Oh-No! More NUC

The Logitech Unifying USB module (dongle) may be the culprit in my NUC freeze up problems. I have moved the tiny module away from the computer and the through-the-case USB ports using a USB extension cable. I have done this with both of my NUC computers.

I do not know the actual cause of issues within the Logitech module. Internet speculations suggest it may be some harmonic problem with the new higher speed USB3 ports now in common use on most all PC’s. Logitech Unifying Transceivers were designed when USB2 was standard.  But this suggestion is speculation.

What happens and is most important, is if moving the modules away from the computer, the freezes stop. Putting the USB module out on an extension cable has always been a recommendation from Logitech if there are mouse and/or keyboard communication issues with the dongle.

For some folks simply using a different USB port fixes the problem without the extension.

The NUC is a very small and compact computer. All internal components are very close to each other. There is a large variety of radio frequency signals concentrated within and around that tiny package. As a 50 year plus experienced amateur radio builder and operator, I am amazed by how well all these computer radio frequencies co-exist with each other.

What has been difficult for me is determining if it is a mouse/keyboard issue. It acts and looks like a lot of other problems. I could go back to using a wired mouse and keyboard. If the problem ceases, the high probability it is the wireless connection.

Most long-time users know the Logitech wireless systems have been reliable. They are not on the top of the list of “usual suspects”. Maybe it’s time to move them higher in the list. I have to ponder, “Can it really be that simple to fix?”

UPDATE: 12/27/2020

I didn’t want to write another post on this subject. I will update this one.

I think the “smoking gun” has been discovered in the hands of WIN10 OS and therefor Microsoft. I find it strange Logitech is not aware. The picture makes it very obvious.

The logitech USB Unifying Receiver is a crucial link for their wireless (not Bluetooth) mice and keyboards to communicate to the personal computer. IT SHOULD NEVER BE TURNED OFF!

Apparently WIN10 does not know what the device does. Note the DEFAULT power management setting in the picture…

Logitech USB Input Device

<Check-Mark> Allow the computer to turn off this device to save power.

This is almost beyond belief. Turning this receiver off exactly matches the freeze-up conditions observed.

I have removed the check-mark. After a suitable time I will report if the computer freeze problem has been resolved.



NUC, NUC… Who’s There?

Yeah, another post about my NUC10.

I discovered a new system software update for my Intel NUC10. I occasionally wander to the Intel website and do a systems upgrade check.

The Intel NUC has a website:  It will test the NUC real time and advise and provide proper updates for the machine that is asking. Very cool, IMHO.

I have posted the paragraph above in a previous article.

My NUC10 has continued doing its lockup (seizure) tricks. It was well behaved for a couple of weeks and I thought the issue was resolved. Wrong. It continued but far less often. But any system lockup is unacceptable.

When I saw the new systems software, I had hope that perhaps Intel was providing a solution.

The update was a MAJOR one. It required about a half hour to self-install with several self-starting reboots. I am saying it acted like a major overhaul. Not a simple tweaking of values.

The very first thing I have noticed is the Hard Drive activity light on the front of the NUC is now operating! It never functioned since day one. Just steady on. Now it is absolutely indicating Hard Disk activity, flashing and flickering. Very nice.

I have hope other system fixes have taken place.

Too soon to be sure. I will certainly post again if the OS seizures continue.

Some Space in the Attic

The BLOG for “The Hobbyist Machine Shop” has lived with it own private URL ( since conception. It always was a bit extravagant for it to have a private domain. I was young and reckless in those days and new domain registrations were cheap.

Now retired, I look for more conservative ways to do things. A blog for “The hobbyist Machine Store” should live in a sub-domain of “The Hobbyist Machine Store”. It does not need to have it own domain and I don’t need to pay the rent for that private domain. What have I been thinking?  Ha!

A dozen mouse […] Continue reading » Some Space in the Attic

Can’t Stand the Heat?

The Intel NUC has been having “fainting” spells. Lots of write up about the problem in the Intel NUC forums and elsewhere on the internet. No one has the cause so therefore no solution. It is a random but re-occurring act.

I thought it might be the new embedded Linux feature. I disabled that feature but it has not proven to have been a contributing cause.

Just about every component and accessory has been questioned. Most users experiencing this action think it is some sort of driver software problem. It is certainly tied to the video in some fashion.

I think it acts like a thermal problem. That would […] Continue reading » Can’t Stand the Heat?

Seizure Research

I thought researching something as mundane as what type of anti-seize compound would be proper for my 3D printer nozzle would be an easy task. What I found was a few standard ingredients for a variety of applications. But then a very poor (meaning non-specific) explanation of how, when, where each “blend” of materials should be selected.

What this indicates is not many makers of the anti-seize material have taken the time and effort to publish (on the internet) a substantial product selection guide. It may exist but it is just been difficult for me to discover with a  key word search.

Suffice to say, I did find enough […] Continue reading » Seizure Research
