USB flakiness with binary release

[Eduard Martinescu]

So on my gentoo machine, I first installed the virtualbox-ose edition, setup a VM and had fun. I then decided to try to get USB support working, so I switched to the virtualbox-bin ebuild in order to get the full binary distrubtion. While running this version (both with and without USB support enabled in my VM), I ran into a very strange problem where at random times, my USB mouse would 'lock up' by jumping to the upper left corner of the screen and refusing to accept/register any movement. Mouse button presses would continue to work. Shutting down the VM would NOT solve the issue, but restarting the X server would. After having this happen many times within a few hours, I uninstalled the binary version of VirtualBox, and went back to the OSE edition. Since then, no such problems have happened.
