Unsigned driver

[Jeff Barnett]

Got a new keyboard for one of our win 7 computers. It's a Logitech G213
Prodigy - touch is nice and there are a few media keys. Logitech claims
Win 7 compatibility. However, you must load their G Hub software (a
prior version that works with 8.1 also). Loading that software leads to
a diagnostic that the drivers are not M$ certified.

I vaguely remember being able to stifle that check but not how to do so.
Would one of you please remind me. [Windows 7 PRO SP1 64-bit] TIA.

Driver munging is addressed a bit here. A few breadcrumbs for further research.

But you're in quite a mess.

The signing on these appears valid, but these are for Win11 64 bit. One thing
to notice, is the signing certificates are only good for three years. The G213
has likely been around a few years more than that.

At the application level, there might be

LCC
LGS Logitech Gaming Software
G-HUB

as application software.

Maybe if you use archive.org and you take the web page claiming Win7 compatibility back
in time, you might find more software that way.

Trust me, the best Logitech products, are the ones that use standard Class drivers
and have zero applications needed to run them :-) The mouse I'm using is a Logitech,
and it needs... nothing. Just the standard OS provided support is enough.

I have two backlit keyboards here, an XPG and some $20 Chinese thing (when I went to
the store for a second XPG, there were none). And both of those have keyboard combo-keys
for control. No software. My third keyboard in the room, has rubber multimedia buttons,
("CD in box) and those started working around Windows 10 or so, on their own :-) spooky.

I've been burned before on the software side of hardware, and I'm ashamed to
report, I haven't learned my lesson and went back for more abuse. My Logitech 9000
webcam (very nice), stopped working properly when FrameServe came out for Windows 10.
It's stayed in the box, since. I do plug it into the Win7 setup, when I need to
do a Zoom-style conference with a doctor.

Thanks for the information. There is a "however" however: There are two
places on the Logitech site to download the software for this particular
keyboard. One place just offers choices of "Windows" vs. "Mac". The
other actually has a Windows 7 option. We are trying to install the latter.

I looked at the article you cited above and that led to a few
observations and questions: 1) Our machines tend to boot to fast to slip
an F8 into the boot sequence manually. 2) How does this apply to a USB
device with its peculiar ordering of loading and connecting? 3) Do you
need to apply the F8 razzle dazzle every time you reboot?

I hope you can help us get this sorted. TIA

PS Logitech "escalated" the issue since phone support was out of their
depth. I think they are motivated since their web site specifically that
this keyboard is Windows 7/8.1 compatible. I don't trust their process
in cases like this so I'm consulting you all here.

There are alternate ways to get to Safe Mode. If that's what you want.

Start : Run : msconfig has some Safe Mode options.

But my favourite method is for Vista+ OSes:

Administrator terminal

bcdedit /store C:\boot\BCD /set {bootmgr} displaybootmenu True # If repairing using
# Command Prompt from
# an installer DVD (and wanting F8 on next start)

bcdedit /set {bootmgr} displaybootmenu True # Can set this while OS running, using this format

What that does, is trade the trusty Tile boot buttons,
for old-fashioned WinXP era white-text-on-black-background.

In addition to listing the OSes in white text,
it also lists an F8 option. You have to look at the picture carefully,
to spot the F8. (The second link is a Tile example, as a contrast)

https://qph.cf2.quoracdn.net/main-qimg-a02fe9d0f0a400b95e33506cd90c2bbe

( Tile version: Loading Image... )

Since the boot menu then stays on the screen for an extended period,
you should have plenty of time to press F8. The timer is set to 30 seconds,
but you can change that if you are a Ninja.

To go back to the GUI style OS selection menu, it's something like:

Administrator terminal

bcdedit /deletevalue {bootmgr} displaybootmenu

( https://www.tenforums.com/tutorials/22455-enable-disable-f8-advanced-boot-options-windows-10-a-6.html )

You can review your BCD file, by just typing

bcdedit # Then look for the line with the "displaybootmenu" in it

bcdedit can do a good many other things. Many of the things
that work in W10 or W11, work in W7 too.

Until your suggestion and Paul's followups, I'd been unaware that that
check _could_ be bypassed - but I thought that when it came up, there
was a "proceed anyway" or similar button; I always felt at that point
"good, I'm dealing with a company who refuse to go through a costly and
mostly pointless approval process".

Though that may only apply to software installs, not driver ones.

(I know the ability to ignore was removed - not sure when, I think
certainly by Windows 10.)

The software from Logitech is not just "drivers"; it's many megs of user
interface to settings (and other stuff as well) too. There are no
options to ignore presented. For the record, installation is attempted
by an administrator.

Was there really no normal keyboard that just works without installing
anything that you could get?

Also it probably works just fine without the software.

Of course there are simple keyboards that will work without loading
drivers! I even have a few here.

This keyboard functions as a simple keyboard without loading software;
after all it needs to function via USB with the bios to boot computer.

The keyboard was bought specifically to use some "non-simple"
capabilities; in particular a few media keys and backlight controls.
This keyboard costs several times what a simple keyboard costs so there
surely had to be some justification to purchase it.

And, no, not all of its capabilities work fine without the software. I'm
curious what I specifically said in my original message or responses to
others that made you think I must be a total idiot? NOTE: This isn't a
question that is lightly asked in a USENET forum -- it's rather like
wearing a sign that says kick me but your message begs me to ask.

The Logitech G213 Prodigy RGB Gaming Keyboard was introduced Sept 2016,
and is close to eight years old.

The software is inspired nonsense.

It does not install from that file, it starts a download
of yet more junk.

It expects .NET 4.0 .

It installs.

But, when it got to

logi_core_temp.sys

that throws a wobbly, because the packager-turkey
forgot to re-sign that one before release.

I cannot promise anything, but try renaming the file
in C:\Program Files\LGHUB

logi_core_temp.sys ==> logi_core_temp.sys.bak

After the rename, run the main program again (icon on desktop).

There is likely to be more functions than the name implies
in that driver file, but what are you going to do ? It could
be a CoreInfo-type system file which gets Intel Core Temps
and displays them.

I did this in a VM, and the bloody program took over the
screen and had to be ushered using ctrl-alt-delete to get
the Task Bar to show. What a bunch of pinheads. It's a
good thing I took malware precautions with this pig, by using the
VM as a place for it to mess up.

It didn't even ask me to plug in the fucking keyboard.
it just showed a graphic. And no controls.

Thanks for the additional information. I will try all of this Tuesday to
see what shakes out. I hate to start tinkering with something that's
likely to be a mess and have commitments that will break span of
attention. I have company today and stuff tomorrow. Also, I have a
second of these keyboards coming for another Win 7 computer that will
arrive Tuesday; if things go well with one computer, I want to do the
other while procedure is fresh in my head.

BTW This model really feels to be well made and the lettering seems to
be molded-in so shouldn't fade. I ordered the second before realizing
that it needed software to do everything; I just knew that typing felt
nice. So I'm trying to salvage two purchases, not one.

Just installed my new (second) keyboard on my computer and all went
smoothly!. Grabbed the download from where you pointed me, installed,
and away I went. Must say the software is underwhelming. I did encounter
the unsigned driver drivel this time too. EXCEPT I got an option to
ignore the problem which I did.

When spouse returns will go back to computer where problem originally
appeared. The installing users, in both cases, were administrators. I'll
try to determine if there was an opt out option that was really really
buried or something else. Will try to uninstall software and start with
a different simple keyboard attached.

Once again, thanks for the help.
