      How to I fix an unknown device error.  I have a Lenovo M91p with Windows 7x64 Pro.  I cannot figure how to solve the problem with PCI Simple Communications Controller showing with the yellow exclamation.  I've tried to update the drivers to no avail.  I get a Code 28 error that says the drivers on my computer are all current.
