New 3g usb stick not supported - how to add support ?

Fennel

Hi,

My existing Huwaei 3g stick works fine in 2.0, though I had to patch the rrd graphs to get signal levels.

I have a new model Huwaei k4505 (20mbps hspa+ ) that I would imagine will work fine, but the vendor/model id's are not known to pfsense.

How do I add them to pfsense to take this a step further ? is it a recompile of the kernel module ?

Thanks !

For now yes.
For 2.1 we might consider some tools provided in FreeBSD 9 to make this without recompiling

Is this as 'simple' as take a stock freebsd 8 and recompile the module, make sure it works, then insert that into my pfsense image ?which is probably documented somewhere here.

Nope.
You have to build a pfSense kernel with those changes.
Search the devwiki for instrunctions.

ok, that was made more painful by a usb bug under vmware :-(

making a new kernel under virtualbox with the new modem attached worked

output from```
screen /dev/cuaU0.0

AT
OK
ATI5
Manufacturer: Vodafone (Huawei)
Model: K4505
Revision: 11.828.03.01.11
IMEI: xxxxxx <- I changed this
+GCAP: +CGSM,+DS,+ES

OK


So looks good

added```
U3G_DEV(HUAWEI, K4505, U3GINIT_HUAWEI),

```to /usr/src/sys/dev/usb/serial/u3g.c

and```
product HUAWEI K4505		0x1464	3G modem

```to /usr/src/sys/dev/usb/usbdevs

so , now just to add it to pfsense, which, by the way, you have done an excellent job of making into a sane task !

I hacked your script for signal strength to look like this btw, as 3gstat binary didn't work, using an if statement of

3gmodel=usbconfig -d $dev dump_device_desc | grep id | cut -f2 -d "=" | xargs

if [ "$3gmodel" = "0x12d1 0x1464" ]; then


The 'hack was'

/usr/bin/nice -n20 /usr/local/bin/rrdtool update /var/db/rrd/ppp-cellular.rrd N: ( sleep 1; echo "AT+CSQ" > /dev/cuaU0.2 ) | head -n16 /dev/cuaU0.2 | grep -m1 CSQ | cut -d',' -f1 | cut -d ':' -f2 | xargs -I {} echo "{} * 2 -113" | bc:U


instead of```

if [ -n "$dev" ]; then /usr/bin/nice -n20 /usr/local/bin/rrdtool update /var/db/rrd/ppp-cellular.rrd N:`3gstat -s -d $dev`

I did the same.

Added a line to 'usbdevs' and a line to 'u3g.c', compiled the PFsense kernel and installed it on my box.
But the Huawei K4505 will only see 2 disks (1 CDrom and 1 flashdisk). No serial ports what so ever.

Are you sure these are the only changes you made to enable youre K4505 on PFsense?

thanks,
