extension distance will depend on cable quality, the use of USB hubs, and
interference from other devices nearby.
Using a USB hub on the output of the EXT-USB2.0-SR would reduce the extension
range to approximately 40 meters/132 feet. The exact range reduction would
depend on the USB hub design. Some hubs may perform better than others.
