Instead, it will have been “locally assigned” during initialization of the “usbnet” driver. If it doesn’t, then you probably didn’t configure this driver or its modular form into your kernel build. That’s the preferred solution for Zaurus interoperability. Since that setup doesn’t use “ifup” to bring interfaces up, you don’t need to manually set up each potential usb link. The other is a “host” that sits on some LAN, and probably has Internet access. You probably don’t want to administer routing machinery except when you’re deploying some kind of firewall.

CONFIG_USB_NET_RNDIS_HOST: Host for RNDIS and ActiveSync devices

Some systems aren’t robust with zero length packets. One such boot loader is BLOB. Notice that this has two “A” connectors built in, as well as the special device inside the molded plastic; use your X-Ray goggles. A bridged configuration will be less error prone.

The GNU/Linux “usbnet” Driver

You’ll need to do that by hand, since most sysadmin tools don’t rnsis bridge configuration. By using our services, you agree to our use of cookies.

In current Linux it’s now a generalized core, supporting several kinds of network devices running under Linux with “minidrivers”, which are separate modules hoost can be as small as a pair of static data tables. Belcarra Technologies – www. The latest version of the usbnet driver include support for some firmware that Epson provided to help ohst applications using Epson SOCs interoperate better with Linux. Unless you listen to Microsoft, who will tell you not to use such vendor-neutral protocols.


Many people will be familiar with PDAs running Linux, discussed later in this section, but the embedded system doesn’t need to be a PDA. Before connecting the target device to the host PC, watch the syslog, by running the following command on the host PC:.

How to use USB device networking

So now it re boots into the right configuration, but this setup won’t play nicely with RedHat’s tools. Navigation linud Personal tools Log in.

Please log in or register to answer this question. You might want to try ECM networking mode. Since that setup doesn’t use “ifup” to bring interfaces up, you don’t need to manually set up each potential usb link.

Hoat could be a home gateway, or any other kind of device or gadget where embedding Linux can give your product an edge.

Enabling USB RNDIS Support – ARM9 Based Platforms – Critical Link Support

The first part of bridge setup makes a logical LAN during network startup. Because it works with Microsoft’s standard RNDIS host driver available for all of Microsoft’s currently supported Windows operating systemsrncis extra software need be loaded on the host machine, lowering license costs and support problems. It only needs to wrap network packets in one of a few ways, without many demands for control handshaking. The problem only comes up with code derived from that Zaurus work.


The PDA side initialization is a bit different, but the host side initialization and rndiss of the other information provided here stays the same.

Is there any good resource for me? Be careful using Bridged configurations with PDAs.

Stack Overflow works best with JavaScript enabled. If you’re using Ubuntu or Debian, you’re lucky to have some decent examples of how to set up bridges as part of your “ifupdown” documentation.
