Huawei Hilink e3131

Hi guys.
I got Huawei HiLink e3131. Slackware 14.1 x86_64 recognizes it and switches into modem mode as you can see from dmesg:

Code:

...
[  532.663850] usb 1-9: new high-speed USB device number 5 using xhci_hcd
[  532.675616] usb 1-9: New USB device found, idVendor=12d1, idProduct=1f01
[  532.675618] usb 1-9: New USB device strings: Mfr=2, Product=1, SerialNumber=0

...

lsusb also shows modem:

Code:

...
Bus 002 Device 003: ID 12d1:14db Huawei Technologies Co., Ltd.
...

however there are no /dev/ttyUSB* files, so I cannot use it. What is more interesting cat /proc/tty/drivers shows:

Code:

...
usbserial            /dev/ttyUSB   188 0-253 serial 
...

Problem is the same on second computer with Slackware 14.0 x86 as well as Debian Jessie. Of course modem is ok - works fine under Windows 7. I've found some hints like

Code:

modprobe option
echo "12d1 14db" >/sys/bus/usb-serial/drivers/option1/new_id

but it's no use.
Any solutions?

No, it shows it as a CDROM/USB block storage device, and it clearly says so.

No, that just says you have a device by that manufacturer....where does it tell you that it's a modem??

Yes; run usb_modeswitch to actually make the device work as a modem, and the device will come up. Nothing you've shown says the device is a modem, just that it's recognized as a USB storage device. usb_modeswitch will 'flip' the device into modem mode.

Actually, the dmesg output shows that the device has been recognised and switched to CDC ethernet mode.

In this mode, the device should show as an additional interface in the output of 'ifconfig -a'.

No /dev/ttyUSB* files show in this mode, although it may be possible to get the device to switch to a serial port mode. http://www.draisberghof.de/usb_modes...php?f=4&t=1295

Right...it doesn't show up BECAUSE YOU HAVE NOT SWITCHED IT INTO THE RIGHT MODE. The device is identified, but hasn't been attached to anything. Again, run usb_modeswitch. Can't get more plain than that.
