      @stephenw10 said in Huawei 4G/LTE USB findings:

      I would try to run usbconfig dump_all_desc against it in the various modes to see what interfaces it actually presents in each.

      If the device appears and then disappears in the Ethernet mode, is it actually changing there or is it FreeBSD doing something odd.

      To create a serial port to configure it in NCM mode probably requires u3g to recognise it. That device ID is not listed specifically though:

      Hi Steve

      I was hoping you would turn up in this thread ;-) Here's the deal:

      When plugged in, and I run the usb_modeswitch to 0x155e mode, the system logs:

      Apr 8 14:43:37 kernel ue0: Ethernet address: 00:1e:10:1f:00:00
      Apr 8 14:43:37 kernel ue0: <USB Ethernet> on cdce0
      Apr 8 14:43:37 kernel cdce0: <NCM Network Control Model> on usbus1

      Apr 8 14:43:35 kernel ugen1.2: <HUAWEIMOBILE HUAWEIMOBILE> at usbus1 (disconnected)
      Apr 8 14:43:35 kernel umass0: detached
      Apr 8 14:43:35 kernel (cd0:umass-sim0:0:0:0): Periph destroyed
      Apr 8 14:43:35 kernel cd0: <HUAWEI Mass Storage 2.3M> s/n 0123456789ABCDEF detached

      Apr 8 14:43:35 kernel umass0: at uhub1, port 1, addr 2 (disconnected)

      Basically it destroys the mass storage device as expected and finds the NCM instead.
      As you can see, the ue0 interface is dicovered, but no serial devices to control it (and bring up 4G) is found.
      Running your suggested command for the Huawei device once in 0x155e mode returns:

      Your link gets a little to technical for me to decipher what I can do to have pfSense discover the serial ports.

      EDIT: As far as I can see, it has one configuration to select in this mode (the currently active one).
      That configuration has 5 interfaces, but pfSense only discovers the ue0 Ethernet one. I suppose 1 of the remaining 4 is the serial control interface i'm missing?

      Love the no fuss of using the official appliances :-)

        @stephenw10 said in Huawei 4G/LTE USB findings:

        I would try to run usbconfig dump_all_desc against it in the various modes to see what interfaces it actually presents in each.

        If the device appears and then disappears in the Ethernet mode, is it actually changing there or is it FreeBSD doing something odd.

        To create a serial port to configure it in NCM mode probably requires u3g to recognise it. That device ID is not listed specifically though:

        Steve

        But I guess the "core" of your link is that 0x155e is not recognized as a Huawei USB device in FreeBSD 12, and as such it will load no serial drivers to the unrecognized devices.
        I just don't get why it finds the ue0 device then....?

        Also: the E3372h-320 in 0x155e mode is the most broadly available Huawei 4G dongle in northern europe - and has been for 3 - 4 years now, so how can that not be supported in FreeBSD yet?

        Love the no fuss of using the official appliances :-)

          Yes, there's only one config index shown so no change of selecting something different in pfSense. There are 5 interfaces shown but none is obviously a serial connection.

          Just as an example this is a modem that is supported by u3g:

          Resulting in:

          It finds the USB ethernet device on yoru modem because the cdce driver will attach to any cdc Ethernet device, it doesn't need to have the exact matching USB IDs.

            So no hope of getting that stick running? It is more or less he only stick you can buy these days, so it's a little difficult getting something else that will be supported.

            I'm guessing it's not so much a driver thing (likely the same drivers will work), but it's rather an issue where it doesn't recognize the ID/devices and then does not know which drivers to use to attach to the devices.
            Any chance I can low level edit something to make it attach the standard drivers to this 0x155e ID?

              @stephenw10 I should mention that It seems my Aruba AP’s use the CDC interface to make the 4G connection, so that is likely the interface to use. But whether that is the serial Interface or a API interface I don’t know. I can see your Huawei have the CDC as well, but also somthing called Serial B.

