Hey,
I would like to use two or more ttyUSB devices. Each device has a special function (one for 3g, one for USB <> 3G), so I need to assign a static name to each device.
Example:
The 3g dongle should always be /dev/ttyUSB0
The USB RS232 Adapter is always /dev/ttyUSB1
Im using the latest stable version on a TP-Link TL-WR1043ND.
Thanks for your help!

You can write a hotplug script.
Hey,
I just tried that, and it worked fine at first. But the symlink seems to alter the data format.
If I use
read LINE < /dev/ttyUSB0
model=`expr substr $LINE 11 11` # Model
everything works fine.
If I use
read LINE < /dev/CCD
model=`expr substr $LINE 11 11` # Model
which seems totally equal viewed with cat, the expr substr fails.
What do I have to change to make it work both ways?
The discussion might have continued from here.
