USB ethernet adaptors

Wired network connectivity can be an advantage, as wireless connectivity might not always be available or troublesome to set up. This requires an USB Ethernet adapters.

General remarks

Not all USB Ethernet adapters found e.g., on eBay work "out of the box" with the XO laptop (especially the cheap USB 1.1 ones), so let's list devices that are known to work here.

Note: You might need to reboot your laptop after inserting the adapter. This may not be plug-and-play! On the other hand, do check before you reboot, it might already be working, as per "rtl8150" support above.

Keep in mind that some vendors will change the chipset in an adapter without changing its model number. Check your store's return policy before purchasing, caveat emptor.

For example, D-Link has an annoying tendency to silently replace the chipset in their models without changing the model name. This means that even if a particular model is known to be compatible, this might not apply to the unit you have acquired.

Unconfirmed devices

In theory, these devices should be compatible--please confirm that they are working:

• D-Link DUN-E100 - please confirm that this is working

[ 3/15/2008 - I can confirm that D-Link DUB-E100 (both V. A3 and A1) worked fine right out of the box with Builds 656 & 650; no reboot needed. (I'm not sure there was a model DUN-E100; I could not find reference to it on D-Link's web site.)]

Device support implied by driver source code

Bert asked (on 09:47, 24 August 2006): Wouldn't the driver sources (drivers/net/usb/asix.c) be the ultimate reference to what is supported?

This should be the case, but unfortunately is not. Many manufacturers and merchants do not coordinate with the driver maintainers, so the source code lacks the information needed to be the "ultimate reference". For example, see the warnings above about D-Link changing chipsets without notice. Nonetheless, the source code has valuable information as follows:

awk '/products/{if(p)exit;p=1};/^.\/\//{if(p)print}'
drivers/usb/net/asix.c | sed 's|.*//|*|'

• Linksys USB200M
• Netgear FA120
• DLink DUB-E100
• Intellinet, ST Lab USB Ethernet
• Hawking UF200, TrendNet TU2-ET100
• Billionton Systems, USB2AR
• ATEN UC210T
• Buffalo LUA-U2-KTX
• Sitecom LN-029 "USB 2.0 10/100 Ethernet adapter"
• corega FEther USB2-TX
• Surecom EP-1427X-2
• goodway corp usb gwusb2e
• ASIX AX/100
• ASIX AX/100/1000
• Linksys USB200M Rev 2
• 0Q0 cable ethernet

And this is only for the AX8817X chipset, there are many more drivers in drivers/usb/net/. In a current kernel config, all of them are enabled (see boot/config-2.6.17-1.2584.olpc1).

Maybe ether.c is helpful too? -- ??, 2007-12-20

Run ifconfig to see it working

In Terminal Activity, you can enter

/sbin/ifconfig

and see what is and isn't working in networking. (Thanks to ektoric in the forum for the path explanation http://en.forum.laptop.org/viewtopic.php?f=1329&t=151544)
