IBM UltraPort Compact Flash Adapter

This is a Compact Flash Card Reader for the IBM UltraPort. It can also be connected to any USB port by using the included cable.

  • Transfer rates up to 900KB/s reading and up to 470KB/s writing
  • UltraPort and USB interfaces

IBM Partnumbers

IBM FRU PN: 19K4510

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:

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

Furthermore, enable USB support:

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

Choose an appropriate USB host driver, one of:

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

Finally, enable the USB Mass Storage driver:

CONFIG_USB_STORAGE → <M> → USB Mass Storage support → USB support → Device Drivers
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.
