General Information

First of all, almost all of 3G modem in the market have a "Zero-CD" mode that will automaticaly install a driver when plug in to windows based os, so by default when we plug it in to our freebsd system, it will go to "Zero-CD" mode. We need to change this mode to a "Modem" mode in order to use it in our freebsd system.

There are two ways to do this, either using camcontrol+devd or usb_modeswitch. I use camcontrol+devd method as by default it already in the system.

So, while listening to your 8 GB china brand mp3 player or your Apple iphone or ipod, or some of you that have a super duper high output amp stereo hifi with a very big speaker that can blow out your entire neighborhood house, let's get started!

Requirements

1. Server/PC/Laptop with FreeBSD 7.2 with u3g module loaded.
   
2. 3G HSDPA/UMTS usb/card  or 3G capable phone that supported by FreeBSD/u3g.
   
3. Apple iPod/iPhone (trademark to Apple Inc) or a China brand (or no-brand) mp3 player. - This is optional.
   
4. Working 3G internet access.
   
5. This Guide (duhhh...).

Configuration

Freebsd 7.2 has include u3g driver in it, so we are going to use that driver, load up the driver in /boot/loader.conf or compile it into the kernel, so ask your wife or your house cleaning maid for a choice :). My modem detected as umass0, some of the modem detected as ugen0 so load which that are detected.

u3g_load="YES" umass_load="YES"

Then reboot if you want or load it up using kldstat.
Plugin you modem to your system and use usbdevs command to see your modem details, you will need to search which one of the lines are your modem belongs.

#	usbdevs -v

mine was :

port 1 addr 3: full speed, power 100 mA, config 1, USB MMC Storage(0x1000), Qualcomm, Incorporated(0x05c6), rev 0.00

In this line, we need to get the id for vendor and product, so mine was vendor = 0x05c6 and product = 0x1000. Next use camcontrol devlist command.

# camcontrol devlist <Option ICON 2.31> at scbus1 target 0 lun 0 (da1,pass1)

So my modem detected as Option ICON 2.31, in the last part of the line was (da1,pass1), we need to use the "Option" and "pass1" value.  Create a folder in /etc namd devd, /etc/devd, in this folder create any file name, I'm using option.conf same with my modem, vodafone option globesuffer icon.

In the option.conf file, put this:

attach 100 { match "device-name" "umass[0-9]+"; match "vendor" "0x05c6"; match "product" "0x1000"; match "devclass" "0x00"; action "sleep 3; /sbin/camcontrol cmd `/sbin/camcontrol devlist | /usr/bin/grep Option | /usr/bin/awk '{match($10, /pass[0-9]+/); print substr($10, RSTART, RLENGTH) }'` -c '01 00 00 00 00 00' -i 1 i1 > /dev/null"; };

Next, be warn, some of you might be needing master yoda training to help you on this :) just kidding.. move on..
Replace vendor and product with the id or your modem.  In the action line, you will need to edit a few things:

/usr/bin/grep Option <- replace with the output of your camcontrol devlist before, mine was Option.

$10 <- $10 is the value of the 10th result from the camconrol devlist line, mine has pass1 value remember?

example:

<Option ICON 2.31> at scbus1 target 0 lun 0 (da1,pass1) $1 = <Option $2 = ICON   $3 = 2.31> $4 = at $5 = scbus1 $6 = target $7 = 0 $8 = lun $9 = 0 $10 = (da1,pass1) /pass[0-9]+/ <- replace with your camcontrol devlist last value, if it was cd1 then it will be /cd[0-9]+/

Save the option.conf file.  Plug out your modem and run /etc/rd.d/devd restart to reload new conf for devd.

/etc/rc.d/devd restart Stopping devd. Starting devd.

Now, plug back your modem and if everything fine, they will be a message like this:
[/output]umass1: detached
ucom0: <Option N.V. Fusion UMTS Quad-GPRS, class 0/0, rev 1.10/0.01, addr 2> on uhub2
ucom0: configured 3 serial ports (U0.%d)[/output]
This was still buggy I think, some of you might not have any message at all, try to plug in and out a few times.  You can also do manual switch without using devd:

# camcontrol devlist <Option ICON 2.31> at scbus1 target 0 lun 0 (da1,pass1) # camcontrol cmd pass1 -c "01 00 00 00 00 00" -i 1 i1

So if everything working, ucom0 already up, then /dev/cuaU0.0 will be created by u3g, if you are using ubsa, then /dev/cuaU0 will be created.  We are going to use /dev/cuaU0.0 in ppp.conf.

This is the sample of ppp.conf for Malaysia Celcom 3G ISP, you can use it as a birthday present for your wife, I don't mind :)

That's all, enjoy taking over the world.. erkk I mean surfing the world wide web. :)

sorry this dont work for me i am using PCBSD 7.1.1 which uses freeBSD 7.2  u3g load="yes" given as per the instruction when i use camcontrol devlist it shows my Cd drive no sign of my huawei 3g modem so i cannot proceed beyond that Sorry expecting another guide  for configuring Huawei EC 325 3g usb  modem
