Sorry, I thought there was a "user" way to do this...

To get Windows driver sources, I think you have to sign an NDA with Telit.
Linux GSM/CDMA USB driver (usb/serial/option.c) is customized for 
working with Telit modules. The file I linked in my previous post:
http://www.telit.com/files/en/products/evk_drivers/Telit_UC_CC_DE_USB_Driver_for_Linux_U0_00_04_r3.pdf
tells that, for UC864-E, port ordering is: ttyUSB0=Modem port; 
ttyUSB1=Diagnostic port; ttyUSB2=Auxiliary port. It seems that they 
consider that this ordering is fixed (see table on page 10).

This is the serial port list (by-id) I have already posted. Supposing 
that we can consider this as persistent naming of module's ports... is 
still necessary to make udev rules?
