Speaking in broad terms, it's normal to see new device connection and configuration messages like the ones above when a USB device is plugged in to your computer. What's not normal is to see disconnects. So you should be concentrating on what happens just before the log entries you posted -- why is the card reader disconnecting? Turning on CONFIG_USB_DEBUG may provide more help.
