      Hi, I bought a Sierra 7355 based off posts and some info saying it’s supported by pfsense.

      Pfsense is seeing it only as a USB device but it’s not an option to add to an interface.

      If I run USBConfig I do see it as : ugen1.2: <Sierra Wireless, Incorporated Dell Wireless 5808 Gobi 4G LTE Mobile Broadband Card> a, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

      Help would be greatly appreciated

        Check the USB IDs it reports with: usbconfig -d ugen1.2 dump_device_desc

        It shows as a Dell device so it will probably require setting to a different USB composition. You will need to do that in Linux or Windows if so.

            Yes that's a Dell Vendor ID and a Product ID that isn't known:
            https://github.com/pfsense/FreeBSD-src/blob/devel-main/sys/dev/usb/usbdevs#L1679

            You will need to update the USB composition and identity. Similar to this:

              1. Load Windows 10/11
                2.Go here - https://zukota.com/posts/sierra-wireless-em7455-how-to-enable-com-ports/. - Download the .IMA and make the USB as the guide describes and follow the steps.
                3.Back to windows - Follow the the BELOW guide up to the point where it says to connect to the COM port in windows via PUTTY
                https://zukota.com/posts/sierra-wireless-em7455-how-to-make-it-work-with-an-older-lenovo-laptop/
                4.Type the following in Putty once connected to the com port AT!UDVID=1199 and AT!UDPID=9041 and then at!reset
              2. back to PFSENSE, it should now show at least

                  I assume you found the correct port for the AT interface?

                    @stephenw10 It now shows 4 options in Pfsense, do you have any information on finding out which one to set as the gateway/interface in PPP?

                    I actually had a read of your old posts here, any idea why after it shows connected with "cu -l /dev/cuaU0.2" I cannot type anything after? I have to close the SSH session?

                    https://forum.netgate.com/topic/146920/help-with-sierra-wireless-mc7355/8

                    I now have 4 options /dev/cuaU0.0, /dev/cuaU0.1, /dev/cuaU0.2 and /dev/cuaU0.3

                    and it now shows as ugen1.2: <Sierra Wireless, Incorporated MC7355> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

                    bLength = 0x0012
                    bDescriptorType = 0x0001
                    bcdUSB = 0x0200
                    bDeviceClass = 0x0000 <Probed by interface class>
                    bDeviceSubClass = 0x0000
                    bDeviceProtocol = 0x0000
                    bMaxPacketSize0 = 0x0040

                      It might just not be configured to reflect back the characters you're typing. Try just entering: at at that port and see if it returns OK.

                      If you run usbconfig dump_all_config_desc against the device you will see the descriptions of each interface.

                        @stephenw10 I have no idea why but now it won’t show it as a option again in interfaces. So I have no ‘dev//cua.. option at all.

                        ugen1.2: <Sierra Wireless, Incorporated MC7355> at usbus1 shows Still though so it’s defo connected.

                        I thought this chip was the easier one to be honest, shame as I bought the aerials and wanted it all in one box. If it comes to it do you know any mpcie that just Works with eu sims?

                          Did you change the USB IDs? Is i still showing as those?

                          The USB serial devices in /dev are created by u3g when it recognises a device. So if it isn't creating them it's not seeing a device it supports.
