Just had the same thing happen to me. I did get it to install by installing through the N810's application manager. Did you install by going to the maemo site's downloads section? Try using the application manager through the settings tab from the N810 and go to "browse installable applications," select all, and scroll down to usb control.

BUT the problem I now have is that I've successfully installed the program, but absolutely nothing happens when I open the program..... See if you get the same results and let me know....
