PCI simple communication controller problem on Dell N5040

Hello,

I recently bought Dell N5040 laptop with chipset Intel PCH HM57 and processor Intel Pentium P6200.After I have installed Windows7 and all drivers that were needed , I still need driver for PCI simple communication controller. Hardware Ids are: PCI\VEN_8086&DEV_3B64&SUBSYS_05051028&REV_06
That showed me that I am looking for driver  for HM55 Express Chipset LPC Interface Controller - 3B09. I have tryed all tools from Intel's site , but nothing helped. If you have an idea what to do, help me!
