There is a bug in the Apple ExpressCard driver specific to 10.9 (and 10.9.1) that prevents ExpressCards from initializing in the MBP 6,1. We have reported it to Apple and expect Apple to fix it in a future release. In the meantime, we have a patcher for you.

Download the Qio System Installer here http://www.sonnettech.com/support/kb/kb.php?cat=402&expand=_a3&action=b496#b496

When you get to the installation type, click \u8220 Customize\u8221 , deselect everything but IOPCIFamily, and click \u8220 Install\u8221 . Restart and all should be well. When Apple updates the ExpressCard Driver, it will overwrite the old driver with the Sonnet patch, so there will never be a need to uninstall.
