Description
If the Extras pack is not installed, it is perfectly possible to START a VM that has USB configured. It warns that USB will actually be disabled, and gets on with it. Everything works fine.
If you then make a snapshot and try to restore it, it will say that USB is enabled but not installed, and hence the snapshot cannot be restored. I haven't found a way to convince VirtualBox to disregard USB, so for now it's a snapshot-loss bug, which is quite serious.
"Implementation of the USB 2.0 controller not found!"
Result Code: E_FAIL (0x80004005) Component: Console Interface: IConsole {515e8e8d-f932-4d8e-9f32-79a52aead882}

That's a duplicate of #8182. Actually we should never have allowed the user to start a VM with USB enabled but without the Extension Pack installed. This will be fixed in the next maintenance release. For fixing your VM have a look at #8182.
