Installation

1. Check if zd1201 module is already loaded by typing the following command in a terminal:

sudo lsmod | grep zd1201

Output should be something like:

zd1201                 22660  0
usbcore               130692  4 zd1201,ehci_hcd,uhci_hcd

If the output is empty you have to load the module by the following: type uname -r, the output shows your kernel version. Now you have to edit (sudo gedit <filename> or some editor of your choice as root) the following three files:

/lib/modules/VERSION_OUTPUT_OF_COMMAND_ABOVE/modules.alias
/lib/modules/VERSION_OUTPUT_OF_COMMAND_ABOVE/modules.dep
/lib/modules/VERSION_OUTPUT_OF_COMMAND_ABOVE/modules.usbmap

Replace VERSION_OUTPUT_OF_COMMAND_ABOVE with the output of the uname -r command. In your editor add

zd1201

at the bottom of the file, if the phrase isn't in there yet.

1. Now download the 1201 Firmware from Sourceforge.net, unpack (tar -xzvf) zd1201-<version>-fw.tar.gz to /tmp and change working directory via cd /tmp/zd1201-<version>-fw.
2. Last but not least you have to copy the firmware files to /lib/firmware by

sudo cp -p -f zd1201*.fw /lib/firmware

Now plugin your WLAn adapter. iwconfig should list the adapter in it's output.
