That is precisely the same "TSSTcorp CDDVDW SU-208GB" drive that Mike has. None of the fixes worked for him, either - yet on May 11 the drive began to work to everyone's delight. Could be one of the fixes kicked in a tad late, could be something updated on its own in the background. Anyway...
What is your computer make & model?
You should go to its site for any driver & firmware update. Current BIOS version is in MSInfo32 (ask Cortana). For driver updates, if one is a greater version at the site, first try to get it using Device Manager (search automatically). If it won't come in that way, take it from the site.
