The HUAWEI E1750 is sold under different names, some people report it as E220 or E1752. You should check in /proc/bus/usb/devices what is the vendor and product id of your 3G modem. You should see the following values:
vendor=0x12d1 product=0x1446

This howto should apply to all 3G USB modems with the same vendor and product id and any AP running OpenWRT Kamikaze 8.09.2.
Here is how I got the whole thing running:

1. Install the required kernel modules and utilities:


# opkg update
# opkg install kmod-usb-acm kmod-usb-core kmod-usb-ohci kmod-usb-serial comgt \
kmod-usb-serial-option kmod-usb-storage kmod-usb-uhci kmod-usb2 usb-modeswitch


2. Create or edit the file /etc/modules.d/60-usb-serial so that it only contains the following line:

usbserial vendor=0x12d1 product=0x1446

3. Create or edit the file/etc/usb_modeswitch.conf so that it looks as follows:

DefaultVendor= 0x12d1
DefaultProduct=0x1446
TargetVendor= 0x12d1
TargetProductList="1001,1406,140c,14ac"
CheckSuccess=20
MessageEndpoint=0×01
MessageContent="55534243123456780000000000000011060000000000000000000000000000"


4. Add the following section to /etc/config/network:

WARNING!!! Depending on the model of your 3G modem you may need to replace ttyUSB0 with ttyUSB1, ttyUSB2, etc. Check the output of “dmesg” to know which is the correct port. If you are unsure, find out by trial-and-error.

config 'interface' 'ppp0'
option 'ifname' 'ppp0'
option 'proto' '3g'
option 'device' '/dev/ttyUSB0'
option 'apn' 'YOURAPNHERE'
option 'pincode' 'YOURPINCODEHERE'

Replace YOURAPNHERE with the name of your APN (e.g. “tre.it” for H3G Italy) and YOURPINCODEHERE with the PIN code of your SIM.

WARNING!!! If you have disabled PIN code verification for your SIM, you can omit the pincode option but you’ll need to workaround a bug in /lib/network/3g.sh. Open /lib/network/3g.sh in your editor and comment out the following lines:

# PINCODE="$pincode" gcom -d "$device" -s /etc/gcom/setpin.gcom || {
# echo "$cfg(3g): Failed to set the PIN code."
# set_3g_led 0 0 0
# return 1
# }


5. Reboot your OpenWRT device.

6. Manually run the following commands and after a minute verify that your 3G connection is working:

usb_modeswitch
ifup ppp0


7. Add the following lines to the top of /etc/rc.local:

sleep 3
/usr/sbin/usb_modeswitch
sleep 3
/sbin/ifup ppp0

8. Log on the web interface of your OpenWRT device and click on Administration/Networks/Interfaces/ppp0 and add it to the WAN zone.

You may need to adjust the DNS settings manually.

Here is what I had to do to make the USB modem work with Fonera 2.0N:

• for some crazy reason, my 3G modem refuses to work on Fonera 2.0N if there are some SMS stored on it. Plug the 3G modem into your PC and remove any SMS you may have received. YMMV.
• upgrade your Fonera 2.0N to the latest 2.3.6.0 firmware, choosing the “developer” image. You need the developer version to ssh into your Fonera 2.0N.
• ssh into your Fonera 2.0N router.
• edit /etc/config/umtsd:

config 'umtsd' 'umtsd'
 option '_country' '_custom'
 option 'apn' 'replacewithyourapn'
config 'umtsdstate' 'umtsdstate'
config 'umtsdevice' 'option12D11465'
 option 'vendor' 'Huawei'
 option 'device' 'K3765'
 option 'data' '/dev/ttyUSB0'

 option 'cmd' '/dev/ttyUSB0'

• plug the HUAWEI K3765 into the Fonera 2.0N router
• wait a few seconds and then run:

  echo "0x12d1 0x1465" >/sys/bus/usb-serial/drivers/option1/new_id

Visit http://fonera/luci/fon_devices/fon_umts and check the status of your 3G modem.

If it still doesn’t work, you may have to follow the instructions provided by stex1967:

Create the file /etc/usb-modeswitch.conf with the following content:

DefaultVendor= 0x12d1
DefaultProduct= 0x1520
TargetVendor= 0x12d1
TargetProduct=0x1465
MessageContent="55534243123456780000000000000011060000000000000000000000000000"


Also create the file /etc/rc.d/k3765:


#!/bin/sh /etc/rc.common
START=90
usb_modeswitch
sec=2
sleep $sec
echo "0x12d1 0x1465" >/sys/bus/usb-serial/drivers/option1/new_id


Finally run:


chmod 755 /etc/init.d/k3765
/etc/init.d/k3765 enable


and reboot. Thumbs up!

