482 @discussion This method copies data from the memory descriptor's memory at the given offset, to the caller's buffer. The memory descriptor MUST have the kIODirectionOut direcction bit set and be prepared. kIODirectionOut means that this memory descriptor will be output to an external device, so readBytes is used to get memory into a local buffer for a PIO transfer to the device.
