Yes, this is what the driver does in the background if you do not pass any "-D" flags. If you were to start `upsd` at that point, it should be able to provide data to clients like `upsc`. However, since you needed to pass `-u root` to the driver, you may need to pass `-u root` to `upsd` as well.

I am not sure which component is at fault: NUT for not resetting something (though the automatic close-on-exit behavior in the OS should take care of this - or at least, it has in every other case I am aware of), libusb or FreeBSD for not cleaning up, or the UPS for not recovering properly.
