          I've had a look at a few similar posts, and from what I can see this modem isn't supported in the 8.3 release of FreeBSD: http://svnweb.freebsd.org/base/release/8.3.0/sys/dev/usb/serial/u3g.c?revision=234063&view=markup. Unless anyone else has another idea I can only suggest you try a different modem - and check first if it's compatible with FeeBSD 8.3.

            It's stuck in CD-ROM mode and needs to be switched to modem mode. The device appears to be a ZTE K3806-Z not a Huawei. Some quick Googling shows it has a number of modes, you want to get modem mode not cdc-ether mode to work well with pfSense.
            There's no easy fix for this. You can probably install usb-modeswitch and change to the correct mode but you then need to hope that the resulting USB ID is something u3g knows about and creates serial ports for.

              Ok thank you so much so our replay :) . I think that it's more simple change device and pick one compatible with pfsense

              The thread for me it resolved

              Best
