Alright we have made changes that gave new udev monitor response see bellow... but still no glorry

what I did

1. Checked tha ACX howto and found that there was no mention of the missing firmware mentioned in UDEV

FIRMWARE=tiacx100c0D

2. Googled the firmware and found that there has been a change in naming conventions. Found this page
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/22238

saying that the missing firmware is renamed from RADIO11.bin so I went a got it from here

ftp://ftp.dlink.com/Wireless/dwl520+/Driver/dwl520+_drivers_307.zip <ftp://ftp.dlink.com/Wireless/dwl520+/Driver/dwl520+_drivers_307.zip> and creating the necessary file tiacx100c0D from RADIO11.BIN(from this package).

3. Then when I pluged in the card again the computer crashed
4. rebooted with pcmcia card out and logged in
5. plugged card in
6. results of dmesg (what's up with the kernel bug?)

The bellow output is what udev monitor --env spits back when I plug in my PCMCIA card (which essentialy loads the module at the same time). I really need to learn more about udev, cause it is a big black box.
You get this event:
UEVENT[1176480087.807781] add@/class/firmware/0000:02:00.0 ACTION�d
DEVPATH=/class/firmware/0000:02:00.0 SUBSYSTEM=firmware
SEQNUM37
FIRMWARE=tiacx100c0D
Do you have that file on your box?:
/lib/firmware/tiacx100c0D
Quoted 7 lines
Furthermore I don't wish to complicate matters but I notice that it creates device wlan0.. is there a way to make it create a ethX device. I know its a wireless device so that is convention, but the application i am trying to get going (kismet) thinks that acx will mount as a /dev/ethx. If its an easy answer great, if not then lets focus on the firmware first.

Most distros create persistent network names, by writing rules for every discovered device and assing the same name after reboot. You would just need to edit the rules file and set a different name.
