I've done some digging around, and it looks like your zd.o and zd_b.o are 
incompatible.

Using your zd.o, the insmod succeeds buts ifconfig wlan0 does not - no such 
device or 
address.

Using insmod zd_b.o on its own is much more profitable and yields loads of 
output in 
dmesg:

ZD1211B - http://zd1211.ath.cx/ - r83

zd1205: (exit) zd1205_open, src/zd1205.c line 4436

After this, ifconfig wlan0 up succeeds.

In the Techologic FTP server, there are four, count 'em, version of zd.o in the 
directory ts-
modules:
Name   Size     MD5sum
zd-r51.o        263206  7e1340aa0d79db6ee6b247037ab46cad
zd-r83-b.o      312644  ea5d1c980a6de67caac2a3fe4935fce5
zd-r83.o        311436  067fe55699354f526e5f680a3139a109
zd.o    299666  75cbd70e73d5704db17c8d269bae37df

The one called zd-r83-b.o has the same md5sum as your zd_b.o.

The zd-t51 contains strings like kernel-version: 2.4.26-ts9, so should be 
avoided.

Whoever, I am still stumped as for what to do after 'iwconfig wlan0'.  I can't 
find any 
instructions or howtos.  Obviously I would like to have the inteface configured 
at boot 
time.

Do I need to do iwconfig wlan0 essid MYESSID?
Do I need to do iwconfig wlan0 ap xx:xx:xx:xx:xx?

I get results from iwscan:

$ /usr/local/bin/iwlist wlan0 scan
wlan0     Scan completed :
          Cell 01 - Address: 00:18:4D:3F:87:72

$ 

But still show Not Associated:

          Tx excessive retries:21320  Invalid misc:855   Missed beacon:0

even after doing iwconfig wlano ap xx:xx:xx:xx:xx

Thank,

Martin
