I see this error when a machine was either upgraded to 7 or is a fresh install. The usual fix is to find and install the machine's motherboard drivers.

I'm trying to open a USB storgare device but I'm unable. I went to my device manager and it says "Windows cannot use this hardware device because it has been prepared for "safe removal", but it has not been removed from the computer. (Code 47)" However the device has been removed. Can anyone help me fix the problem???
