I bought this cable to connect my PC to my laptop to transfer data. The cable is not recognized by my PC nor my laptop !! When I connect them nothing happens, nothing appears on the screen, an icon informing me that périf was plugged. NOTHING! I do not understand and am going to see if I can find on the internet solution, or try to connect other devices through this cable ... to be continued ... On the other hand I got this gray cable and not black as described on the website. I received it within 5 working day.
