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.
Cheers
Andy M

# 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 you have got to here, the two DNS servers are unreachable
