      I'm having the same problem with my ZTE MF668 (Rogers Rocketstick).  Initially pfSense was detecting it only as USB storage, so I couldn't select it as an interface in the PPP menu.  I plugged the modem into a Windows computer and this is what it reported in Control Panel: USB\VID_19D2&PID_2000 (before driver install) and USB\VID_19D2&PID_0017&MI_02 (after driver install).

      My Linux knowledge is rather limited, and I wasn't sure how to make pfSense do the mode switch from storage to modem manually, so I connected to it using HyperTerminal in Windows and executed the command "AT+ZCDRUN=8".  I plugged it back into the pfSense computer and it does see it as a modem now.  I was able to set my PPP config using cuau0.2 as the interface, but I get the same error as ldtech describes above.  Here's a snippet from my PPP log:

      Oct 20 21:39:00 ppp: [wan_link0] ACFCOMP

      Everything seems to go wrong at the line Oct 20 21:39:00    ppp: [wan] can't config [c]:: Invalid argument

      Subsequent reconnection attempts get only this in the PPP log:

      Oct 20 21:31:27 ppp: [wan_link0] Link: reconnection attempt 10 in 3 seconds
      Oct 20 21:31:30 ppp: [wan_link0] Link: reconnection attempt 10

      Oct 20 21:31:30 ppp: [wan_link0] Link: DOWN event
      Oct 20 21:31:30 ppp: [wan_link0] LCP: Down event

      Anyone know what this means?  Or have any direction of where I should begin troubleshooting?

        Update

        Downloaded the latest beta snapshot (20101020) and I'm still getting an error at the same point but slightly different:

        ppp: [wan] can't config [19]:: Invalid argument

          Can you get /var/etc/mpd_*.conf

            Ok. tried again with snapshot 20101024.

            Here is the /var/etc/mpd_wan.conf:

            startup:

            configure the console

            set console close

            configure the web server

            set web close

            default:
            pppclient:
            create bundle static wan
            set iface name ppp1
            set iface route default
            set iface disable on-demand
            set iface idle 0
            set iface enable tcpmssfix
            set iface up-script /usr/local/sbin/ppp-linkup
            set iface down-script /usr/local/sbin/ppp-linkdown
            set ipcp ranges 0.0.0.0/0 10.64.64.0/0
            set ipcp enable req-pri-dns
            set ipcp enable req-sec-dns
            #log -bund -ccp -chat -iface -ipcp -lcp -link

            create link static wan_link0 modem
            set link action bundle wan
            set link disable multilink
            set link keep-alive 10 60
            set link max-redial 0
            set link disable chap pap
            set link accept chap pap eap
            set link disable incoming
            set link mtu 1492
            set auth authname "wapuser1"
            set auth password wap
            set modem device /dev/cuaU0.2
            set modem script DialPeer
            set modem idle-script Ringback
            set modem watch -cd
            set modem var $DialPrefix "DT"
            set modem var $Telephone "*99#"
            set modem var $APN "isp.apn"
            set modem var $APNum "1"
            open

            I still get the "ppp: [wan] can't config [c]:: Invalid argument", this time I also got another variation "ppp: [wan] can't config [33]:: Invalid argument".

                This problem still exist in RC1 (i386-20110226-1429).

                I also noted that when trying to use two USB 3G modems only one connects, the other gets USB_ERR_TIMEOUT.

                RC1 is clearly not ready for production.

                  I also have the same problem with my Huawei 3g module.

                  Is there a way to set the PPP debug level to MAX?

                  pppd.log

                      Please read this post about the MPD binary.
                      Maybe some files are outdated?

                        This affects the new Huawei e398 LTE modem as well.

                        Relevant line reads:

                        ppp: [wan] can't config [1c]:: Invalid argument

                          OK, Problem solved!!

                          See http://sourceforge.net/projects/mpd/forums/forum/44693/topic/4516341

                          Changed NG_PPP_MAX_BANDWIDTH in ng_ppp.h kernel file to a much higer value. The big BPS number of the K4505 Huawei modem is confusing the bandwidth maximum.

                          
                          /* Max allowable link latency (miliseconds) and bandwidth (bytes/second/10) */
                          #define NG_PPP_MAX_LATENCY      1000            /* 1 second */
                          #define NG_PPP_MAX_BANDWIDTH    125000          /* 10 Mbits / second */
                          
                          

                          a MPD developer is changing the source of MPD5 now, so maybe update PFsense with the new MPD code in the future??

                            Imported the fix done on mpd5 sources in pfSense.

                              Does the Huawei E398 work with RC3 or what's the status? I'm having some trouble getting go grips with if it works or not. Some people are having trouble with usb_modeswitch and for some other it works.

                              Could someone enlighten me?

                                The e398 works with the RC3. I use it on a laptop based home router an it serves well. (Thanks to ermal for the commit and GrandmasterB for the info). You may have to set it to 4G only on a Win PC first as I am uncertain if Linux and FreeBSD can set that parameter or how it will behave if set to auto.

                                The only issues I encounter in experimenting occur - or so I think  for now - if other USB interfaces are activated. In my setup a reboot with an USB ethernet adapter and wireless adapter alongside the e398 - all with previously successfully assigned interfaces - saw an "interface mismatch" message and the interface assignment routine started. Removing and replacing the devices in some or other sequence saw the old assignments be picked up and the bootup completed. My impression is this is a usb-modeswitch issue with the e398 but more needs to be done to isolate what triggers it.
