Ditto for me. I am using a Logitech PS/2 scoll-mouse which has a middle button by way of pushing the scroll wheel. Using the installation instructions include with the Cocolino has it working happy as a clam, and I have it set so a double middle-click changes screens.
I do not suppose that perhaps Elbox's insistence on the serial number is due to different revisions with different functionality? Otherwise, the software seems just "generic."
