OK, just for the record let's clear up some misinformation.
mdev -s is needed to seed mdev with the devices existing when the kernel boots
so that they get processed according to the rules set up for mdev.
echo ....> /proc/sys/kernel/hotplug is ONLY required if the correct value is
not configured into the kernel.
busybox installs mdev at /sbin/mdev , that is what I set it to.
What seems to have been preventing the hotplug mechanism firing mdev is my case
was a kernel config error.
CONFIG_UEVENT_HELPER_PATH=/sbin/mdev , OK
The following also need to be set: CONFIG_HOTPLUG, CONFIG_PROC_SYSCTL
CONFIG_SYSFS CONFIG_CONFIGFS_FS
My problem was that CONFIG_CONFIGFS_FS was M and not Y. A minor slip up with
long reaching effects.
It took me a while to find since I was incorrectly seeing this as mdev problem
rather than a kernel problem.
Once that was sussed it was trivial to get the authentication with the AP
working and the rt73 driver works beautifully despite the figures looking a bit
low.
Quality=30/70 Signal level=-80 dBm
Dlink G122 would seem to have been good choice for this use.
