Samsung SPH-M610

So I have the M610 and I got one of the sprint stores to give me a usb data cable that they had left over but they didn't have a disc for it and I was wondering if there was a way off the internet to download the drivers or downloads so that it makes it able for me to access my memory card without having to turn off my phone and pulling out my battery if anyone can answer that that would be great. Please get back to me as soon as possible thanks.
