Sagem xn720 usb wireless doesnt connect

[joker_med]

Opensuse seems to detect my usb wireless adapter Sagem xn-720s but I cannot connect with it!!
this is what iwconfig returns:
"

After I installed madwifi like listed on other similar threads I tried to connect with Wicd and discovered that Wicd (a Network Manager) detect wireless networks only when I unplug then replug my usb adapter, seconds after that networks disappear again.
The same thing with kwifi Manager and when scanning networks on Yast Wireless Network Manager.
I think somehow the device automatically shutdown after a certain period, but the led on the adapter still flash !
Anyone can help please!

does the output of the command 'dmesg' offer any clues?

I'm finnaly connected with my Sagem Xn-720s usb wireless adapter.

I had to download the "ar9170" package, here is the link:
