Like overengineering. It would lead to "board_usb_init(USB_INIT_ALL,
USB_INIT_DEVICE, USB_CLEANUP)" calls, which are not very readable.

Despite our greatest ambitions, I don't think we're likely to use more
than 2^31-1 USB controllers at a time. Besides, negative values look
better both in code and debugger session.
