"unknown device" and the properties list the location on Intel 82801DBM LPC Interface Controller?
Answers:
If the unknown device is just listed as "unknown device" and the properties list the location on Intel 82801DBM LPC Interface Controller, the machine probably came with a TPM Security module installed and they need to install ProtectTools Security Manager and Embedded Security for ProtectTools to install the driver.
The LPC controller is a low power controller that looks after things like fan controllers etc that run off the pci bus.if you are having a problem download the latest drivers for that chipset either from the Intel site or here at :http://drivermagic.com/p/nph-download.ph...
