I have a problem with enabling USB on my VirtualBox installation on Ubuntu 11.10 x64.
The picture above basically shows the error being shown on the 'Terminal' after I click OK on the 'vboxusers' Properties. I tried it many times showing the same exact error.
(users-admin:11567): Gtk-CRITICAL **: IA__gtk_list_store_set_valist: assertion `VALID_ITER (iter, list_store)' failed
Can somebody help me? I'm new to this thing and I already tried the method shown in this forum.
