Huawei AT-commands
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 most Huawei devices. Using an AT-command, that activates SC or N on a device, which hasn't these components will result in errors and so will be noneffective.

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

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

To disable or re-enable those components run the following AT-command, where n is one of the numbers from the table below:

* 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

Sometimes AT-commands will result in an "ERROR" - in this case keep re-entering the AT-command until "OK" is being returned.
