Connecting USB Devices
Your VAIO® computer may automatically restart or perform unexpectedly when USB devices are connected.
Sony Digital Cameras and Camcorders
When a Sony Digital Camera or Camcorder is connected to a VAIO computer via a USB port featuring USB Specification version 1.1 or some variations of USB 2.0, the computer may restart or behave unexpectedly.
USB Input Devices
The computer may automatically restart if a Universal Serial Bus (USB) input device, such as a USB mouse, is attached to a computer during a streaming USB audio or video session. This issue occurs if the USB bandwidth usage exceeds 100% when the USB device is connected. To avoid this issue, Sony recommends that you connect any USB input devices before beginning your audio or video streaming activities.
NOTICE!! A USB software update is now available for certain VAIO® computers. Please refer to the installation text for the applicable model listing.
