ZTE dongles, at least, have means to disable mode switching and make the dongle power-up as a USB 3G modem. There are two possible commands
to use, depending on the age of the dongle: use 'AT+ZCDRUN=E', or if that isn't supported use 'AT+ZCDRUN=8' to force the dongle into modem mode.
To reconfigure the dongle, one needs a computer which supports 3G dongles and which can do mode switching in order to present an interface which
accepts AT commands.
For example, a Linux computer with the ''usb-modeswitch'' and ''usb-modeswitch-data'' packages can be used. Plugging in a ZTE MF112 dongle results
in 'dmesg' reporting:
option 1-1:1.0: GSM modem (1-port) converter detected
usb 1-1: GSM modem (1-port) converter now attached to ttyUSB0
option 1-1:1.1: GSM modem (1-port) converter detected
usb 1-1: GSM modem (1-port) converter now attached to ttyUSB1
option 1-1:1.2: GSM modem (1-port) converter detected
usb 1-1: GSM modem (1-port) converter now attached to ttyUSB2
Trying 'screen /dev/ttyUSB0' shows this port doesn't respond to 'AT' commands (use ^Ak to kill the session), but 'screen /dev/ttyUSB1' does respond
to 'AT' commands.
Out of the box:
