The USB standard specifies the maximum cable length for different USB versions are as follows:

  • USB 1.0 & 1.1: The maximum cable length is 5 meters (16 feet, 5 inches).
  • USB 2.0: The maximum cable length is also 5 meters (16 feet, 5 inches).
  • USB 3.0 and later: The maximum cable length is 3 meters (9 feet, 10 inches), but this can also be extended up to 30 meters using active extension cables or USB hubs.


    Hubs and extenders are not supported for use with Q-SYS hardware.

  • The maximum cable length is 6 feet (~2 meters).


    It is important to understand that longer cable lengths can result in signal degradation and slower data transfer rates, particularly for USB 3.0 and later versions. To minimize these issues, it is recommended to use high-quality cables that meet the USB standard specifications and to avoid chaining multiple extension cables together, as this can increase the risk of signal loss and reduce the overall performance of the USB connection.
