This project is focused in distributing a Linux driver for the ZyDAS 1201 based USB 802.11b Network adapters. Such as the Sweex LC100020 sold by Sweex Essentials and others.

Originaly sweex distributed a linux driver for its Wireless(802.11) USB adapters, but suddenly they retired their linux drivers from their support site, and according to their technical support linux was no longer supported for that product.
The driver was a modification on the linux-wlan-ng driver developed by AbsoluteValue Systems.
As the driver works and its released under the MPL and GPL license this project is going to publish the original driver, and any modifications people submit.

Later versions of the driver have been supplied by other Zydas 1201 manufacturers.

A new, much smaller, driver was later developped to overcome the problems of the wlan-ng driver.
Now it is part of the main kernel tree as of 2.6.12.
It is recommended that you try this driver instead of the old wlan-ng driver since all new development is done on this driver.

If you want to use the driver merged in the linux kernel tree you have here some brief instructions.

HELP!!! My device isn't accepting its address when I plug it in!!

This is a known problem... The devices do not implement the USB specification correctly. There is a difference in enumeration between Linux and Windows (both methods are valid according to the USB specification). With the driver a patch to the USB stack is supplied for various kernels. Also as of 2.6.10-rc2 this problem should be fixed.
