I had the same exact trouble with my Toshiba Qosmio F55-Q502. I tried everything to fix the issue including using Toshiba's upgrade guide for Windows 7. What happened with me is when I installed Windows 7 32bit I lot the Function (FN) keys. Now, with this download I finally have my functions back! It's odd but this Flash Cards driver
isn't on the U.S. Toshiba support page. So, Thank you very much for the information! I have been scratching my head for months on this one! Thanks!
