Incredibly, I connected the cable 5 meters to a NAS usb3 and have connected to a sports usb3 my pc: where it worked perfectly with the usb3 cable supplied with the NAS, but much shorter ( 1 m), it is not working properly, the NAS is not recognized by the PC. By cons, when I plug this 5m cable on a USB2 input, it works! I checked the ports usb3 my pc, they work perfectly. Either I have received a defective cable, or the cable is not suitable in this length usb3. why I put him only two stars.
