INFO
QUALCOMM 3G/4G
Config Background
Available modes of the device are RNDIS and CDC-ECM.
RNDIS is a Microsoft proprietary protocol used mostly on top of USB. It provides a virtual Ethernet link to most versions of the Windows and Linux operating systems. A partial RNDIS specification is available from Microsoft, but Windows implementations have been observed to issue requests not included in that specification, and to have undocumented constraints.
CDC-ECM is Ethernet over USB.[1]
Device Modes
End-User Mode: Enumerating CDC-ECM interface - In this mode, the device is used for a WWAN connection to the Internet for such activities as browsing or connecting to a VPN.
pacman -Sv usb_modeswitch lsusb sudo usb_modeswitch -v 0x1410 -p 0x9020 -u 2 ip link sudo dhcpd in73rf4c3
Enterprise Mode: Enumerating CDC-ECM and Modem interfaces (Optional) - In this mode, the Modem interface allows users to send AT commands to the device to configure, query, or manage the Internet connection.
I do not understand Enterprise mode, they say CDC-ECM AND modem interfaces? Does it give both interfaces at once? The guide asks you to compile option.c and usb-wwan.h which are definitions for USB serial mobile broadband cards. It just involves adding a driver line that associates the device with the driver.
