I want to install the driver of EP06E mPCIe on Siemens IOT2050 example image V1.2.2 (OS: Linux Debian 5.10.64 aarch64). Yet I can’t find the derictory “[KERNEL]/drivers/usb/serial/usb_wwan.c” as discribed on LTE&5G_Linux_USB_Driver_User_Guide_V2.0 file.
I am a beginner with linux and would appreciate any support to sort this out.