An updated list of supported 3G USB modems is available at http://wiki.fon.com/wiki/3G_compatibility

There is no need to flash a new firmware on it, just uninstall the Vodafone Mobile Connect software and replace it with the standard one from HUAWEI: you will be able to configure the software to use any APN you like.

You’ll still experience a small glitch though, at least under MacOSX: everytime you plug the modem into the USB port, you will see a popup asking you to install Vodafone Mobile Connect.

There is a simple solution to this problem:

• find out the UUID of your USB stick: diskutil info /Volumes/Vodafone\ Mobile\ Broadband/ | grep UUID
• create a new entry for this disk in /etc/fstab with the noauto flag turned on:
  • open /etc/fstab in your favourite editor (create it if it doesn’t exist yet): sudo vi /etc/fstab
  • add a line like the following to /etc/fstab:
    UUID=A46AA80A-97B9-3B47-91A4-8128A9458A31 none hfs rw,noauto 0 0

Replace the UUID with your own UUID.

Thumbs up! Now unplug your USB stick and plug it again: no annoying popup this time!

Panasonic has released a new firmware for the Panasonic Lumix DMC-FT1 compact camera which is worse than the previous version. The previous version (1.1) is no longer available on Panasonic website, so I made it available for you on my website: FT1__110.zip

Long story:

I already talked about the Panasonic Lumix FT1 camera in another post, in short the strenghts of this camera are:

• ability to go under water
• HD quality movies (720p)
• optical zoom during movie recording
• no limit on movie length

It’s really worth its price. You can find many example videos made with this camera on YouTube. The latest firmware available from Panasonic is ver. 1.2 . The main difference with regards to ver 1.1 according to Panasonic website is an “improvement of battery detection for safety standards Panasonic uses” which seems cool until you dig around for a while and discover that this improvement actually means that “after this firmware update your Panasonic Digital Camera cannot be operated by unauthorised 3rd party batteries“.
Wait a second, and you call this an improvement? No, thanks. I’d rather keep the ability to use 3rd party batteries.

So the next thing you do is check what other improvements have been introduced in firmware 1.1 compared to 1.0, here they are:

• Capable of playing back AVCHD motion picture format (1,280 x 720 )
• The quality of viewing image(still image) is improved.

Don’t care too much about the former, but the latter looks quite important.

Right, next question is: where can I download firmware 1.1 ? Panasonic was such nice to remove it from their website, and force anybody who wants to fix the 2 issues listed above to upgrade to ver. 1.2 and (bonus!) lose the ability to use 3rd party batteries.

That’s not nice, Panasonic!

Fortunately for you, I had the luck to save a copy of firmware 1.1 while it was still available, here it is for your convenience: FT1__110.zip

Come Sbrandizzare Nokia E90 Communicator Tastiera tedesca.

Il problema nasce dal fatto che la Nokia distribuisce gli E90 in Europa orientale, Germania e Lussemburgo con la tastiera QWERTZ anzichè la classica QWERTY. I firmware di questi telefoni tipicamente includono un tris di lingue la cui composizione varia da Paese a Paese ma che ha come costante l’Inglese.
Se impostiamo il telefono per l’utilizzo in lingua inglese avremo i menu in Inglese, ma il layout della tastiera viene cambiato in QWERTY causando non pochi problemi, senza contare che il T9 userà il dizionario Inglese.
La soluzione è modificare il product code del proprio telefono in modo che Nokia Software Updater pensi che il telefono sia stato acquistato in un altro Paese e scelga di flasharlo con un firmware che abbia la lingua che ci interessa per menu e dizionario del T9 e allo stesso tempo anche il layout tastiera corretto: nel nostro caso stiamo cercando il firmware Svizzero, che è associato al product code 0544355.

