I'm having trouble reading Compact flash and SD cards on the

Wherever the state is kept, it's not in the module. modprobe -r
usb-storage; modprobe usb-storage gives a kernel message about
"compact flash" even though the only medium in the reader is an
SD card.

Are you sure that this card reader supports both types of cards simultaneously? Some/many/most card readers share signals between the connectors to save pins on the IC package.
