Review: I am always a bit concerned when buying couplers, especially USB. No problem with these devices, they work every time and get lots of use.
Review: I bought 3 packs of 5 pieces of this product and this is not working how I was thinking it should. I did many tests to be sure what was happening. First I connected an USB Flash Drive directly to the USB 3.0 to check the performance (Picture Test #1). After that, I connected an USB A to USB A cable to my computer in the plug #1 and the plug #2 to the keystone jack to create an extension to connect a device (my idea was to pass this to another room for the wall), this does not work how I was thinking with an external disk, but this work like USB 2.0 with the same USB Flash Drive, the speed was reduced from 240 MB/s to 40 MB/s read and from 59 MB/s to 29 MB/s write. After some days I could undertstand what the problem was. I used an USB A to A and usually these are crossed. I mean, the pin #5 in the plug #1 is connected to pin #8 in the plug #2, pin #6 to pin #7, pin #8 to pin #5 and pin #9 to pin #6 (Picture Table 1). Therefore, if we use this type of cable and this keystone jack to create an extension, the result will be something crossed and will not work to connect USB 3.0 devices, only will work with USB 2.0, because the pins used to USB 2.0 are not crossed (Pin 1 to Pin 4). To have this working we should use an special USB A to USB A cable with VBUS and Data Pair Straight Through (Picture Table 3). In my case I could not find this type of cable here in desertcart, so I had to change the connections directly on the connector. You can see a picture how I crossed the pins to get a direct cable connection. Also, other option is cut the cable and create a direct cable, I think this last it's better for the performance, we can weld the wires and conver these again with aluminum to avoid interferences. After this changes I tested and I can say this work like USB 3.0 (440 MB/s read and 449 MB/s write). I tested with an external M.2 Disk. Would be nice to have this jackstone key crossed to avoid an extra work, however, I could not find a keystone USB A female to USB A female crossed.
