What are the USB cable length limitations for the Bloomberg keyboard 4 (Starboard)?

The USB specification limits the length of a cable between USB 2.0 devices to 5 meters (or about 16 feet). In order to go beyond these limits our clients will need to use self-powered USB hubs, self-powered USB active extension cables or self-powered USB over Ethernet products that meet the requirements as advised on Bloomberg keyboard 4 (Starboard).
