When connecting the host or peripherals, use only cable designed for USB signals.
Avoid or limit the use of adapters.
the USB Extender works as described in point-to-point applications. Do not use
additional adapters, patch panels, or couplers with the host USB cables, hub USB cables,
or twisted pair cables. Additional links in the signal chain can result in the reduction of
signal integrity and overall cable length performance.
