Stopping modemmanager from auto probing?

[Torsten Spindler <torsten canonical com>]

Hello,

there seems to be a problem for some devices which modemmanager probes
over the serial line. Namely Palm devices [1] and a Smart Card reader
[2]. Is there any possibility to make the probing configurable?

There seems to be a work around available by removing 
/usr/lib/ModemManager/libmm-plugin-generic.so. This seems to prevent
modemmanager from doing the autoprobing.

Regards,
Torsten
