I installed Windows 7 on a Lenovo T400 laptop. In the Device Manager, the only piece of unrecognized hardware is a "PCI Simple Communications Controller". Does anybody know what driver I need for this?

I also just realized I have the same problem on my T400 running Windows 7 x64, luckily I found a solution. Looks like those devices are related to the Intel Advanced Management Technology in the BIOS.

The driver can be found on the IBM support website.

Here is a link to a blog that has a bit of an explanation.

And just for some additional info, here is the entire driver listing for the T400

Confirmed. The unknown "PCI Simple Communications Controller" ended up being the "Management Engine Interface" driver downloadable from the Lenovo site –  user45264 Aug 5 '10 at 16:22

a "PCI Simple Communications Controller" is usually an analog 56k modem.
