          The flash is a good thing.  That means the adapter is in fact 
transmitting.  The problem is that the adapter and the AP haven yet got 
the same configuration.  The basic elements that need to be the same are:
Chanel (actually needs to be Adapter = AP + 1),
SSID or ESSID, and
Encryption.
          In my configuration, SSID = default  and Enc = off.
          Also, what I could not remember last night.  I haven't seen 
Xubuntu, but in Ubuntu I went System-Administration-Networks (Ithink) 
and this allowed me to set IP address, netmask and gateway for the 
rausb0 interface, and more importantly, to set rausb0 as the default 
interface.
          I am using Dapper Ubuntu with a 2.6.15-28 kernel.  I 
originally tried Ndwrapper with the XP driver but had no luck  I then 
did a lot of googling and looked at the Serialmonkey's rt2x00 project 
and rt73 legacy drivers but ended up using the bog standard Ralink 
Technologies RT73 driver RT73_Linux_STA_Drv1.0.3.6.tar.gz.  This needs 
to be compiled against you kernel.  It produces a loadable kernel module 
rt73.ko, a configuration file rt73sta.dat, and a binary file rt73.bin.  
I came across an excellent step by step howto.  I cannot remember where 
I found it but I have a printed copy if you are ever interested, contact 
me off-list.
           Hope all this helps, but feel free to contact me on list or 
off list if you have questions.  I must admit I was ready to give it all 
away myself and then it just started working and I have'nt looked back 
since.  Still need to work on dhcp, encryption and WPA but at least it 
works.
