USB Modem detected - but not showing under Interfaces?

wallabybob

The recent snapshot of pfSense that I downloaded is missing a few components (kgdb and kernel symbols) I hoped to use in the procedure to see if Zani's modem would work with the u3g driver. So here's a way of testing the theory with a standard FreeBSD 8.1:

(if necessary) install FreeBSD 8.1
Boot FreeBSD 8.1 without the modem plugged in.
Login as root and type the bold parts of the following:

kgdb -w /boot/kernel/kernel /dev/mem

1850 cpuid = PCPU_GET(cpuid);
(kgdb) p/x u3g_devs[0]
$1 = {driver_info = 0x0, idVendor = 0x4a5, idProduct = 0x4068, bcdDevice_lo = 0x0, bcdDevice_hi = 0x0, bDeviceClass = 0x0,
bDeviceSubClass = 0x0, bDeviceProtocol = 0x0, bInterfaceClass = 0x0, bInterfaceSubClass = 0x0, bInterfaceProtocol = 0x0,
match_flag_vendor = 0x1, match_flag_product = 0x1, match_flag_dev_lo = 0x0, match_flag_dev_hi = 0x0,
match_flag_dev_class = 0x0, match_flag_dev_subclass = 0x0, match_flag_dev_protocol = 0x0, match_flag_int_class = 0x0,
match_flag_int_subclass = 0x0, match_flag_int_protocol = 0x0, match_flags = 0x0}
(kgdb) set u3g_devs[0].idVendor = 0x1d09
(kgdb) set u3g_devs[0].idProduct = 0x4000
(kgdb) p/x u3g_devs[0]
$2 = {driver_info = 0x0, idVendor = 0x1d09, idProduct = 0x4000, bcdDevice_lo = 0x0, bcdDevice_hi = 0x0, bDeviceClass = 0x0,
bDeviceSubClass = 0x0, bDeviceProtocol = 0x0, bInterfaceClass = 0x0, bInterfaceSubClass = 0x0, bInterfaceProtocol = 0x0,
match_flag_vendor = 0x1, match_flag_product = 0x1, match_flag_dev_lo = 0x0, match_flag_dev_hi = 0x0,
match_flag_dev_class = 0x0, match_flag_dev_subclass = 0x0, match_flag_dev_protocol = 0x0, match_flag_int_class = 0x0,
match_flag_int_subclass = 0x0, match_flag_int_protocol = 0x0, match_flags = 0x0}
(kgdb) quit

This changes an entry in the u3g driver's table of devices it recognises so it will recognise the Neotel modem.

Plug in the modem. On the console the system should report a u3g device.
Configure and attempt to use the u3g interface. I'm hoping to get a 3G modem later this week. I may be able to provide more configuration details later ths week or early next week.

If the modem works with the (slightly modified) u3g driver you can submit a problem report to the FreeBSD developers to get the corresponding change into the source code and work on the pfSense developers to get it into pfSense.

Download the file from here.
http://www.mediafire.com/?bcsv0efbdq3boyx

Put it in /boot/kernel on the pfSense install and reboot.
Is your modem detected after rebooting?

This is patched kernel with your ids.

Zani

Thanks so far Wallabybob: :)

I have to download FreeBSD 8.1 -
The # kgdb -w /boot/kernel/kernel /dev/mem was not recocnized by PfSense.

So I tried Ermal's [thanks!]kernel file - with no luck so far.

Ermal, I need to understand this kernel file - did you put the missing components in there?

My next step is to download FreeBSD8.1 - this can take a while…

PS

;D IT SEEMS I WAS NOT LOOKING PROPERLY - SEE DOWN BELOW! ;D
AND ERMAL - WHAT DID YOU DO! :D - We need to know! Just the ID's? How?
And is the future kernel going to have it?

eri--

Zani tell me if this device appears as a umass first or not?!

Its quite difficult without haveing a device locally, actually.

Zani

No USB Mass Storage Device that I can see at a glance - but - how do I test for one?

Perry

dmesg | grep umass

Zani

Thanks Perry; dmesg | grep umass gives no results, dmesg gives:

I obviously have it on the slow port….

