As I said, cdc-acm is not satisfied with this kind of device. I do not know
how to make it work. Also usbserial didn't work. How could I make them work?
Please, note that the same command, used when the gprs modem is disabled (so i
am using ipaq module in this case), gives:

which is, for what I understand (not to mutch to say the truth) really
different.
Obviously I will be happy to make all the test you will ask me.
