I set this up in a startup script on a 7350 that is based on the original TS
script. The original script has a line mdev -s. I think a simple mdev
invocation just runs the population once so unless your device is always
plugged in when you power up, it won't be seen later. The busybox docs say to
do the echo line to "connect" mdev to the hotplug system.
This is working fine for me to hotplug a USB LCD display device. The one
caveat I see is that mdev/hotplug/usb takes 4-6 seconds to fully populate /dev
on startup once you reach the shell prompt. That kinda sucks but that's a
linux thing not a TS thing. My app needs to talk to a USB device when it
starts so I need to sleep my startup script before I launch my app.
I also went through the hassle of getting inotify working so that my app will
get an event when I plug in my USB LCD display but even that takes a couple of
seconds to register so whether or not using inotify is better than polling for
the device is debatable.
