Huawei E173s

USB_ModeSwitch • View topic - Huawei E3231 - new model

Command to make it appears as /dev/ttyUSB0


So according to that comment we should consider this (and probably also the 2 endpoint variants) as "vendor-specific modem interfaces". I wonder if you get any ttyUSBx port responding to AT commands if you do:
Code:
modprobe option
echo 12d1 1c05  >/sys/bus/usb-serial/drivers/option1/new_id

Some minicom commands that can help you changing the settings of the modem

minicom -s (configure, change here the option "Serial port setup" -> "A -    Serial Device      :" to /dev/ttyUSB0

exit

type in your commands
example: AT^U2DIAG?
example2: AT^U2DIAG=276

Commands supported

Huawei AT-commandsThis is a featured page

note: Some devices like the Huawei K3715 seem to require AT-commands to be typed in capital letters!

There are a couple of options for disabling and re-enabling the following USB-components of Huawei USB-modems:

  • modem (M)
  • NAND-flashmemory drive (CD)
  • microSD-drive (SD)
  • PC UI interface (UI)
  • network adaptor (N)
  • smartcard (SC)
To disable or re-enable those components run the following AT-command, where n is one of the numbers from the table below:

AT^U2DIAG=n

On some models it is possible to read the present value of the parameter n by sending command:
AT^U2DIAG?

*) note: Smartcard (SC) and network adaptor (N) are not present in many Huawei devices. Using an AT-command that activates SC or N on a device without these components, will result in errors and so will be noneffective.


Modems supporting AT^U2DIAG? command: E173, E1750 ,E160E
 Modems not supporting AT^U2DIAG? command: E160, K3565

Also on some models it is possible to display a list of devices present in a USB-stick, by sending a command:
