Here's what worked for me.
NOTE: kindle.sh will only work on KDE machines with a user called scott.
1. Plug in Kindle
2. Find device node
# tail /var/log/messages
grep -v Rej /var/log/messages | tail
Dec 15 22:08:05 vbserver mtp-probe: checking bus 1, device 9:
"/sys/devices/pci0000:00/0000:00:02.2/usb1/1-4"

not a recommended IO charset for FAT filesystems, filesystem will be
case sensitive!
(alternatively you could use # udisks --monitor)
sdb1 is the current device node (the value needed for the next step).
3. Use the KERNEL identification (top of the chain for the block mode,
in this instance /dev/sdb1) so the rule points to the block device
instead of the USB controller. Find identifiers specific to the Kindle.
# udevadm info -a -p $(udevadm info -q path -n /dev/sdb1)
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

The wanted values are:-
(from the device) ATTR{size}=="6410672"
(from the parent device) ATTRS{serial}=="B00AD0B11322188J"
We could use KERNEL=="sd?1" or KERNEL=="sd[a-z]1" to match on the device
node, but the serial number and disk size are sufficiently unique. See
man udev for explanation.
4. The first part of a udev rule is the matching keys. These positively
identify the Kindle (and match no other devices). The second part of the
rule is an action, in this case RUN.
NOTES: only properties from *one* parent of the device and from the
device itself. More than one value can be used. Custom rules should go
in /etc/udev/rules.d not /lib/udev/rules.d. I'm not using a symlink as
another rule already does that when it detects and mounts the Kindle.
====== /etc/udev/rules.d/81-kindle.rules ======
ATTRS{serial}=="B00AD0B11322188J", ATTR{size}=="6410672",
RUN+="/usr/local/bin/kindle.sh"
===============
Rule explanation:-
device serial must equal "B00AD0B11322188J"
device size must equal "6410672"
if so execute /usr/local/bin/kindle.sh
NOTE: RUN is dumb - give a full path or udev assumes the path begins
with /lib/udev.
======= /usr/local/bin/kindle.sh ======
#!/bin/bash
su scott -c 'export DISPLAY=:0 && kdialog --icon calibre-gui --title
"Kindle" --caption "Status" --msgbox "The Kindle is ready"'
su scott -c calibre
=======================================
5. Change logging level
# udevadm control --log-priority=debug
logs to watch:-
/var/log/daemon.log
/var/log/messages
6. Plug in Kindle
Kdialog pops up, then Calibre loads. If you have no such success look at
the logs.

Kind regards
