TP-Link wireless usb (zd1211)

[Nuno Magalhães <nunomagalhaes@eu.ipp.pt>]

Greets,

i'm trying to setup wireless through a USB adapter. I haven't quite
managed it although it seems its firmware is supported. This is what
i've tried so far:

It's a TP-Link TL-WN322G, i've installed these packages:
wireless-tools wpasupplicant wicd iw lshw lsusb

I've modprobed zd1211rw into /etc/modules, it now has:
loop
sbp2
/etc/modules
...and i probed it to try and activate it.

There's /lib/firmware/zd1211 with a bunch of files

# lsusb
Bus 001 Device 003: ID 15ca:00c3 Textech International Ltd. Mini Optical Mouse
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 007: ID 0ace:1215 ZyDAS WLA-54L WiFi
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hu

# lshw -C network
 *-network
       info on my eth1 (eth0 is firewire)
 *-network DISABLED
      description: Wireless interface
      physical id: 1
      logical name: wlan0
      serial: <MAC-adress here>
      capabilities: ethernet physical wireless
      configuration: broadcast=yes multicast=yes wireless=IEEE 802.1

I've tried this in /etc/network/interfaces:
allow-hotplug wlan0
iface wlan0 inet dhcp
       essid "my ssid here"
       mode Managed #also tried Auto
       freq 7
       key s:mykeyhere

Also tried wireless-{essid,...}, nothing works:

# ifup wlan0
Error for wireless request "Set Encode" (8B2A) :
   SET failed on device wlan0 ; Invalid argument.

wmaster0: unknown hardware address type 801
SIOCSIFFLAGS: Connection timed out
SIOCSIFFLAGS: Connection timed out
wmaster0: unknown hardware address type 801

..then it tries do get IP but obviously fails

The driver is there - i think -, the usb device is found... but it
gets no wireless. Somehow it's disabled... I use WPA in my LAN but
this laptop's going to another LAN (not sure about the config). Is
there a way to configure it through ifconfig? Or, better yet, some GUI
i can use?



On reboot a usb device was consecutively found on address 2, 3, 4, 5...
# dmesg |grep usb

Wicd finds no wireless networks. Now lsusb hangs and lshw only shows eth1

Any suggestions?
TIA,
