Huawei BM325 12d1:3808 HELP

Post by polow » 08 Jan 2016, 17:49

Hello ,

I am trying to figure out how to run my USB Wimax Echolife BM325 on my Raspberry pi B+

So far i found these information about my Device on the forum posted by user "Xander" :

Code: Select all

Code:
# Huawei EchoLife BM325 WiMAX USB Modem
ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="3808", RUN+="usb_modeswitch '%b/%k'"
Config file :

Code: Select all

Code:

# Huawei EchoLife BM325 WiMAX USB Modem

DefaultVendor= 0x12d1
DefaultProduct=0x3808

TargetClass=0x02

CheckSuccess=20

HuaweiMode=1
I have installed USB modeswitch used the above code to switch my Wimax from CD mode to Modem mode but with no luck , i tried to use USBSniff but i didn't know how it works .

These all the information i gathered from my Raspberry\Wimax Dongle :

Code: Select all

pi@raspberrypi ~ $: sudo usb_modeswitch -v 0X12d1 -p 0X3808

USB modeswitch Doesn't support my Device and i don't really know how to manually configure it .
Another important note i gathered while making a research is the modem has three modes i quote :
"I've just made it work!
This device is very tricky actually. It can be in three states:
* 12d1:3808 mass storage
* 12d1:3809 mass storage
* 12d1:3808 cdc.
"

Rest of the information can be found here http://permalink.gmane.org/gmane.linux. ... eral/28113

I didn't know what does that means but i am sure he mentioned a Patch for USB mode that can make Huawei BM325 switch to modem mode .

Any help is appreciated

Try the cmd:
sudo usb_modeswitch -v 12d1 -p 3808 -H -W

then check if a verbose lsusb shows more interfaces than the storage interface.

Thank you so much i really appreciate your Help
Installed Fresh copy of Noobs OS on my PI , tried the code you mentioned but unfortunately same result :

My device is not in the List of USB Modeswtich even though a user mentioned the Configuration file , why didn't they included the new configuration in the new update ?

I installed USB modeswitch from the command "sudo apt-get install usb_modeswitch" is this right ?
should i install it manually using this bz2 file http://www.draisberghof.de/usb_modeswit ... .6.tar.bz2 ?
thank you

You have used that configuration file yourself without success and the user who provided it said that the switching was unreliable.
Why should that be included in an update when it doesn't work?

The hardware you use, the Raspberry Pi, is known for having an unreliable usb controller so I don't trust the results.
It looks like the usb port can not provide enough current for your wimax device which therefore resets itself.
What does your dmesg look like if you plug in the device but don't run usb_modeswitch, does it repeatedly disappear and comes back with a new device number on the bus like it did here:

You're totally right

After Installing Fresh Noobs OS this "dwc_otg" disappeared so i think i did something wrong obviously.

Just restarted my PI then attached the Wimax dongle and seems like it's attached as a CD-ROM and not restarting like it did before .

It's hard to say what is and what is not the problem.

If I see such an erratic behaviour of a USB device, I always try again using an externally powered USB hub. That often helps not only with tablets but also with embedded PCs like my Intel NUC machine. I also use it when testing on my Pi2.

Also, you can try some different switching sequences that are known to work on other Huawei devices (one at a time):

Code: Select all

########################################################
# Huawei EchoLife BM325 WiMAX USB Modem

DefaultVendor= 0x12d1
DefaultProduct=0x3808

MessageContent="55534243123456780000000000000011062000000101000100000000000000"
#MessageContent="55534243123456780000000000000011063000000100010000000000000000"

Call the file manually with the "-c" parameter:

Code: Select all

# usb_modeswitch -W -c <yourconfigfile>

This ought to switch the device:

sudo usb_modeswitch -v 12d1 -p 3808 -W -M 55534243123456780600000080000601000000000000000000000000000000

it is the last msg (and only msg of interest) in the usbsnoop log from the thread in the linux-usb mailing list you linked to.

Thank you :)

but looks like the code didn't switch the Modem , here's the output :

Code: Select all

~ $ sudo usb_modeswitch -v 12d1 -p 3808 -W -M 5553424312345678060                                                                                        0000080000601000000000000000000000000000000

ok, it looks like we are back at square one where user xander gave up 6 years ago and where I give up now.

I consider it a waste of time to continue because Wimax support in linux is extremely limited and there is nothing indicating that BM325 would be easy to support if the switching issue was solved.

When trying out mode-switching methods manually, make sure you unplug and re-plug the stick before every new attempt. Otherwise it may be in an undefined state.

Try the command again, but this time add the following parameters:

Code: Select all

sudo usb_modeswitch -v 12d1 -p 3808 -W -n -w 500 -M 55534243123456780600000080000601000000000000000000000000000000
Don't forget to re-plug the modem before.

Any changes?
