External DVD drive not working post-Mojave update

Ever since I updated to Mojave, my external DVD drive no longer works. I am using a Late 2016 MBP w/ Touch Bar (4 Thunderbolt 3 ports). When I plug the DVD drive in, I can tell that it makes the disc spin, but it no longer shows up in Finder (i.e., the drive/disc never mount).


Here is what I've already tried:


1.) Double checking finder preferences to make sure external drives will show up

2.) Trying the DVD drive on another computer (PC). It works on PCs, so the drive isn't the problem.

3.) Trying different USB ports on the MacBook


The same drive always worked before Mojave. I'm wondering if Mojave reduced the power available for USB accessories.


Anyone else having this problem? Any solutions?


PS: Yes, DVDs are antiquated at this point, but I have no choice in the matter.

MacBook Pro (13-inch, Late 2016, 4 TBT3), 27" external 1080p display HDMI

I'm having the same problem on my 2017 iMac. The external DVD drive is Apple model number A1379 and it's only a couple years old. It worked fine before I installed Mojave. The drive no longer shows up in Finder. I've tried the obvious things like restarting and plugging into different USB ports. The drive shows up in Disk Utility, but the buttons for First Aid, Mounting, etc. are grayed out. The same is true for my co-worker's iMac. I really hope we don't have to buy new external drives. We work with large files that need to be given to vendors and DVDs are the easiest way.
