    Lenovo ThinkCentre M90P : unknown devices

    redcell

      I recently downgraded a Lenovo Thinkcentre M90P from Windows 7 to Windows XP Pro, I've Installed from a my Win XP CD no branded (an original CD with no brand drivers included).

      The Machine's chipset is: Intel 5 Series/3400 Series

       

      Now from Device manager I've found 2 unknown devices, or better 2 devices without drivers:

       

      PCI Simple Communications Driver

      PCI Serial Port Driver

       

      I've downloaded from Lenovo's site all drivers for this machine but it seems there aren't drivers for these 2 above.

      I' ve read in another forum that for a Lenovo M57 or M58 the same problem was solved installing Intel AMT, but for this machine/motherboard I havent found this kind of drivers.

      What kind of device could be? Is there someone that had the same problem and has solved it?
