E169G Switch is a package for Ubuntu and other Debian based distributions, such as Xandros on the Asus EEE that aims to autoconfigure the device when it is plugged into the machine. These modems act as a USB drive until a command is sent to them to be a modem. This package makes sure that gets sent.
If you own an Asus EEE PC or another machine running Ubuntu and a camera which is only supported under Video4Linux 2 (V4L2) you will have noticed that it not possible to get your camera to work under Flash. This will hopefully change soon, with V4L2 support in Flash 10. However, as Flash 10 is still a release candidate you might find that you still have problems when using a V4L2 camera.
