Yes, Greg asked me for this output and I sent it to
him, this way he told me it should work with the
cdc-acm module, but no, he said nothing about the
Sub=03 issue...

I've got no idea, I don't know that much about the
inners of
any modem driver/mode.... That's why I asked for help
:O.
I'm not that knowleageble of drivers and such...
PS: I add Greg to the CC, in case he missed the Sub=03
thing.
In case it where so "easy" as to add the "Sub=03"
somewhere,
where should it be added? HAL? The kernel?
Thanks for your help!
