superdrive(s) not working after mavericks install?

After installing Mavericks, my internal superdrives will not function properly. I have two superdrives installed on my Early 2009 Mac Pro with 2.93 GHz quad core Intel processor. I insert a disc, close the drawer, I hear some whirring/spinning sounds, then the drawer opens up. Same result with either drive.

I was trying to install tax prep software, get the same non-function if I try to run music CD. Cleaned the lens with compressed air, and also a CD Laser Lens Cleaner disc.

I use the drives occasionally. However, the last time, prior to Maverick download and install, both drives worked fine.

Are the drives supported by Mavericks? Should I reset the SMC?

I have looked through some recent threads, and this issue seems to come up with increasing frequency, with many varied and sometimes conflicting results. I noted with some chagrin one pragmatic response of buying an external optical drive and forgoing the attempt to regain function of the factory-installed superdrives. Perhaps I didn't delve far enough into prior threads to find an answer.

What are other's doing?
