The drivers are not installed properly. Refer to the "Quick Setup Guide".
Notes:
• Only USB 3.0 hubs are recommended for use with the IFC-EC2U3/UC. Hubs must support
USB 3.0 to perform at 5Gbps speeds. Non-compliant hubs will throttle all USB traffic to USB 2.0
or 1.1 speeds.
• For best results, USB hubs should be self-powered, or all USB devices connected to them must
include their own power supplies.
• Some USB devices do not support USB hubs. These devices will have to be plugged directly to
a USB port on the computer to function.
