Centos Modem:E3531 is not working

Post by jakub.jnbm » 30 Jun 2014, 08:52

Hello,

I bought a modem Huawei E3531 to send sms via bash. Problem is when i run switch mode i don't see device connected as /dev/sttyUSB.

Can somebody please help me? It's quite urgen, because i need to setup monitoring. Thx a lot.

I ran this command to switch the modem

Code: Select all

usb_modeswitch -v 12d1 -p 15ca -V 0x12d1 -P 0x14dc -M "55534243000000000000000000000011060000000000000000000000000000"
After command i get this:

It is possible that there are no serial tty interfaces in this device, the E3531 I have come across are all ncm devices which should be handled by the huawei_cdc_ncm driver.
Paste an output from lsusb -v -d 12d1:1506 in your next post and I will then be able to tell you what kind of interfaces your dongle have.

There is also discussion named
Huawei E3531 does not automatically switches to modem mode
Where was showed log which has the /dev/ttyUSB with the same model of the modem

That was a problem of a new usb id + problem to switch mode on a USB 3.0 port which is a hub driver problem, your dongle has a different firmware with different interface attributes and yours does switch.
You should btw replace 0x14dc with 0x1506 in your usb_modeswitch cmd line.

Your dongle is:

Interface #0 utps_modem (serial ppp dialup modem)
Interface #1 direct ethernet ncm
Interface #2 utps_diag
Interface #3 utpc_pcui
Interface #4 usb mass storage
Interface #5 usb mass storage

so interface #1 should be driven by the huawei_cdc_ncm driver in order to get the highest possible speed and the 3 utps type interfaces should be driven by the option serial driver which will create 3 ttyUSB devices under /dev
You can probably use the dongle for ppp dialup instead of direct ethernet but be aware that the dongle is primarily intended for direct ethernet and we have seen firmwares in the past where the ppp dialup doesn't work well when there is a ncm direct ethernet interface in the dongle.

Your firmware version is currently not supported by linux ncm drivers, it has to be added for upcoming linux releases.
It is supported by the serial option driver though but you will need a very recent option driver which has support for bInterfaceSubClass 3 (see your lsusb listing).
bInterfaceSubClass 3 got option driver support 7-8 month ago which is about the same time as E3531 appeared on the market.
I would guess that your Centos distro does not have such a recent option driver and that would explain why you don't get any ttyUSB devices created.

It is supported by the serial option driver though but you will need a very recent option driver which has support for bInterfaceSubClass 3 (see your lsusb listing).
bInterfaceSubClass 3 got option driver support 7-8 month ago which is about the same time as E3531 appeared on the market.
Yes, I remember noticing that and wondering what we should do about the network device drivers....

I guess the lsusb listing here is enough proof that we should add subclass 3, protocol 22 to the huawei_cdc_ncm driver. But I have a feeling that there might be more...

jakub.jnbm, could you please upload the *.inf files from the Windows drivers coming with this modem? They might give us some more hints about what to expect in the future.
