Some WWAN LTE/3G devices based on chipsets from Qualcomm provide near standard CDC ECM interfaces in addition to the usual serial interfaces. The Huawei E392/E398 are examples of such devices. These typically cannot be fully configured using AT commands over a serial interface. It is necessary to speak the proprietary Qualcomm MSM Interface (QMI) protocol to the device to enable the ethernet proxy functionality. The devices embed the QMI protocol in CDC on the control interface, using standard CDC commands and notifications. The do not otherwise use CDC commands for the ethernet function. This driver does therefore not need access to any other aspects of the control interface than the descriptors attached to it. Another driver, cdc-wdm, will provide userspace access to the QMI protocol independently of this driver. To facilitate this, this driver avoids binding to the control interface, and uses only the associated data interface after parsing the common CDC functional descriptors on the control interface. You will want both the cdc-wdm and option drivers as companions to this driver, to have full access to all interfaces and protocols exported by the device.
