Installing GV-Hub Drivers
When you connect GV-Hub to the computer, the Found New Hardware Wizard will
automatically detect the device. Once the wizard is open, follow these steps to install
the hub drivers.
1. Insert the installation CD to your computer.
2. Select Install the software automatically, and then click Next.
3. When this warning window appears, click Continue Anyway.
4. When the installation is completed, click Finish.

the driver.

Ports field, you should see the 4 entries for Prolific USB-to Serial Bridge.
