My USRobotics 5410 (which worked perfectly out of the box with Breezy) does not work with Dapper at all (I installed it today from scratch and applied all upgrades using LAN). I found the solution <a href=http://www.ubuntuforums.org/showthread.php?p=860917&posted=1#post860917>here</a>. - The problem was with firmware, it had to be downgraded! (Note I am talking about native support, not ndiswrapper.)
