Hello everybody,
I have a little problem and need some help to solve it. Any suggestion will be greatly appreciated. :)
I am using kubuntu 13.10
I am working with a couple of modems which are connected to the computer through a USB/UART cable.
I am trying to assing permanent names to these modems. Everytime that I connect I would like to obtain them something like /dev/Modem1, /dev/Modem2.
I have read that this is possible changing some rules in /etc/udev/rules.d/, but unfortunately from udev I cannot get a different ATTRS{serial} for every modem so I cannot distinguish one modem from another.
The only thing that I was able to do is assign a permanent name to the usb-port, but this does not solve the problem.
I tried the commands
$ udev -a -p /class/tty/ttyUSB0
$ udev -a -p /class/tty/ttyUSB1
$ lsusb
Here I attached the results.
MODEM1:
$ udev -a -p /class/tty/ttyUSB0
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
