There is one unknown device in the Other devices section, but from the driver details (ACPI SMO8800 1) it appears to be the Dell Freefall sensor. The Drive is a TSSTcorp DVD+-RW TS-U633F D500. Dell say they don't support Win 10 on this machine, and don't seem to want to provide a driver for it on the model specific page. After way too much time playing around, I finally found a software driver package I was happy with enough to call it good and that was the Windows 7 x64 Input drivers for the Latitude E6410 which will work just fine on the Dell Latitude E6400.
The Dell Latitude E6420 laptop is a common laptop used by corporate customers. The device is a few years old now and lacks support for Windows 10. Below are the drivers for Windows 10.
