I have a Dazzle 8-in-1 Hi-Speed USB 2.0 Reader attached to a Dell 600M. I just got a Sandisk Ultra II 1GB SD card. The reader and the card are benchmarked on many sites at 4MB/sec or higher. I'm pretty sure neither is malfunctioning. However, the 600M doesn't seem to recognize it as 2.0-- the fastest I can read/write is 1MB/sec, i.e. USB 1.1 speeds. Anyone have any suggestions?
