Just got mine a week ago and I must say this is one sweet reader. I discoverd that it seems to run a lot faster on my USB 2.0 card then the standard USB 1.1 port on my wifes PC. It doesn't mention if it is USB 2.0, just USB 1.1. Also it shows up automatically in XP as 2 Removeable Storage Devices (one for the SM, MM, SD, and Memory Stick, and another for the CF and IBM Micro Drive). Really speedy reader, I am rather happy with it.
