prism2_config() failed... (Consulted FAQ's and Mailing archive but still could not resolve)

[Fawad Nazir]

Hi All,

I am using Ubuntu 5.10 linux v.2.6.16.6 and hostap v0.4.4 (that comes
with the kernel).
After loading this driver i inserted my PCMCIA card (Veritech
VAC2511-D Intersil Prism Chipset 802.11b complient), everything was
going ok. I checked the output of dmesg and it was:

fawad at Ubuntu-01:~$ dmesg

After looking at FAQ's and maling archive i again reloaded the driver
with ignore_cis_vcc=1.

fawad at Ubuntu-01:~$ sudo modprobe hostap_cs ignore_cis_vcc=1
WARNING: /etc/modprobe.d/my_blacklist line 1: ignoring bad line
starting with 'orinoco_cs'
WARNING: /etc/modprobe.d/my_blacklist line 2: ignoring bad line
starting with 'orinoco'

Then i was able to get rid of Vcc mismatch - skipping entry.

My dmesg now is:

Still i was able to get rid of few errors in the end of the above output.

I have few questions:
1. Why am i getting the above errors and how can i resolve these errors?
2. In the FAQ-1 it says : "This can be enabled by setting
ignore_cis_vcc=1 in /etc/pcmcia/hostap_cs.conf". But i can not find
/etc/pcmcia/hostap_cs.conf file, should i create a new one?
3. Why the out of dmesg shows the following messages. Is orinoco
driver also being tried to load:
[4296860.095000] orinoco 0.15rc3 (David Gibson
<hermes at gibson.dropbear.id.au>, Pavel Roskin <proski at gnu.org>, et al)
[4296860.123000] orinoco_cs 0.15rc3 (David Gibson
<hermes at gibson.dropbear.id.au>, Pavel Roskin <proski at gnu.org>, et al)
[4296860.127000] pcmcia: registering new device pcmcia0.1

I have already blacklisted it. But still it is listed in lsmod command.

I will be thankful for your help.

Best Regards,
