I need to assign permanent names to some modems that I am working with. This would be possible by creating a rule in /etc/udev/rules.d/ and defining a symlink, something like this: KERNEL="ttyUSB[0-9]*", ATTRS{serial}="0000:00:1d.0", SYMLINK="Modem0" The problem is that all these modems have the same serial, so I cannot distinguish them and cannot assign a different symlink to each one. If it can help, the output of lsusb with two modems connected is this: Bus 006 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 005 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Is there a way to do this? Thanks. Theo
