New SSD Installed, Can't Mount SD Cards Anymore (MBP 3,1)

I recently installed a SSD from OWC. The drive is great but I can't mount SD Cards anymore.

When I plug in my ExpressCard with the SSD in the MBP:

When I insert a SD Card, nothing shows up in Disk Utility:

When I run System Profilier with the SSD in the MBP:

What really gets me, is that when I replace the SSD with the original HHD that came with my MBP, SD Cards mount fine.

I'm using a MacBook Pro 3,1 (Late 2007) and both drives are running Mountain Lion 10.8.5. Thanks.
