Comment 14 for bug 446146

Hi Benjamin, I do not want to 'gain' from your knowledge but if possible can you take a look to bug:
https://bugs.launchpad.net/bugs/408555
that has a similar 'looping' on creating/disconnecting ttyUSBx with ZTE MF636? The difference there is that ttyUSBx is advanced (+1) at a time reaching ttyUSB8-9-... and finally the system gets frozen.
Thanks in advance,
George
