Well, my PC has one of those 50 billion in one card readers in it, so I use that, but the one that came with my R4 is the black semi-transparent one with the 2 pyramids on it and a white frosty transparent cap. Over the pyramids, it says USB 2.0 TransFlash. When I did try to use it, it worked.
How is that one working for most people? Is it good or crap?
Like I said, I use the onboard card reader on the PC, so I don't know if the one that came with my R4 is one of the ones that will short out or what.
EDIT: Never mind, bobrules answered it as I was posting.
