No, not yet,
I´ll dive into it.
Come to think of it, Old-Polack mentioned something similar
a while back in another thread.
Anyway, I'll report back.
Thanks, Hoos.
I have it on good authority he also posted about installing the
libpython2.5-devel package,
before running the
installation script, so that VBox would build
without errors. Missed that one, didn't you?

3.2.2 and 3.2.4 both had usable USB after installing the
libpython2.5-devel package. You may need to run the current guest additions while the VM is running, and may also have to reboot the host machine as well as the guest VM before the USB works, but it will work.
When I replaced the
3.2.0 installation with
3.2.2, the USB attached items just
worked, using the
older guest additions. When I upgraded to the
newer guest additions, the USB items
grayed out and remained so after a
reboot of the VM. Rebooting the
host corrected that. With the upgrade to
3.2.4, the
same thing happened. It needed a
full reboot of the
host before the USB attached hardware was
fully recognized and operational with the
newest guest additions.
