Is there a special compile-config option that I have to enable inorder to get USB 2.0 working? vboxmange list extpacks shows that my extension pack is installed and usable, and I'm not getting any runtime errors or even warnings.
I've been trouble shooting this problem for two days now and I only managed to isolate the problem to VBoxC.dll. The only way I was able to get USB 2.0 to work is by replacing my VBoxC.dll with the one packaged with the virtualbox install. Here is my info: VirtualBox 4.0.4 -- Self Compiled Windows 7 x64 Thanks!
