Panasonic P2 Card reader not working after Yosemite upgrade

I upgraded my Mac Pro (Mid 2010) to Yosemite today. Everything worked fine, including Final Cut Pro 7 - I work at a post production facility. The only problem I have is that my Panasonic P2 Card Reader (AJ-PCD35) doesn't mount cards anymore. I installed the card reader in another Mac Pro running Yosemite and also couldn't get it to work. I installed the card reader in a third Mac Pro (running Snow Leopard) and it worked fine.

I have installed the latest driver from the Panasonic website and did a Firmware update. Is there anyway I can get this card reader tot work in Yosemite, or will I have to format and roll back to an older version of OS X?
