Solved Two unknown drivers are in Device Manager

[quicqsolution]

Machine is an HP Compaq dc7800p Convertible Minitower
Serial Number: CZC8473P94
Product Number: FU291ES
Windows 7 -64bits


In device manager under "Other Deives" there is a yellow ? mark by "PCI Serial port" and PCI simple Communications Controller

The Details tab of PCI Serial Port" reveals that its Device Instance ID is:

Chip: Intel Q35 chipset Serial KT Controller

and the other PCI simple Communications Controller drivers name "Chip: Intel Q35 Chipset HECI Controller"


I cannot find these drivers , and I've installed and/or updated all the ones that I think might apply.

Here are these two drivers.


"Chip: Intel Q35 chipset Serial KT Controller"
"Chip: Intel Q35 Chipset HECI Controller"
I tried to download from HP website but I didn't find.
Does anyone know what the correct drivers are?

It seems a member had a similar problem before and found a solution from the Intel website.

See if that helps you too.

Please explain are they not in your Downloads .. Or can you just not run the Driver ?

I downloaded them and installed but after reboot the issue has not been solved.

Hi quicqsolution,

From the HP support site:

PCI Simple Communications Controller driver for HP... - HP Enterprise Business Community

Option 1: Download and install "sp38609.exe" from the post marked as solution.
Option 2: If running the .exe still does not work, try a forced/manual installation of the driver.

Sounds like an error message from the installer. Can you see the individual driver files, or they all packaged together? If you can extract them, then you force the driver to upgrade through Device Manager and point it to the right file path.

Just a thought,

Hi quicqsolution.

Does it cause any lack of functionality? If not, you should not be worried for it. Here is my device manager....



So as per it, there may be some issue with the connectivity of the phone, but it is nicely connected. See.



If it cause a real issue, get the latest Intel Management Engine driver for your system and install it.

I dont have Management Engine installed (personal thoughts only). If it is installed, the Device Manager does not show yellow triangles on the phone.

thanks for your post but this is not compatible with my machine.

That's quite odd. If your system is "HP Compaq dc7800 Convertible Minitower PC", it should work.

Would you kindly post a DxDiag for us?

1) Windows + R
2) Type "dxdiag".
3) Click Save All Information...
4) Save DxDiag.txt.
5) Attach or post the text file (using

 tags).

Sorry I was away before I saw your DxDiag, but glad you had your problem sorted. It would be also nice if you posted the solution/s you took, so members can reference this thread should they come across similar problems.
