8182	Unexpected error about USB 2.0!	Edward Yang		"It's really strange (again). I had successfully started the guest OS, and shut down at least 2 times (because I remember installing the new version addition). Last I saved the state and now I tried to resume it, I got this error:


Failed to open a session for the virtual machine Windows 7.
Implementation of the USB 2.0 controller not found!
Because the USB 2.0 controller state is part of the saved VM state, the VM cannot be started. To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack' or disable USB 2.0 support in the VM settings (VERR_NOT_FOUND).
Unknown error creating VM (VERR_NOT_FOUND).


What's the meaning of it? I had already several times of startup/shutdown, yet it complains about USB 2.0 support if I save it?"	defect	closed	other	VirtualBox 4.0.2	fixed			Windows	Windows