              Can you figure out which device number corresponds to the cuaUx.x interface you use to control the 4G connection with?

                Mmm, it's unfortunately difficult to add devices to u3g to test because the values are tied into the OS. You need to recompile everything.

                I see there are a number of threads reporting similar or identical responses with that device and no good result.
                The immediate disconnect thing is odd. Doesn't look like anyone else has found a reason for that either. 😕

                  Since this is a bit outside netgate’s jurisdiction (base OS driver updates), I guess there is no need to get my hopes too high.
                  Given BSD always had lackluster support in the cellular department, I’ll put this project on lifesupport until support for 4G dongles you can actually get is present.

                  But Thanks for the insight

                    I have two here, both are internal m.2 cards but still USB connected. Neither are current though so it's hard to recommend for a new deployment.
                    The only thing that will always work is an external Ethernet connected LTE modem.

                      Okay so after a lot of troubleshooting, I finally seem to have got this working, although I have got this working before on older pfsense versions.

                      Currently on a SG4860-1U running pfSense 23.05.1, I attached the Huawei E3372h-320 via USB.

                      Beforehand, please note that this worked on a previous version, somewhere last year (A older FreeBSD release, I think 12?), by just using usb_modeswitch and switching from Drive mode to USB Ethernet mode,
                      however, when currently doing that it doesn't recognize the device.

                      So after some digging I found out that it is now recognized in NCM mode, as described above in option 3, so with USB Product ID 0x155e.

                      Well, this made me want to just try using a PPP interface and one of the /dev/cuau ports, I tried them all.
                      Some responded, some didn't, the ones that responded however were still faulting:
                      CHAT: The modem responded with "ERROR" to the command "AT&F&C1&D2E0S0=0M1" at ModemCmd: label

                      Well, after a short amount of googling I found this topic:
                      https://forum.netgate.com/topic/53105/pfsense-and-huawei-e3276-4g/9

                      Which mentioned: "I found that running this manually and removing the S0=0 string it worked"

                      So, I did and put this in the init string field in the settings:
                      &F&C1&D2E0

                      And tadaaa, it worked, the interface is now correctly registered and received the WAN IP, no more double NAT, too, and no flashing at all :-)

                      Settings I configured in the PPP options:
                      /dev/cuaU0.0 (although, please try others too and see if the modem responds by reading the logs).
                      Phone number, #777, no idea if that is OK, although I think that I have to use a CDMA network, it works for my provider at least...
                      Sim pin,
                      Sim pin wait = 30, to be sure.
                      Init string with settings above.

                      That's it, then just assign it to an interface and be done with it.

                      No more usb_modeswitching, (I even removed the package), just working out of the box! (For now... hehe)

                        @randommen I’m not sure I understand. Does it switch automatically to NCM mode when inserted or after a reboot?
                        I assume pfSense still autodiscovers the Ethernet device side of the bridge when in NCM mode?

                        If it does, could you post a screenshot of your PPP/Serial port settings to actually control it/make it connect on the 4G side?

                          @keyser Yes it seems to switch to NCM mode automatically, no action taken, directly after plugging in and after reboot.
                          It does stil discover the ue0 device, too yes. Didn't try using it.

                          It is now working 20 hours concurrently.

                          See attachment, all the red things I configured, all the others I didn't really touch.

                          426f5cc3-c695-453c-bc5d-8185e585dc4e-image.png

                          Then just assign it to an interface and it is working.

                          I had to play around with the link interface, just try every single one and see what it does for you.

                          You can watch the PPP log under /var/log/ppp.log or system logs in the GUI.

                            @randommen Thanks - I’ll see if I can get time to play with it. I find it strange that you need to use serial interface as the actual datainterface. As far as I understand, the ue0 Ethernet interface should be a transparent bridge to the 4G connection and should be your WAN over Ethernet - just like any other Ethernet based WAN link.

                              @randommen That would eliminate the PPP part with all its performance and throughput issues….
