This cable is intended to enable a USB HDD (USB 3.0) with external power supply with a SmartTV connect (USB 2.0). This, however, was not working. An experiment with a 2nd hard drive and a USB flash drive led to the same result. Subsequent tests on the PC, including with other peripherals mastered the cable perfectly. So if you want to implement the above projects should to the also offered under AmazonBasics USB 2.0 cable access, which was to produce the desired compound able. For most other applications however the cable appears to be suitable. It is also positive to note that both plug and socket for very good and tight worry so loose contacts or even a drop in the connected line are not expected. All in all a very good extension cord, with few restrictions.
