      I suggest to focus on 3372. Make sure your USB port is capable to provide enough current, 3272 requires more than 3372.
      In some cases those modems were working better when connected via relatively short (~15-20cm) extension cable instead of being plugged into the port directly.

      I'm +1 for testing on a non-virtualized install.

        2. I tested on an active USB hub. Unfortunately, no changes.

        3. I tested on a USB cable (0.5 m length). Unfortunately, no changes.

        4. Attempt to install on a physical machine ends with an installer error. Error occurs before he is to boot into the installer menu (maybe because of the soft-raid controller).

        Best Regards,
        Robert

          Everything is working now. I changed processor to a more powerful with VT-d support. I added via VMDirectPath I/O passtrough USB 3.0 chip to virtual machine and connected modem.

                @robertw Hi Robert, Im a newbie to pfSense and Im trying to implement my own pfSense using Huawei E3372h-607 as in stick mode as well. And Im having trouble with dial PPP for the 3G modem. Here's my current configuration:

                • Bus /dev/usb Device /dev/ugen1.3: ID 12d1:1c05 Huawei Technologies Co., Ltd. Broadband stick (modem on)
                • ugen1.3: <HUAWEIMOBILE HUAWEIMOBILE> at usbus1
                  u3g0 on uhub1
                  u3g0: <HUAWEIMOBILE HUAWEIMOBILE, class 0/0, rev 2.10/1.02, addr 3> on usbus1
                  u3g0: Found 3 ports. (which are /dev/cuaU0.0, 0.1 and 0.2)*
                  Though I can't manage to get it to receive IP address
                  Any help is appreciated, thank you in advanced!

                  What have you tried so far? What was the result?

                    Hi Stephen, thank you for replying. So far I have flash the modem with firmware 21.x and connect it with pfSense 2.4.3 exactly like the document said. I even issued AT setport command with “FF; 10,12,16”. Still I can’t get pfSense to dial ppp correctly. I checked the log and sometimes see IPADDR 0.0.0.0 DNS 0.0.0.0 etc. I’ve been scratching my head for a few days with this problem.

                      Ok, so it is detected by pfSense and u3g attaches to it. And the 3 usb serial devices are created?
                      And at least one of them responds to AT commands?
                      But you can't actually dial out?

                      I think we will need to see some log excerpts. It sounds like it's mostly working though, maybe some quirk with your provider.

                        @stephenw10 yeah, at least that's what I thought. I used the cuaU0.0 to dial AT command. I started to think there's a problem with the firmware version I flashed it with. And btw, I flashed another device and I get the error: cannot get device information. Any help is appreciated! Thank you so much Stephen

                          Did you try all three ports? It's not necessarily the first one that provides modem access.
