An unknown device is detected in all the computers/laptops we buy from a specific vendor. The vendor himself does not have any idea of what this device could be.

The vendor and I searched the hardware physically for something unknown to us, but found nothing. Any help in identifying what this device could be?

Device Type: Other devices
Manufacturer: Unknown
Location: on Intel(R) 82801FBM LPC Interface Controller - 2641

Note: Disabling and enabling this device does not make a difference.

Is it a TPM?

In devmgmt.msc you should be able to find out what resources (I/O ports, memory addresses, IRQs) it's taking up. Based on those you may be able to find out what device it is. I don't think LPC has vendor/device ID strings like the PCI bus...

so kindly guide on how to know what device this is? –  Doopy Doo Jun 2 '12 at 20:29

Shamelessly referring to my own post on identifying a graphics card:

Use the same method to get the PCI ID of the LPC controller rather than the graphics card in the example below.

enter image description here

Fill in the PCI ID in this database or in a similar one.

Then hopefully find the driver for your LPC controller
