Before we start, make sure your phone is in Data / Modem mode, and that it is not plugged in.
- Open a terminal, and make yourself a super-user.
> su - Now remove the usbserial module if it is loaded.
# rmmod usbserial - Let’s register the phones vendor and product ID with the usbserial module.
# modprobe usbserial vendor=0x22b8 product=0x2b24 - Plug in your phone.
If you type in ‘dmesg’ now, you should see that your phone was assigned a tty pointer. If so, your phone is now a modem.
