The openbsd code is found at:
http://www.openbsd.org/cgi-bin/cvsweb/src/sys/dev/usb/if_zyd.c
and a derivitive work of that is found the subversion repo:
http://svn9.cvsdude.com/kdesolaris/zyd/trunk
I used the openbsd code to extend the original zyd-0.1 code for open solaris
that was done the by the students at Charles University in Prague, to add
zd1211b support, as well as several other radios and chipsets.
