      Specifically the errors I get on 2.5 are:

      May 30 02:29:34 ppp 30609 [opt1_link0] CHAT: The modem is not responding to "AT" at ModemCmd: label.
      May 30 02:29:34 ppp 30609 [opt1_link0] MODEM: chat script failed

        And I think this is the error most relevant:

        94244 [opt1_link0] CHAT: The modem is not responding to "AT" at ModemCmd: label.

          As is says, the port is not responding to AT commands. You may have the wrong port selected.

          Try disabling/removing the ppp config from pfSense and then connceting to the port dircetly from the command line to see if it does respond to AT commands. Try all the ports if there is more than one com port presented.

            I'm not terribly familiar with FreeBSD/linux in general-how do I go about connecting to the port directly from the CLI? I'm in and I appear to have found it on ugen3.2 (idVendor=0x2001, idProduct = 0xab00) if that helps, but I don't know how to force a connection from here to see if I can initiate a connection-I guess it's a cu command? Or tip? Can you point me anywhere that might help?

              Not sure if any of this helps-I'm just going off what I found online elsewhere to try and round up some details:

              ugen3.2: <Mobile Connect Mobile Connect> at usbus3, cfg=255 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

                Additionally:

                  Ok first thing I would do is unplug it then plug it back in and check the system logs in the GUI.
                  If it's a supported device you will probably some entries as u3g creates new com ports. You might also see new usb ethernet devices detected.

                  If it as and new ports are created they will be /dev/cuaU*. The upper case U denotes a USB connected device. Those ports you show above are the on-board com ports not the modem.

                  Yes, you would connect to it using cu, for example:

                  [2.4.1-DEVELOPMENT][admin@3100.stevew.lan]/root: cu -l /dev/cuaU0.2

                          That device does look like it should be recognised but only in 2.5:
                          https://github.com/pfsense/FreeBSD-src/blob/RELENG_2_5/sys/dev/usb/usbdevs#L1725

                          It's not shown in 2.4.X. You will need to use a dev snapshot if you need native support.

                              Did you just upgrade to 2.5? If so check the system log again when you connect it.

                              You should see it shown as the correct device at least.

                                No, I’ve been on 2.5 since I opened this ticket. The logs above are from 2.5-the device isn’t being recognized

                                  The system log (again on 2.5) only shows the connection at 3.2 and then the failures to respond to AT. Do you perhaps have any further suggestions?

                                    Hmm, what I expect to see here is the device initially come up as an emulated CD drive and then be ejected by u3g:
                                    https://github.com/pfsense/FreeBSD-src/blob/RELENG_2_5/sys/dev/usb/serial/u3g.c#L241

                                    If you reboot and check the boot log do you see that?

                                    Do you see a cd drive listed in /dev that has no business being there? If so try ejecting it.

                                    Steve

                                      Rebooting seems to have frozen it-I'll need to get a monitor out tomorrow and take a look at what happened, but I did get an output of /dev at first-nothing obviously cdrom in there:

                                        No idea what happened, but something got corrupted and had to fully reinstall. But now can confirm both no unexpected CDROMs in /dev (it looks the exact same as above), it continues to mount on 7.2 and it doesn't work.

                                        Additionally (both before and after I create a PPP Interface) cu -l /dev/cuau* don't give me any interactive responses-I just get a dead cursor until I disconnect.

                                          Hmm, I would try it in some other OS at this point and see what it does there. It may be stuck in some odd mode perhaps.
                                          Do you know the history of that device?

                                            It's brand new, not locked, and works fine on my Windows box with the provided software...
