Home – linux – gumstix. As shown here, nothing happens if there’s no “lan” bridge; so this change could go into config files on any system that might ever use a bridge called “lan” in this particular way. Unfortunately we can’t expect such bugs to get fixed by Microsoft. If it doesn’t, then you probably didn’t configure this driver or its modular form into your kernel build. Since that’s the only USB networking protocol built into MS-Windows, it’s interesting even though it’s a proprietary protocol with only incomplete public documentation. The “usbfs” style device naming has problems since it’s not “stable”:

Two devices with different brand labeling on the box and device may look identical at the USB level. You can often open them up to look. Linux has a fully featured IEEE A bridged configuration will be less error prone. The rest of these configuration instructions are oriented towards devices that are not very “ethernet-like”. That’s the preferred solution for Zaurus interoperability.

The bridge may cause a short delay one document said thirty seconds before you can access the new devices, and should quickly start forwarding packets. Cookies help us deliver our services.

Another approach to using IP over USB is to make the device look like a serial line or telecommunications modem, and then run PPP over those protocols.

Note that while many USB host-to-host cables can work in this mode, that may mean not being able to talk to Win32 systems or more commonly not being able to handle certain events like replugging the host on the other end very well. With older kernels, just “modprobe usbnet” to get everything; newer kernels modprobe the minidriver, which depends on usbnet to do all the USB-specific work.


If it doesn’t, then you probably didn’t configure this driver or its modular form into your kernel build. In particular, lijux a lot of ARM chips have direct support in Linux 2. If you install an alternate image, such as the Linux 2. Similar setups can use DHCP. It should just initialize, so that you can ilnux use the device as a network interface.

Linux source code: drivers/net/usb/usbnet.c (v) – Bootlin

The host side initialization in those cases is exactly as shown earlier, since the host uses the “usbnet” driver. And for ljnux reason, vendors seem to dislike using standard framing in their Windows drivers, so many minidrivers need to wrap a technically-unnecessary layer of headers around Ethernet packets for better interoperability.

I modified the network startup code to bring up eth0 as the core of bridge, instead of calling “ifup”. That’s done for linus reasons, most of which boil down to making it easier to bridge these links together.

However, I don’t need it anymore because a colleague of mine already started rebuilding the kernel: Another way to package these devices takes a bit more money to provide two “B” connectors. This driver makes the adapter appear as a normal Ethernet interface, typically on eth0, if it is the only ethernet device, or perhaps on eth1, if you have a PCI or ISA ethernet card installed.


I also tried disabling MAC filtering on the wireless router, but it didn’t make any difference.

How to configure the Linux kernel/drivers/usb/net

That is, this appears like a normal Ethernet link, not like a point-to-point link. It can be found this directory: You might have noticed that the MS-Windows driver provided with most USB host-to-host cables implements a limited form of bridging. Except that the interface name is likely usb0 instead of usbf or usbd0.

You can use the ifconfig command on the gumstix to determine the MAC address. Basically, they’re missing the extra electronics shown above, which is necessary to let usbnwt USB “master” host talk to another one, by making both talk through a USB “slave” device.

That ALI code seems to need a seven byte header that nobody’s taught Linux to use.
