PCI Simple Communications Controller Driver issue

[Strokecity1]

Hello all, I am trying to find a driver for PCI Simple Communications Controller Driver without much luck. I have tried many suggestions on various sites and installed many drivers to no avail. There are two entries listed under "Other Devices" in Device Manager with the same name. Can anyone help me with this?

Hi:

I don't see the driver you need for that device listed on the support page.

See if this one works:

Intel Management Engine Interface (MEI) Driver

Hello Paul,

Many thanks for this but unfortunatly it did not install. It failed with a wrong platform error message.

Hi:

Sorry that driver didn't work.

I happen to have a HP Stream Pro G4 with the Celeron N3450 quad core processor.

I just checked my notebook's device manager, and the driver I gave you is not the right driver.

My notebook does not have an Intel Management Engine Interface device, so that is why HP does not have that driver on the support page.

Please post the hardware ID for the PCI Simple Comms Controller needing the device, so I can figure out exactly which driver it needs.

Use this guide for how to find the hardware ID for a device...

I was wondering why this driver was not listed on the HP support site tbh.

Here is the info from my laptop. There are 2 "PCI Simple Communications Controller" entries listed under "Other Devices" section in Device Manager.

Here goes:

Other Devices:

--> General tab:

Hi:

I have searched high and low, and unfortunately, I cannot find the driver you need for that ID.

I checked the system devices category in my HP stream 11 Pro and cannot find any device that has that ID.

Everything seems to point to it being an Intel TXE device but mine has a different ID than that (5A9A)

If you do a general search on the internet of 'PCI\VEN_8086&DEV_5A9E,' no one seems to be able to find the driver for it.

If you want to try the updated Intel chipset driver, perhaps that may work.

If you ever figure it out, please let us know what driver was needed.

[Strokecity1]

Thanks for trying. I will let you know if I ever find it.

[Paul_Tikkanen]

You're very welcome.

Usually, I can find the most elusive drivers but that one has me stumped.

Sorry I wasn't able to help.

I assume you tried updating the driver via the device in the device manager?

Right click on the device, select Update driver, select the automatic update...

[Strokecity1]

Yes i think I have tried everything before joining this forum to ask for help.

There is one other last-ditch suggestion you can try.

If you look at this discussion, the person is indicating that those devices only show up if Windows is installed in Legacy mode.

PXE support in Latitude 3180/3189 - Dell Community

Did you install W10 in UEFI mode or Legacy mode?

If you installed W10 in Legacy mode, try installing it in UEFI mode by booting your USB installation flash drive from the EFI USB Diskette on Key/USB hard drive.

I installed W10 in my Stream in UEFI mode so I could enable Secure boot.

I upgraded my Stream 11 Pro G4 to Windows 11 Pro and it works great.
