I've got the same card, and it works.

Here's my config (/etc/network/interfaces):

iface eth1 inet dhcp
        name Carte WiFi
        wireless_essid  (my essid)
        wireless_key    (my wep key)
        wireless_mode   Managed
        wireless_ap     any

It seems that you must call "iwconfig eth1 key on" after setting the key
if you do it manually.
Why do you try to set the WEP key as an ascii password ("s:"), and set
the security mode ("open").
I let the driver search for this settings and it works. If you don't put
the wireless settings in the interface file:

iwconfig eth1 key XXXXX...XXXX
iwconfig eth1 key on
ifup eth1

should be enough.
