I have a HUAWEI Modem E3531 Modem Dongle .
I am not able to switch it to usb_mode using usb_modeswitch -b2 -W -v 12d1 -p 14dc -n –message-content 555342437f0000000002000080000a11062000000000000100000000000000.
Product ID is 12d1:14dc
What are the switching rules or how do I achieve this? I am using Ubuntu 16.04 and i need to access the modem like on ttyUSBx . So that in kannel.conf i can point to it say at ttyUSB2.
URGENT.
