The Asus Support Device driver refers to a general driver package that might be installed to support various Asus-specific hardware or software features on a laptop or desktop. This driver can include support for various components such as the Asus Smart Gesture (for touchpad controls), Asus Battery Health Charging, or other system utilities or technologies that are unique to Asus devices.

In some cases, the Asus Support Device driver can also help with ensuring your system is properly updated and functioning by supporting Asus-specific tools like the Asus Live Update, which keeps your system’s firmware and drivers up to date.
