Hi There,

A question I have had for years and to which I have found no answer is 
how do you reset the Speedtouch 330, without resorting to unplugging it 
and plugging it back in again. I have now found a way of doing this and 
have written a script to be run by cron that keeps the machine connected.

I have attached it below. I hope the commentary is sufficient to explain 
what is going on. It is release as GPL. If you have any fixes or 
improvements I would hope you would return them to me.

# This script works around the instability of the Speedtouch 330
# by checking for presence of a working Internet connection and
# if not present, puts the relevant USB port into hibernation
# and then brings it back out again, thus causing the firmware
# to be reloaded and the device rebooted.

# Check for live link by pinging two of the DNS root servers.
# The odds of both being down are pretty remote.

if ping -c 3 > /dev/null
        logger -t ADSL-cron "Connection OK"
        exit 0
        if ping -c 3 > /dev/null
                logger -t ADSL-cron "Connection OK"
                exit 0
                logger -t ADSL-cron "Connection DOWN"

# If you have got to here, the two DNS servers are unreachable
# which almost certainly means that the device has locked up
# and the link is down. So now look for the code 4061 in the
# USB devices products and note the DEV number.

for file in /sys/bus/usb/devices/*/idProduct
        if grep "^4061$" $file > /dev/null
                DEV=` expr $file : 
'/sys/bus/usb/devices/\([0-9][0-9\-]*\)/idProduct' `
                LEV=`cat /sys/bus/usb/devices/$DEV/power/level`

# Check that you've found the DEV number and if you did
# then pull down the ppp0 interface, hibernate and revive
# the USB port and then bring up ppp0.

if [ "$DEV" != "" ]
        logger -t ADSL-cron "Device: $DEV is $LEV"

        logger -t ADSL-cron "Dropping ppp0"

        ifdown ppp0

        logger -t ADSL-cron "Resetting USB Device"

        echo -n suspend > /sys/bus/usb/devices/$DEV/power/level

        sleep 3

        echo -n on > /sys/bus/usb/devices/$DEV/power/level

        logger -t ADSL-cron "Restarting ppp0"

        ifup ppp0
        logger -t ADSL-cron "Speedtouch 330 not found"
        exit 1
