Huawei E303 modes
Hi
After spending a while trying to get the Huawei E303 to send a SMS I finally got this to work.
Plugging in the device showed the USB device: ID 12d1:1f01 Huawei Technologies Co., Ltd.
Running the command:
usb_modeswitch -v 0x12d1 -p 0x1f01 -V 0x12d1 -P 0x14dc -M "55534243123456780000000000000a11062000000000000100000000000000"
Created this device
ID 12d1:14dc Huawei Technologies Co., Ltd.
and dmesg shows:
eth1: register 'cdc_ether' at usb-0000:00:1a.0-1.3, CDC Ethernet Device, 58:2c:80:13:92:63
scsi13 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 12
so this created eth1 and /dev/sdc (the micro SD card)
Running the command:
usb_modeswitch -v 0x12d1 -p 0x1f01 -V 0x12d1 -P 0x14dc -M "55534243000000000000000000000011060000000000000000000000000000"
Created this device
ID 12d1:1001 Huawei Technologies Co., Ltd. E169/E620/E800 HSDPA Modem
and dmesg shows:

Re: Huawei E303 modes
This is the 'fall-back' mode of several (but not all) more recent Huawei modems. It gives you the standard PPP interfaces as opposed to the faster - but proprietary - HiLink mode. So if you choose compatibility over speed, you are better off with your solution.

Re: Huawei E303 modes
Thanx for this!
Just FYI - if you install usb-modeswitch with it's data packages - the rules auto-switch the device into the "wrong" mode if you are looking to use fallback-mode.
If you want to use the ttyUSB* devices, DO NOT install the data package just the app. then use the info here to switch to the fallback mode. (I've spent hours today trying to figure out why the hell I could switch to fallback mode yesterday, and then not after a reboot. Turns out that - with the data package installed (which gets installed by default if you install via emerge on gentoo) udev auto-switches the device out of default mode to hilink mode the moment the device is picked up)
You can automate the switch in a similar manner via udev by creating a file under /etc/udev/rules.d/
Example:
/etc/udev/rules.d/ 40-E303Switch.rules
/bin/E303Modeswitch.sh:

Re: Huawei E303 modes
Why? There is nothing prohibiting you from editing the 12d1:1f01 file in the data package and change the switch message instead of making a whole new file and a new the udev rule.monkinsane wrote: If you want to use the ttyUSB* devices, DO NOT install the data package just the app.
Re: Huawei E303 modes
On my E303 to go to fallback mode I had to use the following as the above didn't work for me
without the -n -I, mine wouldn't switch form 1f01. I needed it to become 12d1:1001 to work as a serial PPP rather than ethernet.
Code: Select all
sudo usb_modeswitch -v 0x12d1 -p 0x1f01 -n -I -M 55534243123456780000000000000011060000000000000000000000000000
Re: Huawei E303 modes
I've been trying for days to get this dongle going on the arduino Yun
i've reset the Yun more then once , and once i got the 12d1:1f01 address but now it's always 12d1:14db
does that make a diffference to use the modeswitch ? (set to 14dc)

Re: Huawei E303 modes
I don't think it makes a difference. Different versions of the Huawei E303 seem to use different product IDs for the ethernet and fallback modes.
Specifically, I had a E303s-2 (HW version CH2E303SM) and now I have a E303h-1 (HW version CH1E3531SM). (You can see your exact model id inside the stick at the spot usually covered by the SIM card, and the HW version can be found out from the web interface)
The needed modeswitch commands differ slightly and so do the target product IDs.
For my old E303s-2:
Switch to Ethernet mode:
all worked equally, and in all cases lsusb would show
(except for that device number 042 which is dynamic, of course)
Switch to Fallback mode:
all worked equally, and in all cases lsusb would show
This looks like what you described, you may have that or a similar version.
For my new E303h-1:
Switch to Ethernet mode:
both work, and in both cases lsusb shows
So, same thing as for the OP (duncannweb).
Switch to Fallback mode:
work equally, and in both cases lsusb shows
So, here the target product ID of the fallback mode differs fom the post of the OP and any other posts in this thread. If I give the wrong ID to usb_modeswitch (e.g., -P 0x1001), no mode switch occus.
But most importantly, with the new stick when trying to switch to fallback mode, dmesg's output looks completely different, and no /dev/ttyUSB* devices are created. So I cannot use the new stick as a broadband modem!
Can anyone explain this? How could I use my new stick as a broadband modem?

