Thank you BugRep ;-)
So for all out there that need to get it working on trisquel (in my case a
Huwaei E392 LTE Usb Modem (from TMN Portuguese provider) here's how:
type in terminal as root (or sudo the commands):
lsusb -v | less
Get the vendor and product ID from the result of the above command.
Like: Bus 003 Device 003: ID 12d1:1505 Huawei Technologies Co., Ltd. E398
LTE/UMTS/GSM Modem/Networkcard
Note the two references after ID (12d1 and 1505)
Now append this line in /etc/modules:
usbserial vendor=0x12d1 product=0x1505
(to edit type "nano /etc/modules" as root, add the lines, hit ctrl+o to write
the file (save) and ctrl+x to close nano.)
Reboot your computer and your done.
Set up a new mobile broadband connection and your online! ;-)
Greetings 2 all.
Thank you BugRep ;-)
