T99W175 / dw5930e on ZBT Z8102ax: Modem not working

[davidohne]

Expected Behavior

The modem is detected via lsusb and serial ports are created (ttyUSB0-3) and it should be possible to connect via MBIM protocol and ModemManager. The modem is in USB mode (normal modules are mPCIE only).

Current Behavior

MBIM is not working. Modemmanager does not find the modem. The serial ports are not open and it's not possible to communicate with one of them. In ROOter the modem gets detected and a connection is possible.

Possible Solution

I tried to install nearly everything which is also installed on ROOter, but that did not help. They are using some specific plugins which do not exist on omr like rmbim and rqmi.

In ROOter the modem logs shows the following:

Okay, some more progress:
When removing modemmanager, I'm able to connect to ttyUSB0 with minicom and I'm able to send AT+commands.

Installing modemmanager again results in the following. Don't know if this is a modem manager related problem or omr :-/
AT+commands can not be sent to the modem anymore. Even with "cat -e ..." and just monitoring the output with cat /dev/ttyUSB0

[davidohne]

Okay. I've found a solution. The problem is because of modemmanager. Modemmanager does not map the ports correctly.
I've added the following to /lib/udev/rules.d/77-mm-cinterion-port-types.rules and the modem is detected, I will have to do further testing. The ports are definetly not mapped correctly but ttyUSB0 is accessable:

# T99W175
#  ttyACM0 (if #0): AT port
#  ttyACM1 (if #2): AT port
#  ttyACM2 (if #4): can be AT or GNSS in some models
#  ttyACM3 (if #6): AT port (but just ignore)
#  ttyACM4 (if #8): DIAG/QCDM
ATTRS{idVendor}=="1e2d", ATTRS{idProduct}=="00b3", ENV{.MM_USBIFNUM}=="00", SUBSYSTEM=="tty", ENV{ID_MM_PORT_TYPE_AT_PRIMARY}="1"
ATTRS{idVendor}=="1e2d", ATTRS{idProduct}=="00b3", ENV{.MM_USBIFNUM}=="02", SUBSYSTEM=="tty", ENV{ID_MM_PORT_TYPE_AT_SECONDARY}="1"

Okay. I've found a solution. The problem is because of modemmanager. Modemmanager does not map the ports correctly. I've added the following to /lib/udev/rules.d/77-mm-cinterion-port-types.rules and the modem is detected, I will have to do further testing. The ports are definetly not mapped correctly but ttyUSB0 is accessable:

# T99W175
#  ttyACM0 (if #0): AT port
#  ttyACM1 (if #2): AT port
#  ttyACM2 (if #4): can be AT or GNSS in some models
#  ttyACM3 (if #6): AT port (but just ignore)
#  ttyACM4 (if #8): DIAG/QCDM
ATTRS{idVendor}=="1e2d", ATTRS{idProduct}=="00b3", ENV{.MM_USBIFNUM}=="00", SUBSYSTEM=="tty", ENV{ID_MM_PORT_TYPE_AT_PRIMARY}="1"
ATTRS{idVendor}=="1e2d", ATTRS{idProduct}=="00b3", ENV{.MM_USBIFNUM}=="02", SUBSYSTEM=="tty", ENV{ID_MM_PORT_TYPE_AT_SECONDARY}="1"
ATTRS{idVendor}=="1e2d", ATTRS{idProduct}=="00b3", ENV{.MM_USBIFNUM}=="04", SUBSYSTEM=="tty", ENV{ID_MM_PORT_TYPE_GPS}="1"
ATTRS{idVendor}=="1e2d", ATTRS{idProduct}=="00b3", ENV{.MM_USBIFNUM}=="06", ENV{ID_MM_PORT_IGNORE}="1"

Thank you for this hint!

I am using the USB enclosure "ID 1e2d:00b7 Gemalto M2M GmbH Generic Mobile Broadband Adapter" (or rather: ADT.LINK WS18-02) with a DELL-branded T99W175 on Debian Bookworm amd64 and constantly got "Failed to find primary AT port" among other errors.

Using this Udev rule (while changing 1e2d:00b3 to 1e2d:00b7 on all rules), I was finally able to let ModemManager find this modem.
I leave this here for anyone who might be looking for a solution for the same adapter.
