I'll try to explain this more clearly.
I am using a Super Joy Box 11, which allows you to connect 4 XBox controllers to a single USB Hub, and then use the 4 controllers on your computer. Here is the Super Joy Box 11 device...

It is my understanding that I can also transfer files to the memory card from the computer when I have the card inserted into a controller that is connected to my computer via this device. However, when I tried to do this using Action Replay, it didn't recognize my memory card. It could not get the drivers for the memory card for some reason. This is to say, the Super Joy Box 11 worked fine without a memory card inserted. I was able to download the drivers for it from the manufacturers website. However, once I inserted an XBox memory card, I got the "searching for drivers" message once again, and after a few minutes the search game up empty. I then started this thread, and was told to try XPlorer360 beta 6 because "it doesn't need drivers". But I seem to have the same problem with XPlorer 360, as I get this message.....

I'm sure I am doing something stupid, but for the life of me, I can't figure out what.
