Here’s an incomplete list of devices that the usbnet driver works with. Those are good to understand, since some other devices described here need to be administered like those cables; Linux bridging is a useful tool to make those two-node networks more manageable, and Windows XP includes this functionality too. Belcarra provides custom and new proprietary or GPL bus interface drivers for new or modified chips and chip-sets. Stable names let you build systems with logic like “since this link goes to the test network, we will firewall it carefully when we bring it up”. If it doesn’t, then you probably didn’t configure this driver or its modular form into your kernel build. To debug my embedded linux system, I’d like to find a resource which describes about the overview of host RNDIS driver.

Once that driver starts using that USB device, you’ll notice a message like this in your syslog files, announcing the presence of a new usb0 or usb1usb2etc network interface that you can use with ifconfig and similar network tools. The second part of bridge setup makes hotplugging add all USB interfaces to that bridge.

However, if that system does run Linux you can use the new USB Gadget framework to develop drivers there. Views Read Edit View history. Yes, you may occasionally see “A-to-A” cables for sale; don’t waste your money buying them.

It’s incomplete because Linux doesn’t need to know anything specific about products correctly implementing the CDC Ethernet class specification.

With older kernels, just “modprobe usbnet” to get everything; newer kernels llinux the minidriver, which depends on usbnet to do all the USB-specific work. The only way you can legally connect one host to another is through one of these special devices which accepts commands from two hosts rbdis the same time.


You might have noticed that the MS-Windows driver provided with most USB host-to-host cables implements a limited form of bridging. The PDA side initialization is a bit different, but the host side initialization and most of the other information provided here stays the same. See also this page about handling such hotplug issues, mostly with Debian and wireless. Except that the interface name is likely usb0 rneis of usbf or usbd0. It partially supports the goal of a fully hands-off user install experience, so that USB peripherals don’t require any sysadmin attention at all during setup, even on networks without DHCP service.

If you try to use one, you might even short out your USB electronics and so need to buy a new system. If that device talks like one of the host-to-host adapters listed above, a host won’t know it’s talking to a PDA that runs Linux directly.

There is a lot of information on how the Internet giving more detailed ,inux. Please log in or register to add a comment. On your host PC, you need to make lknux the That is, this appears like a normal Ethernet link, not like a point-to-point link. Wireshark is your friend.

If you’re using Ubuntu or Debian, you’re lucky to have some decent examples of how to set up bridges as part of linhx “ifupdown” documentation.

That will give you a big hint as to where to start looking for the problem. It can enhance the overall stability of the system since no new drivers are required and there are no drivers for the end user to install to support the new USB-connected network device.


That’s because they connect to two different hosts, not just one. The link level address will usually not be one rndsi a manufacturer’s ID prom, except on higher end devices.

Linux Remote NDIS USB device function driver now available from Belcarra Technologies []

For dynamically assigned Ethernet addresses, that can’t work; using “bus-info” is the appropriate solution. Post as a guest Name. This is the default framing, used with most devices. Host-to-host cables automatically use pairs of unique “locally assigned” IEEE addresses, and do not cause such problems.

This is different than a root NFS mount. It should just initialize, so that you can immediately oinux the device as a network interface. Those two Zaurus-specific drivers use nonstandard framing for Ethernet over USB, although the “eth-fd” driver enumerates as if it were conformant with the CDC Ethernet specification.

Toggle navigation Forum Navigation. The rest of these configuration instructions are oriented towards devices that are not very “ethernet-like”.

How to use USB device networking

To debug my embedded linux system, I’d like to find a resource rndia describes about the overview of host RNDIS driver. That ALI code seems to need a seven byte header that nobody’s taught Linux to use. Then I shut down the zero, add again a file called “ssh” in the directory and connect it to my Ubuntu Machine.
