I have experienced problems with USB also. My guest is Windows 8.1. When I try to access the USB device from Windows, the access fails and then everything inside the VM seems to start misbehaving. I cannot properly shutdown the VM - I have to kill the VBox process. If I don't try to use the USB device, everything works fine.
