Chase, mine is a Optiarc DVD RW AD-7640S.
As far as I know no firmware upgrades are available. On http://www.sony-optiarc.eu/ I can't find the AD-7580S nor the AD-7640S. Optiarc refers to the reseller. Mine has no updated firmware, but then they probably don't care since it seems to work in Windows.
