As a test I can't see why not. I've never tried that myself though...

it didn’t work..I think there’s no ncm kernel module for 0x12d1 Sub=03 Prot=16..

Is there any possibility I can recompile and patch this cdc driver?

You can try it in a FreeBSD 10.3 box. I have done so with other drivers and loaded them as kernel modules.

I've never seen it done with a USB device though.

If you dont mind can you guide me , I already made an svn checkout on 10.3 , no idea how to apply the patch,and if I compile it succcessfully , I can donate a little some beers..

Basically as I described here: https://forum.netgate.com/post/712896

But obviously not for urndis as was that case.

I applied the patch and compiled it..test the driver on vm freebsd 10.3 and it was detected and ue0 interface came up..but when I use this driver on pfsense ,, still same issue .. Do I need more drivers to be copy to pfsense?

stephenw10

Maybe. You compiled just the cdce module in FreeBSD?

Maybe it didn't load as expected in pfSense? You have to load it at boot time to replace the in kernel driver.

yup only the cdce driver..I add this line if_cdce_load="YES" on boot/loader.conf and copy the compiled driver at boot/kernel..I can see the message that it is loaded on boot

Loading /boot/defaults/loader.conf
/boot/kernel/kernel text=0x122025a data=0x84738c+0xd9688 syms=[0x4+0xf3aa0+0x4+0                                                                                        x16b822]
/boot/kernel/if_cdce.ko text=0x35e0 data=0x164+0x4 syms=[0x4+0x920+0x4+0x9ff]

and to be sure , I fresh install 10.3 , imported the compiled driver,and eu0 interface came up..but not with pfsense

stephenw10

Hmm, well something is different there then.

You could check what we were using at that time which I believe is here: https://github.com/pfsense/FreeBSD-src/tree/RELENG_2_3

@jly2680 unfortunately no.

On other client sites I've used a netgear nighthawk in bridge mode for this and it's a solid solution... although for that to work you need to make pfsense override the subnet mask the dhcp passthrough from the nighthawk issues, it issues a /32 and needs to be changed to a /24 otherwise it can't contact the default gateway to actually get traffic out. To do this you need to add "supersede subnet-mask 255.255.255.0" to the "DHCP Option Modifiers" under the "Lease Requirements and Requests" portion of your interface connected to the nighthawk.

I follow your suggestion but with e3372 plug at ddwrt (ncm-wwan interface bridge with wan port vlan 2 ) bridge with pfsense interface. pfsense as a dhcp client to 4g interface of ddwrt and it will pick up ISP IP which will avoid double nat issue .works pretty solid too..

Hope it does end well..

While this is an old topic, for anyone struggling to get Huawei modem to connect in CDC ECM mode using NDISUP command, the problem is it will ignore those commands sent to cuX serial devices. They need to be sent using the WDM interface, which Linux exposes as cdc-wdmX, but FreeBSD does not.

A workaround is to use a usbconfig command and send that command directly to the device. I explained my findings here: https://dawidwrobel.com/journal/initializing-lte-modem-using-raw-usb-communication/
