Ok, I can reliably reproduce the problem as follows:
* connect the kindle, it goes into usb disk mode
* !!! important !!! use the temporary gnome3 dbus window to "Eject"
the device
after that the device is not really ejected
* use "eject /dev/sdb"
after this the device is actually ejected
* unplug and replug
here the usb system does not recognize the device anymore, and
does not react on any usb connections
* call lsusb -v gets it back to normal
* repeat the above
I have collected the syslog output of one of the cycles starting from
lsusb -v to get back to normal, plugging, ejecting with dbus window,
eject with cmd line, plug/replug without effect, etc.
The log can be found at
http://www.preining.info/usb-syslog-prob.txt
I have documented the steps *in* the log file by calling
logger ....
with the appropriate steps, so please seach for
norbert:
which will give you the comments I have written with logger and
the sequence of actions.
Hope that helps, and let me know if you want/need more details.
Norbert
