      First thing would be to try a FreeBSD 12 snapshot to confirm it is recognised and working there. No point wasting time otherwise. https://download.freebsd.org/ftp/snapshots/ISO-IMAGES/12.0/

      Recompiling to get that into 2.4.4 is non-trival though.

        Any updates on this @stephenw10?

        I have the same modem ...

        # usbconfig
        
        ugen0.1: <Intel XHCI root HUB> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=SAVE (0mA)
        ugen2.1: <Intel EHCI root HUB> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA)
        ugen1.1: <Intel EHCI root HUB> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA)
        ugen2.2: <vendor 0x8087 product 0x8000> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA)
        ugen1.2: <vendor 0x8087 product 0x8008> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA)
        ugen0.2: <Mobile Connect Mobile Connect> at usbus0, cfg=255 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)
        

        I also noticed:

        # cat /usr/local/share/usb_modeswitch/2001:ac01
        
        # D-Link DWM-222 A2
        TargetVendor=0x2001
        TargetProduct=0x7e3d
        StandardEject=1
        

        Using Pfsense on non-Netgate hardware:

        2.7.2-RELEASE (amd64)
        built on Thu Dec 7 7:10:00 AEDT 2023
        FreeBSD 14.0-CURRENT

          @stephenw10, I also just found these announcements saying D-Link DWM-222 has been supported since FreeBSD 11.4; however, I am using Pfsense 2.7.2 which is on top of FreeBSD 14, and it doesn't seem to work at all.

            What are the actual USB IDs of your device? Manufacturers often change the hardware and use the same model name unfortunately.

            That device is listed: https://github.com/pfsense/FreeBSD-src/blob/RELENG_2_7_2/sys/dev/usb/usbdevs#L1762

              @stephenw10 I'm not sure if this is the right way to identify it as my experience with FreeBSD is very limited, but I got this: usbconfig_dump_device_desc.txt

              If I connect it to a Windows 11 laptop, I get this from the Device Manager:
              Screenshot 2024-03-31 122157.jpg
              Screenshot 2024-03-31 122027.jpg

              I also found these logs: system.log.txt

              And attempted a mode switch without success: attempt_modeswitch.txt

              Sorry I had to attach logs as files, but this forum is flagging everything I try to post as spam.

              Cheers,
              Gabriel.

                @stephenw10 As an additional experiment, I created a VM with FreeBSD 14 using a Proxmox environment I have and passed the entire USB through to it.

                On that one, I have this: experiment.txt

                I can see that it then shows cfg=0, which is different from cfg=255 that I got on the Pfsense machine. However, it still only seems to see one config?

                  OK so it shows up as a different product ID in pfSense/FreeBSD:

                    idVendor = 0x2001
                    idProduct = 0xac01
                  

                  If it has more than one config index you can force it use a different one. You can check that with, for example: usbconfig -d ugen0.2 dump_all_config_desc

                  Anyway ac01 is the device before it has been modeswitched:
                  product DLINK DWM222_CD_2 0xac01 DWM-222 CD-ROM Mode

                  You may simply be able to eject the virtual CD to switch it or run usbmodeswitch. Then recheck the usbconfig output to make sure it changed.

                  However u3g should be doing that already:
                  https://github.com/pfsense/FreeBSD-src/blob/RELENG_2_7_2/sys/dev/usb/serial/u3g.c#L247

                  I would try unplugging it then plugging it back in and checking the system logs. I'd expect to see u3g trying to switch it and attach to the ports.

                    How would you do the eject exactly? And the modeswitch?

                    Unplugging it and then plugging it again gives me only this in /var/log/system.log.

                    I don't see any messages with u3g in any file under /var/log. I searched for it everywhere. What would those logs look like? How do I know that u3g is running and/or working as exected?

                    I also added this to /boot/loader.conf:

                    u3g_load="YES"
                    hw.usb.ehci.iaadbug="1"
                    hw.usb.ehci.debug="1"
                    hw.usb.xhci.debug="1"
                    

                    But nothing new was printed to /var/log/system.log.

                      u3g is in-kernel you shouldn't need to load it.

                      You don't see the virtual CD drive either? You would need to see that in order to eject it.

                      The config does show a mass storage device which might be a uSD card slot for example. You don't see that logged either though?

                      If u3g works as expected you would see something like:

                      u3g0: Found 5 ports.
                      u3g0: <Huawei Mobile Connect - Modem> on usbus0
                      u3g0 on uhub0

                        Do you mean with camcontrol? If so, this is what I see:

                        The config does show a mass storage device which might be a uSD card slot for example. You don't see that logged either though?

                        u3g0: <Huawei Mobile Connect - Modem> on usbus0
                        u3g0 on uhub0
                        

                        I have zero logs from u3g. I searched with:

                        grep -lr "u3g" /var/log
                        

                        And it found nothing.

                        Now, as an experiment, I installed FreeBSD 14 (not Pfsense) on a VM and passed the entire USB port to it. This is not on the same hardware I am using with Pfsense. I managed to make it work with the VM as discussed here: https://forums.freebsd.org/threads/issues-with-d-link-dwm-222.92946/

                        Notice that on this successful experiment, I found messages from u3g in /var/log/messages in the plain FreeBSD installation. However, in Pfsense, I don't even have a /var/log/messages file. Why's that?

                        Then, I created a second VM with the Pfsense ISO instead of plain FreeBSD, and I managed to reproduce the exact same problem I am having with Pfsense on the bare metal.

                        In the VM, I passed the entire USB through to Pfsense, and I got: pfsense-vm.txt

                        There, I equally have no /var/log/messages and no logs from u3g.

                          Hmm, seems like that device might be in some odd mode then. The virtual CD drive function doesn't require any sort of driver. The USB ID implies it should be there but isn't for some reason.

                          I would check it in Windows. If it has some setup utility make sure it hasn't been set with something odd.
