Problems and Solutions

USB Problems

USB device does not work

If the device requires external power, be sure that it is plugged securely into an electrical outlet as well as into a USB connector on the notebook.

Verify that the device is functioning properly by connecting it to a USB connector on another system.

Verify with the device manufacturer that you are using the correct driver(s).

Use the Device Manager utility in your operating system to check for and resolve any resource conflicts.

USB device does not work during startup

Refer to your model-specific documentation for information about USB legacy support. (USB legacy support enables a USB device, such as an optional external keyboard or mouse, to function during startup, before Windows loads.)
