Hi @imthernet,

if you’re familiar with (re-)building your own kernel modules you could use these mainline Linux kernel patches

Hey, can you explain how to install the linux drivers using these patches? I am a new user.

Hi. You don’t need to rebuild the kernel. I solved it with binding current kernel drivers to existing USB ports.

echo 2c7c 0801 ff > /sys/bus/usb-serial/drivers/option1/new_id
echo 1-1.3:1.4 > /sys/bus/usb/drivers/option/unbind
echo 2c7c 0801 ff > /sys/bus/usb/drivers/qmi_wwan/new_id

Take USB ID 1-1.3:1.4 from syslog. It means 4th interface (port) of the usb device sitting on 1-1.3. I.e. it is QMI WWAN+QMI CDC.

so you will get wwan0 , /dev/cdc-wdm0 and /dev/ttyUSB2 (AT port).
