My computer has integrated SD card reader that hadn't worked, then worked fine for a while after loading some updated drivers. Now has stopped working again (I hadn't messed around with anything either which is usually the reason these things happen). Have spent hours reading through posts with similar issues and loading different drivers (Windows 7, VISTA, XP, other companies, etc, etc.) The best I can get is the notification tone when inserting or removing a card, but no drive shows up! I am beginning to think that maybe not a driver problem?? Is there something else that needs to happen for the computer to see the drive? Looking through the threads on this forum it appears as if there are some pretty smart and knowledgeable people out there...can anyone offer advice? The computer is a Fujitsu notebook/tablet running Win 7 32-bit professional. The reader is an O2Micro device. Thanks in advance.
