In my work to bring sanity to basic networking I explored this. For 2008.x
the solution I ended with was udev. Two files in my netfix tarball pertain
to this:
#/etc/udev/rules.d/usbnet
subsystem=="power_supply", RUN+="/etc/udev/scripts/usbnet.sh"
#/etc/udev/scripts/usbnet.sh
#!/bin/sh
# when USB is plugged/unplugged in device mode, udev triggers this script
on power change
# udevd does clearenv(). Export shell PATH to children.
export PATH
if [[ $(cat /sys/devices/platform/s3c2410-ohci/usb_mode) = "device" ]]
then
if [[ $(cat
/sys/devices/platform/s3c2440-i2c/i2c-adapter/i2c-0/0-0073/chgmode) =
"play-only" ]]
then
ifdown usb0
else
ifup usb0
sleep 5
if [[ $(ping -c2 -q $(ip r | grep usb0 | grep default | cut -d' ' -f3) |
grep loss | cut -d' ' -f4) = 0 ]]
then
ifdown usb0
fi
fi
fi
The only problem with this approach so far is that on powerup it doesn't
trigger, only on USB insertion after fully booted.
