You should be able to use “usbnet” to talk to these gadgets from Linux hosts, and its device side acts much like the iPaq scenario described here. Here’s what one looks like. Those two systems connect through USB network links, and the configuration problem is making sure there is complete IP connectivity. Generally it is best to build USB gadget drivers as modules instead of building them into the kernel so you can unload one and load another. Ongoing support is also available. Thank you very much in advance! Be careful using Bridged configurations with PDAs.

It also eliminates the need to route a two-node subnet for each new USB network device, hos network administrators happier with llnux choice of peripheral hardware.
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.
The first part of bridge setup makes a logical LAN during network startup. That uses a USB host-to-host cable.
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.
Here’s what one looks like. In this and other ways, the Remote NDIS specification allows for a wide range of device functionality and performance levels.
How to use USB device networking
Get the right network settings from your local network admin. They’re not GUI tools, but they’re a better start than what’s sketched here. It should just initialize, so that you can immediately use the device as a network interface. As a standard network link, you could just configure it for use with IPv4. Seek out other options if you can.

If there is published information, tutorials, or mailing lists, those will likely be findable via the latter. So I did little change. In current Linux it’s now a generalized core, supporting several kinds of network devices running under Linux with “minidrivers”, which are separate modules that can be as small as a pair of static data tables.
And maybe changing vendor and product IDs. Many people will be familiar with PDAs running Linux, discussed later in this section, but the embedded system lonux need to be a PDA.
In addition to the “software emulated” adapter model used in smart peripherals, there are also single-purpose adapters using rnfis hardware.
They act as Hosts in the networking sense while they are “devices” in the USB sense, so they behave like the other end of a host-to-host cable. Ethernet adapters, or devices that run like them many cable modemswould normally use names like “eth0”.
You can set this with:. That rndos, this appears like a normal Ethernet link, not like a point-to-point link. Unless you listen to Microsoft, who will tell you not to use such vendor-neutral protocols. Ongoing support is also available.
Run wireshark on your host PC monitoring the usb0 interface and you don’t need any packet filters. You can use ip link set usbN name newname or similar tools.
Similar setups can rdis DHCP. This page was last edited on 13 Augustat One type is a host-to-host network cable. It’s incomplete because Linux doesn’t need to know anything specific about products correctly implementing the CDC Ethernet class specification. This maybe cause udev not working Among other things, that means that if there’s more than one such PDA in use at your site, everyone who may be bridging one of them should override that non-unique address.
If something isn’t working, you will see the last packet that was sent and not responded to. Those are good to understand, since some other devices described here oinux 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.
