Very simply, I turn it on, it de-syncs.
I turn it off, it doesn't.
Does this in windows 7 and 8. In 8 things stop working. (maybe an EFI related thing I dont understand?)
And im not completely sure of all the new additions to ubuntu 12.10, but when i turn it off, everything stops working. (select USB devices included.)