In breve ecco come possiamo cambiare il product code del nostro telefono Nokia E90 e flasharlo con il firmware associato al nuovo product code:

1. Scaricare e installare Nemesis Service Suite da qui
2. Scaricare e installare Nokia Pc Suite da qui
3. Scaricare e installare Phone Software Update da qui
4. Aprire NSS (Nemesis)
5. Cliccare sul pulsante Scan for New Device (é quello sulla destra)
6. Cliccare sul pulsante Phone Info e poi cliccate su Read
7. Inserire il seguente codice su Product Code: 0544355
8. Inserire la spunta su Enable
9. Cliccare sul pulsante Write
10. Dopo aver terminato l’aggiornamento chiudere Nemesis
11. Aprire Phone Software Update e scegliere di aggiornare il firmware anche se l’ultima versione è già installata

La cosa mi incuriosiva e dopo alcuni indagini in diverse occasioni ho scoperto che per diversi motivi, gli apparati venivano utilizzati con alimentatori DC non originali, vuoi perchè l’originale si era rotto o vuoi perchè l’originale viene dall’estero e usa un ingresso diverso da quello del proprio Paese.

Nulla di male in tutto questo, se non fosse che nella scelta dell’alimentatore dell’apparato si era tenuto conto esclusivamente di avere un voltaggio identico all’originale e un amperaggio uguale o superiore.

Succede così che un ottimo telefono VoIP come il Polycom, collegato all’alimentatore di un rasoio elettrico (per fare un esempio) vada in continuo crash, perda la memoria, bruci il display a led (sempre per fare un esempio).

Questo articolo spiega estremamente bene come scegliere un alimentatore adatto al proprio apparato:

Selection of AC-DC Power Adapters Regulated vs Unregulated.

Per riassumere l’articolo: un alimentatore DC non stabilizzato con un output da 9 volt / 500 mAh ha in uscita 9 volt solo quando viene assorbita una corrente di mezzo Ampere. Se viene assorbito meno di mezzo Ampere, il voltaggio è molto più alto.

Se per esempio prendiamo un alimentatore non stabilizzato da 9 volt, lo colleghiamo alla presa di corrente di casa e misuriamo l’output senza mettere alcun carico sull’uscita, potremmo vedere sul nostro voltmetro un output anche di 14 volt.

Un alimentatore stabilizzato invece ha sempre lo stesso voltaggio in output, indipendentemente dalla corrente assorbita dal carico.

In conclusione ecco due regole d’oro da seguire quando si deve sostituire un alimentatore:

• se dobbiamo sostituire un alimentatore non stabilizzato possiamo scegliere o un alimentatore stabilizzato di uguale voltaggio e amperaggio uguale o superiore all’originale, o un alimentatore non stabilizzato di identico voltaggio e amperaggio.
• se dobbiamo sostituire un alimentatore stabilizzato dobbiamo usare un alimentatore stabilizzato di identico voltaggio e amperaggio uguale o superiore all’originale

Un voltmetro è sempre utile :)

Here is the quick ‘n’ dirt way:

1. Go to http://www.taniwha.org.uk/ and download the scripts for Motorola 3.5G (HSDPA) phones
2. Extract the archive somewhere in /tmp
3. Enter directory /Library/Modem Scripts/Generic GPRS.ccl/Contents/Resources
4. Rename Base Script.ccl to Base Script.ccl.bak
5. Copy the file Motorola HSDPA CID1 from /tmp to the current dir and rename it to Base Script.ccl
6. Follow the usual procedure to configure Internet access with GPRS/EDGE/UMTS/HDSPA, in short:
   • From the Bluetooth menu choose Set up Bluetooth Device
   • Put you Mobile phone in Find me mode (refer to your mobile user guide)
   • Follow the instructions on screen to pair your phone with your Mac
   • At the end, be sure to mark Access the Internet with your phone’s data connection and press Continue
   • Make the following selections: Phone Vendor Motorola, Phone Model GPRS (GSM/3G), username/password/APN as provided by your mobile operator, CID 1 .
   • That’s it! Choose Connect from the Internet Connection menu.

CPU

Dual core processor correctly recognized, frequency scaling works ok except after suspending to memory. When resuming, the second core runs always at the maximum frequency.

You can read the temperature of each core by loading the coretemp kernel module and run:

cat /sys/devices/platform/coretemp.?/temp1_input

Remember to add coretemp to /etc/modules .

RAM

Nothing to say here.

Graphic card

My laptop is equipped with a GeForce 8400M GS card.

Install nvidia-glx-new, nvidia-kernel-common, linux-restricted-modules .

Ubuntu recognized the GeForce without any intervention. 3D works perfectly (tested with armagetron).

Run nvidia-settings to tune the parameters of the graphic card.

strawks reports that users with Intel GM965 Graphic Card experience stability problems under Xorg (see https://bugs.freedesktop.org/show_bug.cgi?id=11847)The external VGA port is almost unusable: when you plug the power adapter, some fuzzy lines appear on the external VGA screen/projector. Thanks Dell for putting the power port next to the VGA port. In the beginning I thought my unit was the only defective one, but a quick search on Google showed up a lot of people who experience the same problem.

TBD: test HDMI output
Hard drive

Make sure the SATA controller in the BIOS is set to AHCI. Ubuntu has no problem to recognize the controller and the hard drive. I also decided to enable the ‘quiet mode’ for the hard drive in the BIOS at the price of some performance (or so the manual says). Output of hdparm -t -T /dev/sda:

/dev/sda:
Timing cached reads: 7276 MB in 1.99 seconds = 3648.61 MB/sec
Timing buffered disk reads: 160 MB in 3.02 seconds = 53.06 MB/sec

Touchpad

Works out of the box. Typical features found on Synaptics touchpad (i.e. scrolling, double tap) are enabled by default.

Wireless

My laptop is equipped with an Intel PRO/Wireless 3945ABG. It works by default with ipw3945 which is part of linux-ubuntu-modules-2.6.22-14-generic package. Driver is rock solid.

Packet injection is available through the experimental module ipwraw. This one allows raw packet Tx/Rx with the Intel 3945ABG adapter, it’s raw mode only and can’t be used for normal connections to the Internet. Somebody at http://homepages.tu-darmstadt.de/~p_larbig/wlan/ added wireless extensions to this driver and made it work with aircrack-ng.

Jester de Jong reports that his laptop is equipped with Intel PRO/Wireless 4965 AGN and it works out of the box too with Ubuntu 7.10, but not on N-speed. The maximum speed he can get so far is 54 Mbit/s. Apparently for now there is no driver for Linux that supports N-speed (300Mbit/s).

Ethernet

Supported by the tg3 kernel module. Works out of the box.

Firewire

Works.

Hot keys

Hot keys for changing the volume, reproducing media, ejecting dvd, changing brightness all work out of the box.

Sound

This laptop is equipped with an Intel HDA audio with a Sigmatel STAC9228 codec. Output works fine by default, but the integrated digital microphone does not.

A patch is available on Ubuntu’s bug tracking system and some nice guy at Ubuntu generated an unofficial kernel module which already contains the patch.

Download http://people.ubuntu.com/~rtg/linux-backports-modules-2.6.22-14-generic_2.6.22-14.11UNRELEASED_i386.deb and install it with:

dpkg -i ./linux-backports-modules-2.6.22-14-generic_2.6.22-14.11UNRELEASED_i386.deb

Reboot.

After installing the package open a shell as root and run alsamixer:

• Go under Digital Input Source and select Digital Mic 1 instead of Analog Inputs
• Press F4 to change the view to Capture, then crank up the volume of Capture 1, Capture 2 and Digital
• Press ESC to exit alsamixer

Webcam

If you have a WLED screen (like me), you get a 0.3mpx webcam. It works with all V4L2 compatible programs after installing latest linux-uvc. Here are the steps I followed:

• apt-get install build-essentials
• svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk linux-uvc
• cd linux-uvc
• make install
• modprobe uvcvideo
• Remember to add uvcvideo to /etc/modules

If you want to make video calls using Skype, you must install Skype 2.0 beta. Works perfectly for me.

Jester de Jong reports that this webcam worked out of the box for him with the uvcvideo driver included in Ubuntu 7.10.

Feedback on the 2mbpx webcam which ships with the CCFL screen is welcome.

Multiple card reader

Secure Digital cards can be accessed out of the box. The SD reader is supported by the sdhci module which ships with the stock kernel.

Controlling fan speed

Install the i8kutils package and load the i8k module with:

modprobe i8k force=1

You can control the fan speed by running i8kmon and see the current temperature and fan speed by doing:

cat /proc/i8k

which will return in order:

1. BIOS version
2. serial number
3. CPU temperature
4. fan status
5. fan rotation speed (only on some models)
6. ac power status
7. volume buttons status (not the multimedia buttons)

External USB modem

TBD

Bluetooth

Works out of the box. Install gnome-bluetooth, bluez-gnome and gnome-vfs-obexftp if you want to be able to navigate inside the memory of your mobile phone (it must support Obex file transfers, almost every mobile does nowadays) using nautilus.

To associate a mobile with your laptop, search for the laptop from the mobile, try to connect to it and enter a PIN. When a connection is attempted, the laptop will prompt you for the secret PIN that you entered on your mobile.

To send files from mobile to laptop:

Run Applications / Accessory / Bluetooth File Sharing

A new icon will appear in the tray bar. When a file is sent to the laptop, a prompt will appear.

To send files from laptop to mobile:

Open nautilus and right click on the file, choose ‘Send to…’ and choose Bluetooth (OBEX Push) in the drop-down menu.

TBD: GPRS/UMTS connections via Bluetooth

Fingerprint reader

If your Dell XPS m1330 has a fingerprint reader, install the thinkfinger (http://thinkfinger.sourceforge.net/) package. A nice howto for Ubuntu with repositories and step-by-step instructions is available at https://wiki.ubuntu.com/ThinkFinger .

Misc: battery

My laptop is equipped with a 85 WHr 9-Cell Li-Ion battery (the largest available, at least at the time I placed the order).

The battery doesn’t follow the flat shape of the laptop. It provides an alternative base for the bottom of the rear of the laptop and slightly lifts the rear part up. This way the keyboard is gently inclined and very comfortable to use. The downside of this is that you lose stability when holding the laptop on your lap (!) and after some time it starts to hurt your legs.

So you face the dilemma: why would you want to have a longer battery life if this comes at the price of hurting your legs when travelling? Why would you need to have a bigger battery just to keep the keyboard inclined when sitting at the desk, where you don’t need battery power? :)

The laptop can run on battery power for about 4 hours / 4 hours and 20 mins with WiFi and Bluetooth disabled.

The battery life goes down to about 3 hours / 3 hours and 20 mins with WiFi and Bluetooth enabled.

The screen brightness doesn’t seem to make much difference on power consumption, this is probably because of the White Led LCD screen. If your laptop has a traditional CCL LCD screen, things could be different. Like always, when talking about battery life YMMV.

Misc: suggestions for saving power

These are some generic suggestions that will work with most laptops, not only Dell XPS m1330.

Add options usbcore autosuspend=1 to /etc/modprobe.d/options

Run /usr/bin/hal-disable-polling –device /dev/scd0 to allow the CD/DVD rom to spin down after a while.

Add

• vm.dirty_writeback_centisecs=1500
• vm.laptop_mode=5

to /etc/sysctl.conf .

Add /sbin/iwpriv eth1 set_power 5 to /etc/rc.local and make sure that it gets executed at boot time.

Kudos to Philip Langdale who started this madness on his blog at http://intr.overt.org/blog/?page_id=56 with an article on how to run Slackware on Dell XPS m1330.

Contacts

If you have any feedback, feel free to contact me.

E’ terribile l’abitudine di certe case produttrici a non fornire assieme alle motherboard le 2 porte usb da montare sul frontale del PC.
Valeva anche per la mia motherboard, una Gigabyte 7DX, per la quale disponevo delle sole 2 porte usb saldate sul retro. Per fortuna son riuscito a “recuperare” in redazione due porte usb 2.0 aggiuntive di una motherboard Abit.

La piedinatura ovviamente era diversa, ma il connettore per fortuna era identico: usb1.x e usb2.0 utilizzano infatti gli stessi segnali.

Ho staccato i contatti dal connettore che deve essere inserito sulla motherboard e li ho controllati con un tester. Confrontando il pin out delle porte usb descritto sul sito http://www.networktechinc.com/technote.html con il colore dei cavetti che uscivano dal connettore, ho potuto verificare la seguente corrispondenza tra colori e segnale:

Rosso= +5 VCC
Bianco= Data -
Verde= Data +
Nero= Massa

Sul manuale della Gigabyte 7DX (reperibile in pdf sul sito della casa madre) ho trovato il pin out utilizzato dal connettore sulla motherboard.

Ho ricollegato i cavetti secondo tale scheda et voila’, 2 nuove porte usb disponibili :)

E fu così che la mia webcam tornò ad essere online 24h/24 … sono meglio del Grande Fratello :=)

Un grazie a mauro_png per il sostegno tecnico/morale :)

Il sito riporta testualmente:

A really alpha cpufreq driver have been written. Look at ftp://ftp.poupinou.org/cpufreq/speedstep-ali.trunk.diff

By now, this driver have been reported to not work. I don’t know what to do next.

Capite il sacrificio estremo che ha fatto quest’uomo per sviluppare il driver?

Per citare il mio amico kah, quest’uomo … ha sviluppato qualcosa di più grande di lui.

Live long and prosper, my friend.
