Expresscard CF adapter compatible with Lion?

After upgrading to Lion I have found my CF adapter express card does not function. I need one that does. I have searched for reliable information about a compatible card to no avail. I'm irritated at Apple for not being helpful. Anyone know of an expresscard CF adapter that is reliably compatible with OSX 10.7.4?

There are many various inexpensive USB CF card readers that can be had, why not go that route instead? Express cards (any variety) are getting harder to find and finding one which works with the latest version of OS X is even more difficult.

Yes, I understand that there are plenty of USB readers out there. I need something that will let me deal with up to 64 GB of download at a time. I've appreciated the sped of express cards. I can't afford to wait on the USB speeds.

It's likely a driver issue. Contact the manufacturer and see if they have an updated driver.
