ECM,NCM:根据网络资料,这两个是Linux下的“NDIS”标准。ECM是Ethernet Networking Control Model的简称,NCM是Network Control Model的简称,后者是包含前者的。 可以看出,ECM、NCM在USB上是要满足CDC要求的,如果出现CDC-ECM,按这种思路,就比较好理解了。进一步的,作为标准,如果内核支持这种方式,显然就不需要额外的驱动...
注意ECM/NCM/RNDIS 等不同模式下的 PID 是不一样的。需要根据模 组的模式添加相应的 PID/VID(请参考 USB 端口章节),或者可以把 FM650 支持的所有模式 ID 都添加上去。

A general use case of a CDC NCM device is a Wireless Network Adapter which supports 3.5G/4G networks such as: HSPA+ and LTE. (4)OBEX (Object Exchange) is compliant with the Wireless Mobile Communication OBEX function model, supporting OBEX applications over USB. ...
(3)CDC-NCM (Network Control Model).The NCM (Network Control Model) protocol is used for exchanging High Speed Ethernet-framed data between the device and host. A CDC NCM compliant device exposes itself as a virtual NIC to the host operating system. The NIC is assigned with a MAC and an...

RNDIS的框架如下: RmNet RmNet是高通公司为其手机平台开发的专有USB虚拟以太网框架。 RmNet通过薄层协议(TLP)提供更高的吞吐量,并允许服务质量流量控制。 RmNet和CDC-ECM区别:更像是两种拨号方式的区别,RmNet获取公网IP,CCD-ECM获取局域网IP。 在高通平台上,rmnet 也是属于CDC-ECM,他们具体的区别在于对于USB命令的封...
The engineer who mainly worked on this left some work unfinished, ie here we wanted to remove support for ECM/RNDIS because it was never implemented in esp_tinyusb in a first place espressif/idf-extra-components#235 ATM, we want to upgrade to TinyUSB v0.17 which contains refactored NCM dr...
