Noticed this on a "Lenovo Ideapad S10" as well. Ubuntu #925760 has a workaround
for this:

$ rmmod ums_realtek

 usbcore: deregistering interface driver ums-realtek

And the messages stop. As soon as the module is loaded again, the messages
resume and repeat every 52 seconds:

$ modprobe ums_realtek

May  2 23:50:46 scsi5 : usb-storage 1-5:1.0
May  2 23:50:46 usbcore: registered new interface driver ums-realtek
