I'm not going to extract the information from debian-user. Those should 
be provided by you in the bug report.

What's the actual device name?
Please post the output of
udevadm info -a /dev/<DEVICE>
and
udevadm info /dev/<DEVICE>


What the debug output of systemd-udevd when you attach the device?


This command will allow one to observe the execution of rules:

udevadm control --log-priority=debug
journalctl -f

(and udevadm control --log-priority=info to set it back to sane levels)