Re: Huawei E303 modes
Thanks for your answer. I tried those switch messages and I can confirm they work. Using your help I can now switch to broadband modem mode!
So, on my E303h-1,
- 12d1:1f01 is the default (mass storage device) mode
- I can switch to 12d1:14dc ("ethernet" mode) using either 55534243123456780000000000000011062000000101000100000000000000 (standard) or 55534243123456780000000000000a11062000000000000100000000000000
- I can switch to 12d1:1001 (broadband modem mode) using 55534243123456780000000000000011063000000100010000000000000000
- I can switch to 12d1:1442 (???) using 55534243000000000000000000000011060000000000000000000000000000
What is this 12d1:1442? Is this just some kind of bug? I mean, apparently a modeswitch occurs with that message (product id changes), but I can't tell what it might be good for.

Re: Huawei E303 modes
You can probably find other msg's by inserting 1's in other positions but that is of no value and neither is the msg above. The reason why it is of no value is:einheitlix wrote: - I can switch to 12d1:1442 (???) using 55534243000000000000000000000011060000000000000000000000000000

Doesn't behave same on different firmware version.
Is not acknowledge by Huawei and they are the only ones who knows its purpose.
Huawei has given us two different kind of messages which has been tested by them on all of their products and these two messages covers normal use scenarios. Any other switch msg which their firmware acts on are Huawei propritary msgs and there is no explanation about them.
Re: Huawei E303 modes
Thanx for all your answers;
I had been succesfull to do a modeswitch on a arduino Yun with a E303 Huawei dongle.
in the file /etc/usb_modeswitch.d/12d1:1f01 :
added a file /etc/usb_modeswitch.conf and edit with :
I was glad that i finally got it working. But now i have 13 dongles E303 to be installed on Yun boards , and i can't get
them to work; They are the same , Huawei E303 but they dont work. The original switched to 12d1:1001 with the messagecontent
shown above. I tried the different messagecontents that are shown here in this topic but none of them work.. UUUHH!
Anyone can point me in the good direction ? thanx in advance !

Re: Huawei E303 modes
I have a Huawei E303 and I am quite desperate to make it work in modem mode.
lsusb reports device as: ID 12d1:14db Huawei Technologies Co., Ltd.
But when I try to
sudo usb_modeswitch -v 12d1 -p 14db -M "55534243000000000000000000000011060000000000000000000000000000"
I got the following reply:
Looking for default devices ...
found matching product ID
adding device
Found device in default mode, class or configuration (1)
Accessing device 005 on bus 001 ...
Getting the current device configuration ...
OK, got current device configuration (1)
Using first interface: 0x00
Error: message endpoint not given or found. Aborting.
How should I proceed? I did not find an resolution when you get "message endpoint not given"

Re: Huawei E303 modes
I´m desesperate too. I tried all usb_modeswith -v -p ......... I found and no one helps me. I´m not sure which is the modem mode 1001? 1442?
Re: Huawei E303 modes
I have managed to make it run. What I did is the following:
In folder /usr/share/usb_modeswitch you should have the vendor:product pairs for many devices.
I have copied file 12d1:1f01 to /etc/usb_modeswitch.d
and edited file as follows:
# Huawei E353 (3.se)
TargetVendor= 0x12d1
TargetProduct= 0x1001
MessageContent="55534243123456780000000000000011063000000100010000000000000000"
NoDriverLoading=0
Rebooted Raspberry PI and now modem shows correctly as ttyUSB0/1/2.
Hope this helps.
I have followed the setup logic found here:

and here
