PCI Simple Communication Controller - Windows 7 32-bit Enterprise level

I just installed a new image on an HP 8100 Elite CMT. I am working on trying to clear a PCI Simple Communication Controller. When I updated the driver, it then turned into "unknown device." When I try to update the driver on it, it tells me that the best driver for the device "Intel(R) Management Engine Interface" is already installed. Please help!

Hi Paul,

 

Thank you for such a prompt response!

 

I downloaded the driver from the link and ran it. Unfortunately I received an error message indicating that "The update did not complete successfully. (259)"...what should I do next?

You're very welcome.

 

I was hoping if that was the only driver you needed, that one would work.

 

So, plan B would be to install the driver which installs both that device and the PCI Serial Port from your PC's support and driver page.

Thanks Paul. I tried running that as well and got "an error occurred while registering one or more components. Set up will exit."

Hi:

 

That device is being very stubborn!

 

OK...time to manually install the driver.

 

Run the last file I posted again if you deleted the driver folder from the SWSetup folder.

 

Go to the device manager and click on the PCI Simple Comms Controller needing the driver.

 

Click on the driver tab.  Click on Update Driver.

 

Select the Browse my computer for driver software option and then at the bottom of that window, select the Let me pick from a list of device drivers on my computer.

 

Select Have Disk and browse to:  C:\SWSetup\sp56816\Drivers\MEI\HECI, and select the Intel(R) Management Engine Interface device from the list and see if the driver installs that way.

I tried to install it manually as you suggested. I get a popup saying that "The best driver software for your device is already installed. Windows has determined that the driver software for your device is up to date. Intel(R) Management Engine Interface."

 

The device in Device Manager still displays as "Unknown device."

Hi:

 

Sorry that nothing seems to be working.

 

Try uninstalling all drivers from that unknown device and then try installing the last driver I posted again.

 

That is definitely the driver needed.  As you can see from the contents of the setup information file, the hardware ID for that device is supported by the driver.

I uninstalled the driver for the device and rebooted the PC.

 

After reinstalling the driver, I got the a popup indicating that

 

"Windows encountered a problem installing the driver software for your device ... Intel(R) Management Engine Inteface ... The name is already in use as either a service name or a service display name."

 

Device Manager displays "unknown device."
