Review on 🔌 Monoprice 113749 Select Series USB 3.0 A to A Female Extension Cable 1.5ft for PlayStation, Xbox, Oculus VR, USB Flash Drive, Card Reader, Hard Drive, Keyboard, Printer, Camera and More! by Jimmy Hargrove

Bought 2 and spliced them together to make it 12ft instead of 6ft and it only works if you use it alone as a 6ft cable and not if you link them together to increase its length to 12 feet. I have a 10-port USB hub and my external hard drives don't show up when connected. However when used individually it shows all 6 of my external hard drives but when combined it only shows 2 of them which defeats the purpose. So I'm sending them back.
