Hi
I'm struggling trying to make a Sanguinololu board get detected under Windows 8.1. I installed the latest FTDI 2.10 WHQL Certified drivers. I got 2 Sanguinololu cards and one of them works flawlessly under Windows 8.1 with that driver but the other seems to have this problem: "Unknown USB Device (Device Descriptor Request Failed) - Error 43". I know for sure that the board works, because I tested in another PC with Windows 7! It's very rare!! I've been researching the internet for the past few days and tried almost everything but with no success... any ideas??
