Unknown PCI Simple Communication Controller

I have a acer 4745g laptop installed with windows seven, however there is one driver missing with a yellow question mark on the device manager, PCI Simple Communications Controller. According to unknown device identifier it shows the chip as, intel 5 series/3400 series chipset family HECI controller. The device ID is as follows, PCI\VEN_8086&DEV_3B64&SUBSYS_03571025&REV_06. Where can I get this driver?

That's usually referring to the HECI drivers, or Intel Management Engine. I was able to find a bunch of links to the drivers by googling it, but here's a forum post with a link to them on Dell's site. Usually, Intel drivers work on any Intel board, regardless of whoever the OEM is.

thanks for the replies... may I ask what is the importance of the PCI Simple Communication
Controller? As it is right now I don't see anything wrong with my laptop...? Does enabling it really makes a difference?

@theog - thanks for the link but acer doesn't have the driver, the files on the website are the same as the ones that came with acer support DVD...

This driver seems to enhance hardware monitoring in some way, but am not sure. Take a look here.

The driver is available on the Intel support site but you'll have to look around for your particular mobo/chipset.
