In order to display the contents of your Vivlio e-reader on a computer and make transfers in USB
mode, configure your e-reader as follows: in Settings > Maintenance, select USB Mode: Ask
Once your e-reader is set up, connect it when it is turned on to your computer with a USB cable and select PC link among the two choices displayed on your e-reader's screen. If you plug in your e-reader when it is off, it will not offer you the option of transferring files but instead will automatically start charging the battery.
If this does not work, test the connection on another computer or with another micro USB cable
(intended for file transfer and not just for charging).
