I am using Ubuntu Linux v.2.6.16.5
My Wireless Adaptor is "Veritech VAC2511-D IEEE 802.11b complient",
its a Intersil Prism 2.5 Chipset.

Now i will explain you in detail. My email may go very long:

When i restart my machine with this card inserted it is automatically
loaded with orinoco_cs driver.
The output of iwconfig shows:
eth0      IEEE 802.11b  ESSID:""  Nickname:"Prism  I"
          Mode:Managed  Access Point: 00:00:00:00:00:00   Bit Rate:11 Mb/s
          Sensitivity:1/3
          Retry min limit:8   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=0/92  Signal level=-68 dBm  Noise level=-122 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

When i check the driver it shows:
fawad at Ubuntu-01:~$ ls -al /sys/class/net/eth0/device/driver
lrwxrwxrwx  1 root root 0 2006-05-17 09:11
/sys/class/net/eth0/device/driver ->
../../../../../bus/pcmcia/drivers/orinoco_cs

Now, i unload unload orinoco_cs driver and load hostap_cs driver. Then
insert the card again:
Now iwconfig shows:

Warning: Driver for device wifi0 has been compiled with version 19
of Wireless Extension, while this program supports up to version 18.
Some things may be broken...

wifi0     IEEE 802.11b  ESSID:"test"
          Mode:Master  Access Point: 00:00:00:00:00:00   Bit Rate:11 Mb/s
          Sensitivity=1/3
          Retry min limit:8   RTS thr:off   Fragment thr:off
          Power Management:off

wlan0     IEEE 802.11b  ESSID:"test"
          Mode:Master  Access Point: 00:00:00:00:00:00   Bit Rate:11 Mb/s
          Sensitivity=1/3
          Retry min limit:8   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

And the driver is also correct:

lrwxrwxrwx  1 root root 0 2006-05-17 09:14
/sys/class/net/wlan0/device/driver ->
../../../../../bus/pcmcia/drivers/hostap_cs

Now the problem is:

The output of dmesg:

There are few errors in the last few lines of the dmesg output. This
is because, when ever i insert my card again, the orinoco_cs drivers
are also automatically loaded i dont know how/why (I unloaded then
before i insert the card, but still they get loaded automatically when
i insert the card)?

I personally think, this is why i am getting some errors in the above
command. As you can also see these following lines  in dmesg output;

[4295823.045000] orinoco 0.15rc3 (David Gibson
<hermes at gibson.dropbear.id.au>, Pavel Roskin <proski at gnu.org>, et al)
[4295823.054000] orinoco_cs 0.15rc3 (David Gibson
<hermes at gibson.dropbear.id.au>, Pavel Roskin <proski at gnu.org>, et al)
[4295823.060000] pcmcia: registering new device pcmcia0.1

I also tried to blacklist these drivers, as mentioned in my last
email. But still this does not work.

I will be thankful, if could please look how can i getrid of this
error in dmesg.
Now as you said i have sent a detail email. If you need any more
information please let me know.

Best Regards,
Fawad.
