Please refer to the original bug report if more details are needed.

The Haier CE81B CDMA modem (VID 0x201e, PID 0x10f8) exposes several
TTYs, but only one of them can be used for data connections. If other
interface is used, the modem will report a successful connection, but
pppd won't be able to setup the IP session:

  NetworkManager[3242]: <info> Activation (ttyUSB2) Stage 4 of 5 (IPv4 Configure Timeout) started...
  NetworkManager[3242]: <info> (ttyUSB2): device state change: ip-config -> failed (reason 'ip-config-unavailable') [70 120 5]
  NetworkManager[3242]: <warn> Activation (ttyUSB2) failed.
  NetworkManager[3242]: <info> Activation (ttyUSB2) Stage 4 of 5 (IPv4 Configure Timeout) complete.
  NetworkManager[3242]: <info> (ttyUSB2): device state change: failed -> disconnected (reason 'none') [120 30 0]

The original reporter made it work by blacklisting if#0 to if#2, while
leaving if#3 as the only TTY allowed to be used by ModemManager:

  # Haier CE81B
  ATTRS{idProduct}=="10f8", ENV{.MM_USBIFNUM}=="02", ENV{ID_MM_CANDIDATE}="0"
  ATTRS{idProduct}=="10f8", ENV{.MM_USBIFNUM}=="01", ENV{ID_MM_CANDIDATE}="0"
  ATTRS{idProduct}=="10f8", ENV{.MM_USBIFNUM}=="00", ENV{ID_MM_CANDIDATE}="0"

The contents of the mounted CD drive are also available:

The suggested fix is to prepare a new "haier" plugin that flags #if3 as
'data'.

Patch.

This new plugin just creates a generic broadband modem but tags #if3 as
being the primary+data port, so that it takes predenced over any other
tty grabbed.

Dan; you requested the mounted CD contents as well to the reporter, is
there anything else from there that can be included in the plugin?

INF files say:

%VENDORMDM% = Modem2, USB\VID_201E&PID_10F8&MI_03
%VENDORDIAG%  = QportInstall00, USB\VID_201E&PID_10F8&MI_00
%VENDORAT%  = QportInstall00, USB\VID_201E&PID_10F8&MI_02
%VENDORNMEA%  = QportInstall00, USB\VID_201E&PID_10F8&MI_01

so yeah #3 should be primary + data like you say.

Messaging seems to be done with the proprietary Qualcomm messaging
commands like AT$QCPMS, AT$QCNMI, AT$QCMGD, AT$QCMGR, AT$QCMGL, but we
also have AT+BMCGMR.

There might be some PIN operation support too with the regular 3GPP PIN
commands.

So if the modem works fine with regular CDMA commands and DIAG then
great, otherwise if somebody cares enough some other support could be
added later.
