hi, i've tried to follow different advices but I can't arriver to switch my dongle.

I've connected a Huawei E3531 dongle to a PI Zero W.

Here is my configuration file :

sudo nano /etc/usb_modeswitch.conf

Code: Select all

DefaultVendor= 0x12d1
DefaultProduct= 0x14dc
MessageContent="55534243123456780000000000000011062000000100000000000000000000"

Here is the response :

sudo usb_modeswitch -c /etc/usb_modeswitch.conf

Code: Select all

Note: No target parameter given; success check limited

Have you an idea of the problem ?

[LOM]

You can not switch 12d1:14dc, it is a usb id after a successful switching and it can not be further switched.

You can not switch 12d1:14dc, it is a usb id after a successful switching and it can not be further switched.

Ok, When I plugged my 3G dongle I can see in syslog that this message :

and then :

Code: Select all

As you see, it looks the dongle is still recognized as an USB Mass Storage device detected. Do you understand where is the problem ?

[Josh]

It's not unusual for current modems to provide their "CD" storage again even when in modem mode.

All in all, the syslog looks OK. Try to direct your browser to 192.168.8.1 afterwards.

I've found a trick to unswitch !!!

You have to remove modeswitch and install it again

Code: Select all

sudo apt-get remove usb-modeswitch usb-modeswitch-data
sudo apt autoremove
sudo reboot

Unplug your dongle and connect it again.
If you run lsusb you will get something like

Code: Select all

Bus 001 Device 006: ID 12d1:1f01 Huawei Technologies Co., Ltd. E353/E3131 (Mass storage mode)

You can install modeswitch again again :

Code: Select all

sudo apt-get install usb-modeswitch usb-modeswitch-data

then you add a configuration file like this :

Code: Select all

sudo nano /etc/usb_modeswitch.conf

Code: Select all

DefaultVendor= 0x12d1
DefaultProduct= 0x1f01
MessageContent="55534243123456780000000000000011062000000100000000000000000000"

Code: Select all

sudo usb_modeswitch -c /etc/usb_modeswitch.conf

You should see this logs :

Code: Select all

Look for default devices ...
   product ID matched

Access device 006 on bus 001

Current configuration number is 1

Reset response endpoint 0x81

-> Run lsusb to note any changes. Bye!

And if you run again lsusb you will have this time something like

I really think you need to read the usb_modeswitch doc page and also the README files. What you suggest will screw up the configuration of the usb_modeswitch system.

• "/etc/usb_modeswitch.conf" is the global configuration file. Don't put device config data in there.

• To disable the automatic mode-switching (which is working well on your system), don't uninstall usb_modeswitch. Just set the respective option in the global config file, and nothing will happen when you insert the stick

• If you want to customize the configuration for your modem, copy its default config file from "/usr/share/usb_modeswitch" to "/etc/usb_modeswitch.d", then edit it to your liking. It will be used automatically and take precedence over the default configuration.

Thanks for your advice.

I've reinstalled my RPI to be sure to follow the installation procedure.

So this time I've create directly this file : sudo nano /etc/usb_modeswitch.d/12d1:1f01

Code: Select all

MessageContent="55534243123456780000000000000011062000000100000000000000000000"

I've installed modeswitch as usual : sudo apt-get install usb-modeswitch usb-modeswitch-data

This command response : dmesg | grep tty | grep usb

Code: Select all

last lines of output should now show it attached to ttyUSBX
[153.452085] option1 ttyUSB0: GSM modem (1-port) converter now disconnected from ttyUSB0
[153.452879] option1 ttyUSB1: GSM modem (1-port) converter now disconnected from ttyUSB1
[153.458673] option1 ttyUSB2: GSM modem (1-port) converter now disconnected from ttyUSB2

My goal is to use "gammu" to send and receive SMS.

Here is my problem.

I've installed gammu like this : sudo apt-get install gammu gammu-smsd

I've edited the configuration file like this :

Code: Select all

# Configuration file for Gammu SMS Daemon

# Gammu library configuration, see gammurc(5)
[gammu]
device = /dev/ttyUSB0
name = Téléphone sur le port USB série HUAWEIHUAWEI_Mobile
connection = at
# Debugging
#logformat = textall

[gammu1]
device = /dev/ttyUSB1
name = Téléphone sur le port USB série HUAWEIHUAWEI_Mobile
connection = at

[gammu2]
device = /dev/ttyUSB2
name = Téléphone sur le port USB série HUAWEIHUAWEI_Mobile
connection = at

# SMSD configuration, see gammu-smsdrc(5)
[smsd]
service = files
logfile = syslog
# Increase for debugging information
debuglevel = 0

# Paths where messages are stored
inboxpath = /var/spool/gammu/inbox/
outboxpath = /var/spool/gammu/outbox/
sentsmspath = /var/spool/gammu/sent/
errorsmspath = /var/spool/gammu/error/

CheckSecurity = 0
CheckBattery = 0

Then you have to restart the daemon : sudo /etc/init.d/gammu-smsd restart

Each time I send a SMS it works : sudo gammu-smsd-inject TEXT <MOBILE PHONE NUMBER> -text "Test"

But when I reply, the SMS doesn't arrived in the directory /var/spool/gammu/inbox/ each time

I've done this test before to have installed NODE-RED on my RPI Zero W.

I don't think the problem is still related to my dongle which is well recognized by the system now.

If I find the problem.. I will put the link to the resolution... here

I'm going to post this "new" problem in another forum focused on gammu.

Thank you very much for your support

So it seems, the controller is insalled, but why I can't see ttyUSB0

I don't know what my mistake is.
Thank a lot for help!

By the way, is there any other way to switch back to 1f01 without the trick to uninstall usb_modeswitch?

[Josh]

Same advice applies - don't use /etc/usb_modeswitch.conf for device configurations !!

You likely have overwritten the original global configuration file with that name. Delete it, uninstall usb_modeswitch and re-install it. Then have a look at /etc/usb_modeswitch.conf again. If it exists, edit it and set "DisableSwitchingGlobal" to "1".
This will allow you to access the original mode 12d1:1f01.

If you want to try a custom configuration, create a file named "12d1:1f01" in /etc/usb_modeswitch.d and edit it. For an alternate Huawei mode that may provide a serial port use this configuration:

Code: Select all

Message="55534243123456780000000000000011063000000000010000000000000000"

You can leave out all other parameters while you are testing.

Then - with the modem still in storage mode, as "12d1:1f01", run this command:

Code: Select all

usb_modeswitch -v 12d1 -p 1f01 -c /etc/usb_modeswitch.d /12d1\:1f01

See if you get a serial port.
