Thanks to the USB Host mode it's possible to setup and utilize a wired network connection for those times when you want to use your IT but don't have access to wifi (or there just isn't any wifi around to use). A good example of this type of scenario is in hotel rooms while traveling around; most have wired high speed connections in the rooms but don't offer any kind of wifi connectivity. Although it's possible to carry around a small wifi router, it can be a bit more cost effective and convenient to connect the tablet to the wired connection directly.

With [[USB host]] mode it's possible to setup and utilize a wired network connection for times when you don't have access to WiFi (e.g., hotel rooms). Although it's possible to carry around a small WiFi router, it's frequently more cost effective and convenient to connect the tablet to the wired connection directly.
-
In order to do this you need to make sure that you have USB Host mode up and working properly (whether via cable or software switch; see the [[HOWTO: USB Host mode on the N800 using OS 2008]] entry for details). OS 2008 natively supports USB adapters based upon the RTL8150 chipset such as the Linksys USB100M; however it's possible to find other devices that are supported by custom compiled modules.

This is also an important consideration regarding the type of network adapter you select to use. The Linksys USB100M for example is only listed as USB 1.1, not 2.0, but still functions above the maximum sustainable speed of the tablet. Conversely, while the 2.0 version of the same device should work, it required additional drivers and actually requests more power than the USB OTG chip in the Tablet is willing to provide, so you'd end up needing an externally powered USB hub to use it. Thus while the USB 2.0 adapter might seem better, in actually for the ITs it's a worse choice.

Revision as of 16:11, 12 May 2009

With USB host mode it's possible to setup and utilize a wired network connection for times when you don't have access to WiFi (e.g., hotel rooms). Although it's possible to carry around a small WiFi router, it's frequently more cost effective and convenient to connect the tablet to the wired connection directly.

Contents

Pre-requisites

In order to do use a USB ethernet adaptor, you'll need to make sure that you have USB host mode up and working properly (with an OTG cable or a software switch). OS2008 natively supports USB adapters based upon the RTL8150 chipset such as the Linksys USB100M; however it's possible to find other devices that are supported by custom compiled modules.

If you're looking for a "ready to go" solution simply pick up a supported USB100M along with your USB OTG adapter.

Setup

Once you've got some compatible hardware ready to go, the easiest step is to next install the USB LAN package. The updated version of the package utilizes the dbus-scripts package, which can also be easily installed by following this.

The package will setup a few scripts and install all of the additional USB LAN drivers that are available for the OS: 

catc.ko
dm9601.ko
kaweth.ko
mcs7830.ko
pegasus.ko
rt73.ko (Added in 0.4.6 for external USB Wifi adapters)

Note: anyone who knows of other commonly supported and tested working devices using these drivers, please add them to the end of this entry.

Step by step

  1. Install the dbus-scripts package.
  2. Install [http://www.electronicproductonline.com/~electron/catalog/supportFiles/usbLAN_0.4.6_armel.deb USB LAN package.

Once the packages are installed any RTL8150 device will operate as follows:

  1. Connect USB device to LAN cabling.
  2. Connect USB device to the tablet.
  3. Wait for the USB messages to popup ("USB Device Not Supported", "No Filesystem Found").
  4. Launch your web browser or whatever application you want to use.
  5. Surf and enjoy.

For devices other than those based on the RTL8150 you'll manually need to call usbEthUp.sh after you connect your device, and usbEthDown.sh after you remove it to get the network settings in place. These scrips can be found in /usr/sbin.

When you're done with your wired connection simply unplug the network adapter from the USB host cable (this lets the tablet recognize that the adapter has been unplugged), then disconnect your host cable from the tablet (and manually set it out of host mode if required). Also, don't forget to choose "Disconnect" from the connection window (click on the little WiFi icon), or your tablet will try to stay connected to "WIRED" until you restart or manually force a new connection.

Performance

Do not expect a wired connection to help you gain faster transfer speeds. In testing, it has been found that the CPU on the tablet maxes out at approximate 5-7Mbps, well beneath the threshold of wired networks or USB connectivity.

There is also an important consideration regarding the type of network adapter you select to use. The Linksys USB100M for example is only listed as USB 1.1, not USB 2.0, but still functions above the maximum sustainable speed of the tablet. Conversely, while the USB 2.0 version of the same device should work, it required additional drivers and actually requests more power than the USB OTG bus on the tablet is willing to provide, so you'd end up needing an externally powered USB hub to use it. Thus while the USB 2.0 adapter might seem better, in actually for the tablets it's actually a worse choice.

Tested Devices

How to test:

  1. Make sure you have the latest driver and scripts installed as noted above. You will also need root access installed.
  2. Open XTerm.
  3. Connect your USB adapters (including OTG adapter if you are using that product).
  4. Connect your USB ethernet device.
  5. You will see error messages that can be ignored.
  6. Run sudo becomeroot in XTerm.
  7. Run /usr/sbin/usbEthUp.sh.
  8. Note messages. A successful connection will be indicated by an acquired IP address (<cod>Lease xxx.xxx.xxx.xxx obtained</code>, where xxx represents parts of an IP address).
  9. Run dmesg.
  10. Scroll up through messages until you discover text describing the ethernet adapter, containing codes prefixed by v (vendor code) and p (product code). The characters following v and p will be entered into the appropriate fields as shown below.
  11. Any unknown information should be added after the corresponding field as Unknown.

The following USB ethernet devices have been tested:
