<DIV>Hello,</DIV>
<DIV> </DIV>
<DIV>You could check raspberrypi.org:- <A
href="http://www.raspberrypi.org/">http://www.raspberrypi.org/</A></DIV>
<DIV>Click on Forum, and in the search box 'stakis3g', lots of hits.</DIV>
<DIV>As you are getting random crashes and have a 2A power supply, its still
possible the voltage is down, under load.</DIV>
<DIV>Check the voltage on the Pi, TP1 to TP2, try it with nothing plugged in
except the power supply, plug things</DIV>
<DIV>in one at a time, check the voltage. Are you overclocking? Check the
voltage under heavy CPU load.</DIV>
<DIV>Does your powered hub backfeed power to the Pi?</DIV>
<DIV>I'm using a 5.25V - 2A power supply, after it gets to the Pi through the
cables and connectors. it drops to</DIV>
<DIV>5.1V and under load to 5.06V (I'm overclocking to 1Ghz) and a 7 port hub
with a 3A power supply.</DIV>
<DIV>About 4.85V TPI to TP2 is a working minimum under load.</DIV>
<DIV> </DIV>
<DIV>Regards</DIV>

Afternoon,<BR>I'm working on an HNC assignment using a Raspberry Pi model B
running<BR>wheezy-raspian.<BR>I'm a Linux Novice.<BR>The Kernel
is:<BR>pi@raspberrypi /usr/bin/modem3g $ cat /proc/version<BR>Linux version
3.6.11+ (dc4@dc4-arm-01) (gcc version 4.7.2 20120731<BR>(prerelease)
(crosstool-NG linaro-1.13.1+bzr2458 - Linaro GCC 2012.08) )<BR>#538 PREEMPT
Fri Aug 30 20:42:08 BST 2013<BR><BR>I have been using sakis3g and ser2net to
connect the RPi to the cellular<BR>network and act as a serial terminal
server. (based on various posts and<BR>blogs)<BR>I have added the following to
rc.local in an attempt to connect to the<BR>mobile network and configure the
serial terminal server.<BR>****<BR>#!/bin/sh -e<BR>#<BR># rc.local<BR>#<BR>#
This script is executed at the end of each multiuser runlevel.<BR># Make sure
that the script will "exit 0" on success or any other<BR># value on
error.<BR>#<BR># In order to enable or disable this script just change the
execution<BR># bits.<BR>#<BR># By default this script does nothing.<BR><BR>#
Print the IP address<BR>_IP=$(hostname -I) || true<BR>if [ "$_IP" ];
then<BR> printf "My IP address is %s\n" "$_IP"<BR>fi<BR><BR>(sleep
2;sudo /usr/local/sbin/ser2net -c /etc/ser2net.conf -n) &<BR>#sudo
/usr/bin/modem3g/sakis3g connect<BR>(sleep 5;sudo /home/pi/connect.sh)

APN_USER='user' APN_PASS='password' USBDRIVER=option<BR>USBMODEM=12d1:1003
OTHER=USBMODEM MODEM=OTHER<BR>****<BR>This normally works from a power on but
often doesn't from a reboot.<BR>I would like to debug the boot sequence to try
and make this more reliable<BR>however I'm not sure how to enable/capture the
debug output, I can't see<BR>anything in /var/logs.<BR>Is there any debug I
can enable or re-direct the console output to a file ?<BR><BR>I have found
that the 3g modem is not always listed in lsusb.<BR><BR>I also experience
random hangs/crashes and a power cycle is required to<BR>recover. I'm not sure
if this is hardware related. I have a 2A power adapter<BR>and a powered USB
hub that has the 3g modem, wifi adapter, mouse and<BR>keyboard connected to
it. The RPi will run for varying lengths of time.<BR>Any debug help would be
much appreciated.<BR>Best
