You must define the USB descriptors so the Host OS (Windows/Linux) loads the generic RNDIS driver.
Each Ethernet frame is prefixed by an RNDIS_MSG_PACKET header: remote ndis based internet sharing device driver
case RNDIS_INITIALIZED: // Check for Control Messages (Interrupt EP or EP0) if (CheckControlMessage()) HandleControlMessage(); You must define the USB descriptors so the
Since this is an "Internet Sharing" device, simply bridging packets might not be enough if the Host and External Network are on different subnets. You typically implement . The Remote Network Driver Interface Specification (RNDIS) is
The Remote Network Driver Interface Specification (RNDIS) is a protocol that enables a USB-connected device (e.g., a smartphone or embedded modem) to appear as a standard Ethernet network adapter to a host operating system. This article provides a complete technical overview of RNDIS-based internet sharing device drivers, including their protocol stack, control messages, data path, host-side driver implementation (Windows/Linux), and common troubleshooting methods.
RNDIS was developed by Microsoft as an extension of the NDIS (Network Driver Interface Specification) for bus-independent networks, particularly USB. It defines:
