I'm having real difficulty setting up WLAN connectivity in Linux on my
new ECS Desknote, and I'd love some help. The device is an AirVast
PRISM3 card, internally connected on a hidden USB bus. The VID/PID are
included in the current version of linux-wlan-ng, so I guess it's
supposed to be supported. This is a bit of a multifaceted problem -
this is my first serious non-experimental attempt to use 2.6 kernels,
and I'm not fully aware of the differences between FC1 and FC2. I'm
using kernel 2.6.8.1.

Historically I've had no difficulty getting linux-wlan-ng to play nice
with kernel 2.4.x on my older laptops with external USB pods. But I
don't know if it's the device or the kernel or something I've
forgotten in the config process; if someone could read over these
looking for obvious errors it would be MUCH appreciated.

Here's my ifcfg-wlan0 (no my key is not 8888... :):

DEVICE=wlan0
BOOTPROTO=dhcp
ONBOOT=no
TYPE=Wireless
ESSID=LARWE
CHANNEL=11
MODE=Managed
RATE=Auto
KEY=88888888888888888888888888

Here's my /etc/wlan/wlan.conf:

WLAN_DEVICES="wlan0"
ChannelList="0b:06:01:02:03:04:05:07:08:09:0a:00:0 0:00"
ChannelMinTime=200
ChannelMaxTime=250
WLAN_SCAN=y
SSID_wlan0="LARWE"
ENABLE_wlan0=y


Here's my /etc/wlan/wlancfg-LARWE:

lnxreq_hostWEPEncrypt=true # true|false
lnxreq_hostWEPDecrypt=true # true|false
dot11PrivacyInvoked=true # true|false
dot11WEPDefaultKeyID=0 # 0|1|2|3
dot11ExcludeUnencrypted=false # true|false, in AP this means WEP is
required.
dot11WEPDefaultKey0= 88:88:88:88:88:88:88:88:88:88:88:88:88
dot11WEPDefaultKey1= # xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx
dot11WEPDefaultKey2= # e.g. 01:20:03:40:05 or
dot11WEPDefaultKey3= # 01:02:03:04:05:06:07:08:09:0a:0b:0c:0d
IS_ADHOC=n # y|n, y - adhoc, n - infrastructure
AuthType="sharedkey" # opensystem | sharedkey (requires WEP)
BCNINT=100 # Beacon interval (in Kus)
CHANNEL=11 # DS channel for BSS (1-14, depends
# on regulatory domain)
BASICRATES="2 4" # Rates for mgmt&ctl frames (in 500Kb/s)
OPRATES="2 4 11 22" # Supported rates in BSS (in 500Kb/s)


Now, here's a snippet of dmesg when the USB driver is loading and I
attempt ifup wlan0:
