Based on the reports and test results, I had bought the "Transcend JetFlash 760 16GB Memory Stick USB 3.0" for my Toshiba TV as brisk recording medium. This has always worked well, until it was no longer detected after about 5 months. Also at several ports on the PC (USB 2.0) was nothing to be done: only a brief flash on the stick and that's it - no more recognition or emotion. Luckily I bought the stick on Amazon, so the return went smoothly.
