After a really rocky start, all's well to move on except for my wireless
networking devices. I have two: an internal wireless card, which I want
to be the work-horse, and a usb device. On boot, the kernel recognizes
them, the modules are loaded and they are named--wlan0 and wlan1,
respectively. The light indicating that the wireless card is powered
comes on. However, <ls /dev | grep wlan> gives no output. <udevadm
info --query=all --name=/dev/wlan0> returns "device node not found."
Same for wlan1. <ip link wlan0> fails also. I'm stumped.
<dmesg> and <lsmod> tell me that everything is recognized, it seems that
the devices are not being created. Below is info from <udevadm info
--attribute-walk --name=/sys/class/net/wlan{0,1} and the rule for each
from 70-persistent-net-rules.

I need to mention that in /sys/bus/pci there is another name--phy0.
It's the parent of wlan0. The rules got generated by <udevadm test>.
Can anyone see anything that I'm missing. At this point is has to be
something really simple and I can't see the tree because of the
forrest. Just a thought. Although the udev system is much more
complicated now than when I did my last LFS build, I know that I can
change the ATTRIBUTE(s) of a device. (I'll have to read up on it to
refresh my memory.) Is something like that necessary here.
I'll appreciate any advice, thoughts or "try this."
BTW. Using SVN-20090922-x86-Multilib
Thanks,
Dan
