Needed to move a printer to the other end of the office and this cable made it possible. Was initially concerned the cable length would be a problem, however the use of the additional power source feeding the USB chip-set ensures that in actuality there has been no change in performance compared to when the printer sat alongside the print server.

Works well. Solved a problem to connect and power a USB device that wouldn't work over a standard USB extension cable.

Used to place a Zwave controller closer to other devices. Running off a RPI, just used two USB outlets on the RPI.

Has resolved a problem I previously had with USB items that stopped working intermittently due to insufficient power over a long cable. My only wish is that the length of cable from the active connection was a little longer
