README for zd1201 Wireless USB driver.

The zd1201 driver works with USB Wireless devices that use the ZyDAS ZD1201
chip.
Unfortunatly this device doesn't completly follow the USB spec and needs a patch
to the linux usb core. This patch shouldn't interfere with other devices but
if it does please send a message to me.

Go into your kernel source directory (e.g. /usr/src/linux-2.6.7/) and execute
the following command:

	patch -p1 <zd1201-0.7/2.6.7-usb-broken-descriptor.diff

(Don't forget to fill in the correct path to the diff file.)
It is wise to do a dry run first:

	patch -p1 --dry-run <zd1201-0.7/2.6.7-usb-broken-descriptor.diff

This way you can try each of the different patches first to see which version
you need.

Now rebuild your kernel and install it or if you have the usb subsystem as
modules rebuild the modules and install them.

Recent 2.6.10-rc kernels should work with this device without patching.


Building the zd1201 driver is easier, simply go into the zd1201-0.7 dir and type

	make

Followed by

	make install

You will have to install a seperate package with firmware files before the
driver will work properly. Look at http://linux-lc100020.sourceforge.net/

After pluging in the zd1201 device and loading the driver you should get a new
wlan device.
Try:

	iwconfig

which should show you all wireless devices.

Please send questions to the sourceforge forum (in case of problems add 'dmesg'
output) at http://linux-lc100020.sourceforge.net/
