Hi Christian,

the problem that you describe is not a trivial one. When a driver registers 
itself with the kernel, it has to tell him which major and minor device 
numbers it will use. If a program now opens the corresponding device file, the 
kernel will activate the driver that is identifyed by this device numbers.

In such a situation, where two drivers use the same devicenumber, it does not 
help to change only the device number in the /dev directory. In fact, you have 
to change the device number in the driver regitration routine (module_init 
mostly) too. Search for the devicenumber in the source of the driver. If not 
available, you will have to inform the driver author about his mistake using a 
already acquired devicenumber.

If you don't need the device, that is also using the same devicenumber that 
the modem that you have problems with uses, you can also change the 
devicenumber for this one.

Hope I could help with this.

Joern Wuestenfeld
