Linux driver

The Compact Flash Card Reader is accessable via the USB Mass Storage driver, just like a usual USB memory stick.

Since the USB Mass Storage driver is SCSI based you'll need SCSI support in your kernel. Enable the following options:

Device Drivers → SCSI device support → [M]SCSI device support (CONFIG_SCSI)
Device Drivers → SCSI device support → [M]SCSI disk support (CONFIG_BLK_DEV_SD)
Device Drivers → SCSI device support → [M]SCSI generic support (CONFIG_CHR_DEV_SG)

Furthermore, enable USB support:

Device Drivers → USB support → <M>Support for Host-side USB (CONFIG_USB)
Device Drivers → USB support → [*]USB device file system (CONFIG_USB_DEVICEFS)

Choose an appropriate USB host driver, one of:

Device Drivers → USB support → <M>ECHI HCD (USB 2.0) support (CONFIG_USB_EHCI_HCD)
Device Drivers → USB support → <M>UHCI HCD support (CONFIG_USB_UHCI)
Device Drivers → USB support → <M>OHCI HCD support (CONFIG_USB_OHCI)

Finally, enable the USB Mass Storage driver:

Device Drivers → USB support → <M>USB Mass Storage support (CONFIG_USB_STORAGE)
NOTE!
Make sure that the Low Performance USB Block Driver (BLK_DEV_UB) is disabled. It would prevent the whole thing from working correctly.

Compile your kernel with these options (don't forget # depmod -ae) and reboot or just load the relevant modules (scsi, sd_mod, sg, usb, usb-ehci/usb-uhci/usb-ohci, usb-storage). If you didn't already, plug in the card reader and insert a CF card.

Do a # cat /proc/bus/usb/devices to asure yourself that your card reader is recognized by the USB subsystem.

Now also check if the USB Mass Storage driver is working properly by doing a # cat /proc/scsi/scsi.

Usually, your card reader will be associated with /dev/sda and hence it's first (and mostly only partition) will be /dev/sda1. You can check that using the sg3_utils.

You may want to put an entry in your /etc/fstab, i.e. with the above assumtions:

/dev/sda1   /media/cf   auto   noauto,users    0  0

That's it. Your card reader should be working now.
