    What is the output of which mdev? According to the BusyBox documentation, mdev is in /bin and not /sbin.

    Assuming that mdev is correctly activated, can you verify that hotplug is configured in the kernel you are using? It would be the CONFIG_HOTPLUG line in the kernel’s configuration file. You may be able to check /proc/config.gz* depending on the kernel’s configuration.

    Assuming that mdev is correctly activated and hotplug is enabled in the kernel, your problem may be in mdev’s configuration file /etc/mdev.conf.

    Another thing that may be helpful would be setting /proc/sys/kernel/hotplug to a shell script that logs the environment and command line it is invoked with.

    #!/bin/sh
echo $* >> /tmp/hotplug.log
env >> /tmp/hotplug.log
