New driver for Zydas 1211 wifi adapter: please help me !

I own an Inexq uro55g (zydas 1211 chipset) ; Zydas has released this driver: http://www.zydas.com.tw/downloads/download-1211.asp . I modified Makefile to point to linux source /usr/src/linux-2.6.12 then I issued make , modprobe -v zd1211, and lsmod says me that the driver is installed (tried also insmod zd1211.ko). The problem is that if I type ifconfig I can see only my eth0 (realtek) and no eth1 comes up. How can I do ? (sorry if I did something wrong but this is the first time I try to install a linux driver)

tnx

ifconfig by itself will only list 'up' or configured devices.
Use 'ifconfig -a' to list all configured & unconfigured network devices and see if your device is listed.
