Thank you very much Sir
The fact is, the devices.txt file is not in the /etc/udev/makedev.dev/
directory. It is in the /usr/share/doc/MAKEDEV.DEVS-something_like_that
directory, but I presume there shouldn't be any difference.
Anyway, the /dev/ttyACM* devices are not being created after the
theoretically USB ACM compatible modem is switched into USB.
However, the network tool interfaces list shows only input/ttyACM[0-9]
( inside the input directory ), but there is no ttyACM device inside
the /dev/input/ directory anymore
The devices.txt file I previously mentioned, effectively shows
the /dev/ttyACM* devices, but I don't know how to create them.
Whenever I do a: "MAKEDEV ttyACM", this message appears:
"I don't know how to create this device."
I presume the devices.txt is found, otherwise the message should have
indicated "File not found" or something like that.
Maybe the /etc/udev/rules.dev/ rule file should be setup, such that
the proper rule could be used to create the interface.
I tried to add a same line as "ttyUSB*" line, but with "ttyACM*" in
this file, but it failed.
I don't know the way to complete the configuration files, to be able
to setup the /dev/ttyACM0 interface.
Can you help me ?
Thank you very much.
Best regards.
