I just bought it and it works well with my Z 5500, SharpROM 3.10. All I have to do is to plug it in, setup a wireless network service on the Z with my Linksys BEFW11S4 (v2) SSID & WEP key, and it works. No driver installation required.
However, the IP and subnet mask assigned appear random with every connection, even though I set it up to use static IP. Not sure why, and interestingly enough, the connection works. A reboot took care of that.
Now the card is working perfectly normal, with correct IP.
Just thought I\'ll post it so that people who are thinking of getting a wireless CF have another choice.
