I confirm for the "whole xperia" affected aspect.
I have Xperia Play, and the same matter occurs.
Just for info, I copy libmtp rules from /lib/udev/rules.d/ to /etc/udev/rules.d/ and add the entry for Xperia play but matter still remains.
product id is 515d (when USB debugging in on) and 015d (when USB debugging is turned off).
