I take it that your computer has a memory card reader, correct? Try going to the manufacturer's support site and downloading the memory card reader driver for your specific model.
I did that and its not there and the one that its there its not compatible with my model and window, I choose the Window 7 and all that stuff but it doesnt let me I dont know why . Same thing with the webcam, it say its for Window 7 and when Installed it says Windows Vista Only. I found the webcam driver com driver.com but the memory stick reader its like impossible to find :S . But thanks anyway
