The C5210 is equipped with 5 USB connectors — 2 on the front panel and 3 on the back panel. However, the controller is capable of supporting only one USB device at a time, regardless of what USB connector the device is connected to. If you connect a second USB device while the first is already connected, the system will return an error.
