Support for D-link DWM-222 with new firmware does not create lte interface

RouterOS
1

Hi,
I’ve got used D-link DWM-222, rev A1, sticker says FW Ver. 2.1.2EU.

after connecting it to Hex refresh (E50UG), RouterOS version 7.20.4, it does not create LTE interface, or serial port.

On mikrotik help I found “H/W ver: A1 - supported as config-less LTE interface from v6.38“

in /system/resource/hardware i see:

1   location="1-1" parent=1-0 type=usb vendor="Mobile Connect" name="Mobile Connect"
serial-number="dacf919d23ff" vendor-id="0x2001" device-id="0xab00" speed="480" usb-version=" 2.01"
irq=0 device-path=bus/usb/001/00

From what I could find and my speculation:

after updating to version higher than 2.0.1, the device changed it's USB ID and is no longer exposing the same interface and starts supporting RNDIS.

Downgrading the device to older firmware fails (the script does not see the device).

On windows, this device shows as empty SD-card reader. After ejecting, this device shows as different device. (This actually allows the downgrade to see the device, but it fails anywas later)
the device after ejecting is D-Link USB Composite Device 2001.
before eject:

idVendor:                        0x2001
idProduct:                       0xAB00

after eject:

idVendor:                        0x2001
idProduct:                       0x7E35

Any ideas on how to:

  • Connect the device in current mode.
  • Try "ejecting" the device on Hex? (it does not appear in /disk)
  • Downgrading the firmware?

Thanks everyone,
Jan

Have you contacted D-Link?

Why would it be a MikroTik problem if updates to another manufacturer's device stop it from working with MikroTik?

Should MikroTik be the one to deal with problems with other manufacturers' devices?

You have to switch it back to modem mode it is currently in storage mode.

It is one of those "smart" devices (in the intention of the developers) the flip-flops between two settings, mass storage vs. actual modem.

You can read something about it here (but the program is Linux only):
