hi moustique/peibl,
I've looked at your logs, but they don't tell me much I'm sorry to say.

Perhaps you can try my current setup. I've using Zorander's ext3-0.9.2 package with my updated wireless-mod... ->
http://www.mediafire.com/file/rzdydjcyetj/wireless-mod.app-rt2870.zipUnzip to the root of your usb key. You should have the following files:
/RT2870STA.dat
/wireless-mod.app.bin
/<your wpa_supplicant.conf>
/wpa/wpa_cli
/wpa/wpa_passphrase
/wpa/wpa_supplicant
and add the following to your net.config
HOST=wdtv
/boot/wpa/wpa_supplicant -B -Dralink -i$MDEV -c/boot/wpa_supplicant.conf
DHCP=yes
This uses the latest ralink drivers (v2.1.1.0) and wpa_supplicant (v0.6.9). I couldn't get the current version to work with my WPA2/AES setup.
Good luck!
note: this is the full list of devices supported in this driver:
