There are several ways to distinguish USB 2.0 from USB 3.0. First, the “Super Speed” or SS logo may be present, indicating
a port is USB3.0. Usually, USB 2.0 ports are gray or black, while USB 3.0 ports are blue; however, this is not a steadfast rule.
Additionally, USB 3.0 ports have 9 wires while USB 2.0 ports only contain 4 wires. If you cannot tell a port’s USB version by the
color of the port, take a closer look at the number of wires inside the USB port. On a USB 3.0 port, you will see an additional
5 recessed signal wires inside the port, opposite the standard 4 wires.
Additionally, in Device Manager, a USB 3.0 port might have “USB3” in its name (e.g. Intel USB 3.0 eXtensible Host Controller).
You should ensure that the camera is connected to a USB 3.0 Root Hub. Determining which USB root hub your camera is
connected to is discussed below.
Each USB host controller has a Root Hub to which multiple physical ports are connected. Each port can have a device plugged
in or another hub to allow connection of more devices. However, the MicroPublisher 6 camera should be the only device
connected to a single USB Root Hub. If other devices are connected to the same Root Hub, then camera communication
may fail, which can result in camera hanging or image tearing depending on the bandwidth consumed by the other devices.
Since it is not always straightforward to tell which port on a PC is connected to which Root Hub, follow the procedure below
to make sure that the camera is the only device connected to its particular Root Hub.
1.
Open Device Manager (click the Start Button and type “Device
Manager”)
2.
In the menu, click View -> Devices by Connection (Figure 1)
3.
According to Figure 2, find the USB host controllers, expand them, and
check whether your camera is the only device connected to the Root
Hub.
