Windows7, and norton's diagnostic reports are reporting a bad driver on my T500. Here's what it says: Device Type: MpKsl8de752de Device Status: Device is not present, nor working properly, or does not have all of its drivers installed. Plug and Play ID: ROOT\LEGACY_MpKsl8de752de When I go to drivers in the control panel, everything looks good. Anyone ever see this?
Found it myself. MPKS files are associated with MSSE and these bad drivers are a remnant of an uninstall. I deleted them in "non-plug-and-play drivers".
