Cable Length Recommendations

USB Length 

For reliable operation of digital audio and MIDI you need to be careful not to use very long USB cables. The USB specification recommends the following lengths:

USB 1 devices have a maximum cable length of 3 meters (about 9 feet and 10 inches) and the maximum total length of all the USB cables connected to your computer should not exceed 18 meters (about 59 feet). iConnectivity mio and MIDI+ devices use USB 1.

USB 2 devices have a maximum cable length of 5 meters (or about 16 feet and 5 inches). iConnectivity AUDIO devices use USB 2.

USB 3 devices have a maximum cable length of 3 meters (about 9 feet and 10 inches), though this is highly dependent on cable quality. No current iConnectivity devices require USB 3.
