USB Test

A USB (Universal Serial Bus) is an interface between a computer and a peripheral device such as a joystick, keyboard, or audio player. The "USB Test" checks the USB port and USB devices on your VAIO PC to make sure that the port and devices are working properly. Before starting the test, you need to disconnect the USB device from the USB port you want to check.

To start the "USB Test", click the [Run Test] button.
To abort testing, click the [Stop] button in the test progress window.
Once the test is complete, a summary of the test results will be displayed.
If you want to test another USB port, click the [Back] button to return to the top menu and click the [Run Test] button.
