It may take about 15 seconds (or more) after the USB cable is connected for the VariOS to be detected.
• Is the USB cable connected correctly?
Make sure that the VariOS and your computer are correctly connected via a USB cable.
• Is USB enabled on your computer?
Refer to the operation manual for your computer, and make sure that USB is enabled.
• Does your computer meet the USB specifications?
If you are using a computer that does not fulfill the electrical requirements of the USB specifications,
operation may be unstable. In this case, you may be able to solve the problem by connecting a USB
hub.
If the above actions do not solve the problem, it is possible that the VariOS has been incorrectly
detected by the computer.
As described in <Deleting incorrect device information> (p. 143), delete the incorrect device
information, then re-install the driver. ( "Installing the Driver" (p. 22))
Q. "Found unknown device" appears even though you installed the driver
If your computer or USB hub has two or more USB connectors, and you connect the VariOS to a USB
connector to which the VariOS has never been connected before, the "Unknown device" dialog box
may appear even on a computer onto which you have already installed the driver.
Refer to "Installing the Driver" (p. 22), and install the driver once again. This is not a malfunction.
If the "Found unknown device" dialog box appears even though the VariOS is connected to the same
USB connector as before, it is possible that the computer has detected the VariOS incorrectly. As
described in <Deleting incorrect device information> (p. 143), delete the incorrect device
information, then re-install the driver. ( "Installing the Driver" (p. 22))
