Steve, should it make a difference if the driver is installed while in a FileVault account or not? I started in Safe Mode to see what would happen and the b6 driver isn't recognized in the FileVault account while it is recognized in a normal account after the restart from Safe Mode startup. There were a number of things removed by Safe Mode. Many of which were dated the day that I upgraded to OS X.4.11 from X.4.10, and installed Security Update 2008-002. My Logitech mouse doesn't work correctly, nor is it recognized, in the FileVault account either, but it is seen in the normal account, and it works fine. Any thoughts? I can send you a screen shot of what was put in the trash if you would like. I haven't emptied it yet.<br>