I suddenly can see
/dev/cuaU0.0
/dev/cuaU0.1
under link interfaces in PPPs under Interfaces! ;D

I don't know how I missed it earlier - SEE ABOVE. [Maybe I only looked under PPPoE]
Ill let you know if it works properly!
Neotel is not listed as a service provider - all the others [cellphones] are there..</hid></hid></vendor></sis></sis></sis></sis></sis></sis>

Still setting it up, got both ports connected, bridged them, can disconnect one at a time, but still no traffic through.
Still fiddling and trying to get the right info to read - not so easy to find…... ???

Zani

The Question is: should the modems 2 ports be bridged? ???

wallabybob

@Zani:

The Question is: should the modems 2 ports be bridged? ???

Probably not, but it depends on what you are trying to do. And bridged to what? And which two ports? (I have the impression that some 3G modems have one 'port' for data and another 'port' for control functions and/or reporting. I can't say about your modem. But almost certainly you wouldn't want to bridge a 'reporting port' to anything else. )

Zani

Wallabybob,
I contacted the USB driver writers at FreeBSD with all the needed info:
Hans Petter Selasky & Nick Hibma
But we still need someone to explain the whole process for the uninformed.
You were going to get a 3g modem - please write us your process to get the modem driver adapted.
My goal still is to get everybody to be able to do this.

Zani

Ermal if you could share the patch - we would be grateful - especially if you could share the "how to"

wallabybob

@Zani:

But we still need someone to explain the whole process for the uninformed.
You were going to get a 3g modem - please write us your process to get the modem driver adapted.

Please elaborate on what you mean by the whole process.

I ordered a 3G modem online early Monday morning. It was going to be delivered Tuesday. By mid Thursday it hadn't appeared so I called and was told it would be delivered Friday. Its now late Friday evening and it still hasn't been delivered.

I suspect its a bit premature to "get the modem driver adapted". You haven't provided any evidence yet that its performing properly.

Zani

No, I could not get it to connect again - status interfaces , connect [ Neotel (ppp0) or (ppp1) ]

Something I have not mentioned - this is dual wan, the one connection goes through Telkom, the first operator via ethernet connection. Neotel is SA's second operator.
I set up Routing - the gateways Neotel & Telkom - Telkom as defaulted as default, Groups with both as tier 1
autodial is selected on Neotel… and status still down.
I now set Telkom as Tier2 & made sure the Firewall rules see the gateway as the Gateway Group I made with Telkom & Neotel A+B ports.
But I am still writing this via Telkom….

gnhb

Zani,
maybe back up your config and reset to defaults, and then start with a simple single connection through the Neotel to make sure your 3G connection is working.

Zani

Ill try this…. ;)

You need only ONE of the two cuaUx.x ports for Data. The other one is to access the modem for management purposes. You'll have to try them both to see which works.

Or, you can use the "tip" program on the pfSense box in conjunction with the /etc/remote file to talk to the ports via the command line. The AT command set for 3G modems is public on the net, so you can see which commands to send to the ports to test for which port is the one for data.

If you decide to do this, the /etc/remote file looks like this at the end of the file:

ucom5:dv=/dev/cuaU4:br#9600:pa=none:
ucom6:dv=/dev/cuaU5:br#9600:pa=none:
ucom7:dv=/dev/cuaU6:br#9600:pa=none:
ucom8:dv=/dev/cuaU7:br#9600:pa=none:

Just add two lines to the file that look like this:
neo1:dv=/dev/cuaU0.0:br#9600:pa=none:
neo2:dv=/dev/cuaU0.1:br#9600:pa=none:

then at the command prompt type
tip neo1
OR
tip neo2

and you'll be talking directly to the modem.

type AT to the modem and you should get "OK" back on either port.
type ATI or (ati) and see the modem manufacturer and model info, etc.
type at+csq to see the radio signal strength.

also . . .

~^D or ~.
Drop the connection to the modem and exit.

I'm on OS X and the ~. sequence exits my pfSense connection, but the ~^D just exits the tip program.

pfSense should automatically detect which is the data port for you on latest snapshots.

For the @freebsd.org devs, which i am part of too, i will update them as soon as you prove that it is working correctly.

Zani

Hi, I had great difficulty to log onto this forum the last few days. Ill do as you say. Thanks all!

Zani

My internet connectivity is limited. So i am way behind in my posts :-[

Nick Habema sent me a "neotel_prime.usb.diff" file to try.
How do I apply it? ???
