We ran into an issue when installing the Drivers for the USB 2.0 UGA from ZettaGuard. The small disc could not be read on the computer we were installing it on. We tried to download it from the ZettGuard website but it would load with an error message.
Googled USB 2.0 UGA and found a driver on Plugable.com. Downloaded and installed the driver, the monitor connected and worked great. We added the link related to the driver location below.
