VMware ESXi 6.0 – How can I pass-through (add) my Mac Pro’s optical drive to a VM (running OS X Mountain Lion)?

Bit unconventional I know, but I am running VMware ESXi 6.0 on my old Mac Pro 1.1. If you don’t know what that is then (no offense, but) you won’t be able to help me. The Mac Pro host has a “super drive” as its optical drive for CDs & DVDs.

I am trying to use VM pass-through to get my physical optical drive passed-through to the virtual machine. However, I have added the device to the VM and enabled pass-through, but still do not see it in the VM. What could I be doing wrong here? Thanks.
