How can I make the computer and Vimba Viewer recognize the camera?
1.
Check if the hardware supports your USB camera.
Is the power supply sufficient to operate the camera? See Power consumption
issues on page 228.

2.
Check if your computer has an appropriate USB 3.0 or 3.1 Gen 1 host controller
driver installed.
Windows 8 and later OS provide a USB 3.0 or 3.1 Gen 1 host controller driver. On
a properly installed OS, no problems should occur.
Windows 7 and earlier OS do not provide a USB 3.0 or 3.1 Gen 1 host controller
driver.
To install the host controller card:
Download the manufacturer USB 3.0 or 3.1 Gen 1 host controller driver.
Install the driver on your computer.
Result: The installed driver enables the host controller.

The camera, connected to a USB 3.0 or 3.1 Gen 1 hub, is not recognized anymore.
