Dear all,

I do not want to hijack this thread, but I am having a problem with the same stick. Raspberry Pi B+ and Huawei E3531 3G Modem. If I enter lsusb in the terminal it acts as an usb stick. So I downloaded usb-modeswitch (sudo apt-get install usb-modeswitch), but nothing changed after reboot.

Code: Select all

Bus 001 Device 004: ID 12d1:15d2 Huawei Technologies Co., Ltd.

If I use the following command used earlier in this thread, also nothing happens

Code: Select all

sudo usb_modeswitch -v 12d1 -p 15d2 -M '55534243123456780000000000000011062000000100000000000000000000'

lsusb still gives

Code: Select all

Bus 001 Device 004: ID 12d1:15d2 Huawei Technologies Co., Ltd.

Any clue why my device does not switch at all?

Thank you very much
Roberto

I assume that you posted in that thread by mistake seeing that you didn't want to hijack it so I have moved your post into a separate thread.

Add the -W switch to your manual usb_modewitch cmd line and paste the output from the cmd in your next post.

First of all, yes I did want to start a new thread, sorry for that.

Just a note, I am accessing the Raspberry Pi via SSH from my desktop computer. The Raspberry Pi is connected via Ethernet to my router, headless. I have a fix IP running on the Raspberry, tightvncserver and ppp installed.

Here is the output of the cmd line command with -W

Code: Select all

pi@raspberrypi ~ $ sudo usb_modeswitch -v 12d1 -p 15d2 -M '55534243123456780000000000000011062000000100000000000000000000' -W

Unfortunately, the default Raspbian version of usb_modeswitch is rather dated.

Try adding the -I parameter to your commandline. This may result in an improvement.

I'm completely new to Linux, but I have a bit of programming knowledge. That is why I used apt-get, should I have used another version?

The hint with -I looks like it helped:


[Edit]Here's the command used

Code: Select all

sudo usb_modeswitch -v 12d1 -p 15d2 -I -M '55534243123456780000000000000011062000000100000000000000000000'

lsusb now gives

Code: Select all

Bus 001 Device 005: ID 12d1:15d3 Huawei Technologies Co., Ltd.

ifconfig -a now newly gives

Code: Select all

wwan0     Link encap:Ethernet  HWaddr 00:1e:10:1f:00:00  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

Now I wanted to get the modem to aquire an IP address, so I have added the following lines at the end of the file /etc/network/interfaces

Code: Select all

allow-hotplug wwan0
iface wwan0 inet dhcp

according to this link: http://garethhowell.com/wp/connect-rasp ... g-network/

Problem is, after

Code: Select all

sudo reboot

the modem is back in the USB state (12d1:15d2). Therefore also no success when running ifconfig -a and the ip address. I guess I need to add my usb-modeswitch command to the boot sequence? How would I do that? Many thanks.
