Review on SuperSpeed USB 3.0 20ft Extension Cable by Ruaeoda - Compatible with Printer, Xbox, Flash Drive, Card Reader, and More by Amy Moultrie

Since I'm the only one with this problem so far, I thought I should share it. I will be returning this cable as it doesn't work as I thought it would. . Maybe I have a defect, but I'm not sure. I plug it directly into a USB port on my computer and before I plug anything in, I get an error message saying it's unknown so it won't work. I've also tried plugging the device into an extension cord anyway but it still doesn't work and says check the cord. They gave me from the computer. I still give it 4* because it looks like a good cable if only it works. Maybe it's too long, but I'm not sure.
