    I'm sorry. Oops was take place not after _eject_ CF, but after _disconnect_
    USB CF reader/writer...

    I wrote small script, which demonstrate described problem...

    ------- test-usb-storage.sh -----------
    #!/bin/bash
    SCSI_DEVICE=/dev/sda1
    MOUNT_POINT=/mnt
    IS_USB_STORAGE_DEVICE_UP=`cat /proc/bus/usb/devices | grep Driver=usb-storage`
    IS_MOUNT=`mount | grep $MOUNT_POINT`

    if [ "$IS_MOUNT" != "" ]
    then
    echo "$MOUNT_POINT mark as already mounted ..."
    echo $IS_MOUNT
    exit
    fi

    if [ "$IS_USB_STORAGE_DEVICE_UP" = "" ]
    then
    echo "USB storage device not found ..."
    exit
    fi

    mount $SCSI_DEVICE -t auto $MOUNT_POINT -o user

    if [ $? != 0 ]
    then
    echo "Can't mount $SCSI_DEVICE";
    exit
    fi

    echo Disconnect USB storage device now...
    while [ "$IS_USB_STORAGE_DEVICE_UP" != "" ]
    do
    sleep 1
    IS_USB_STORAGE_DEVICE_UP=`cat /proc/bus/usb/devices | grep Driver=usb-storage`
    done

    umount $MOUNT_POINT
    echo $?k !
    ------- test-usb-storage.sh -----------
