the M.2 drive. My BIOS VER is RYBDWi35.86A.0367.2017.0929.1059.

Intel driver update says my drivers are current.

Intel says my drive is not been tested and approved. Any Help for my question?

Hi,

I have two NUC's DC3217IYE. I think that makes them 3rd Gen.

The issue I have is from time to time the NUC's do not see the internal drives on boot and start to try to boot from the Lan.

The drives are Msata 60gb Intel's. Both NUC's are mounted upside down under office desks.

The only way I can get the drive to be 'seen' again is by opening the NUC removing and re-inserting the drives.

Does anyone have any idea what could be going on, please?

I updated the bios to the latest version about a year ago. One of the NUC's I have just upgraded the mSata drive to a new 128gb crucial Msata drive but the same issue has occurred.

Thank you!
