Lenovo T500 bluetooth and other base system devices not working after upgrading to Windows 8



I have a Lenovo T500, which came preinstalled with Windows Vista Business. All the hardware components were working perfectly.


I took advantage of the Windows 8 upgrade offer from Microsoft and performed an installation.


Windows 8 automatically installed most drivers by itself, but there are three entries in the device manager that are not working:

The hardware IDs for the devices that are missing are as follows:


First Base System Device:


Second Base System Device:


PCI Simple Communications Controller:

PCI\VEN_8086&DEV_2A44&CC_0780 only has support up to Windows 7.


Please let me know how to identify what these devices are and also, where do I find drivers?


Thank you.

Good day.


While I have no information about availability of Windows 8 drivers, searching at: yields the data below on your three problematic devices. There are some reports of Windows 7 drivers working in Windows 8, but I can't confirm personally.


Device Id  Chip Description                   Vendor Id  Vendor Name
0x0592     Rioh Memory Stick Controller       0x1180     Ricoh
0x0843     Ricoh SD/Host Controller           0x1180     Ricoh
0x2A44     Intel Management Engine Interface  0x8086     Intel Corporation


Hopefully, this info will help a bit.

Did you get a resolution on this? I've got the same problem with those three devices showing up as unknown with Windows 8...
