Hi:

I am assuming you have installed W7?

If so, here are the drivers you need for the serial port and usb controllers...

This package provides the Intel Management Engine Components Driver for supported notebook models running a supported operating system.

This package contains the Intel USB 3.0 Driver for Intel 8 and U/Y Series Products for supported notebook models running a supported operating system.

One of the unknown devices probably needs this driver...

Receives notifications from the integrated accelerometer and automatically parks the hard drive to reduce the risk of damage if the PC is accidentally dropped.

The other unknown device probably needs this driver...

This package contains the driver that enables the Synaptics (Validity) Fingerprint Sensor in supported notebook models that are running a supported operating system. The fingerprint sensor scans fingerprints for use with biometric security applications.
