Default Tryin' to use ZTE 3G Dongle in FreeBSD8

Hello all.
I've been trying to get working the 3G dongle ZTE626 for internet access in FreeBSD 8, up to now, without success. I'm quite new to BSDs.

I did the following.

1.1) Tested in linux (Debian Squeezy) using usb_modeswitch to switch the device to modem function. Tested the result with lsusb Switched to Modem ... [OK]

1.2) Tested the device with minicom to send some AT command ... [OK]

1.3) Connected to Internt with wvdial ... Internet communications ... [OK]

In linux after switching to modem function the device is attached to a node /dev/ttyUSB2. Thats the comm. port I used in wvdial and minicom.

2) FreeBSD8

2.1) I compiled usb_modeswitch. And switched to modem function. Seemed to have switched to modem ... [OK]

# usbconfig dump_device_desc

ugen2.2: <ZTE Configuration ZTE,Incorporated> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON

  bLength = 0x0012
  bDescriptorType = 0x0001
  bcdUSB = 0x0200
  bDeviceClass = 0x0000
  bDeviceSubClass = 0x0000
  bDeviceProtocol = 0x0000
  bMaxPacketSize0 = 0x0040
  idVendor = 0x19d2
  idProduct = 0x0031
  bcdDevice = 0x0000
}  iManufacturer = 0x0002  <ZTE,Incorporated>
  iProduct = 0x0001  <ZTE Configuration>
  iSerialNumber = 0x0003  <P671A2PERD010000>
  bNumConfigurations = 0x0001
I mean seemed to work because idVendor and idProduct are the same as linux's lsusb in modem function.

2.2) What node the device is attached? ... [FAILED]

I think the problem is here... I don't know if the device is beeing recognized. I use u3g driver, I put it in loader.conf

I tried minicom in /dev/ttycuau0 without response from modem. I think that node is not linked to this dongle.

An interesting message I get in /var/log/message is the following:

root: Unknown USB device: vendor 0x19d2 product 0x0031 bus uhub2
Those are really idVendor and idProduct of this device.

Am I missing some step?
Does anybody knows if is there any other approach I could try?
Is there anything else I could try before giving up?

Thanks in advance,
