Hi all,
I am trying to get a "Vodafone/Huawei K3770" working on FreeBSD 8.2.
When I insert the modem, I find only 2 USB files for it under /dev/usb.
# usbconfig -u 7 -a 2 dump_device_desc
ugen7.2: <Vodafone Mobile Broadband (Huawei) HUAWEI> at usbus7, cfg=0
md=HOST spd=HIGH (480Mbps) pwr=ON
bLength = 0x0012
bDescriptorType = 0x0001
bcdUSB = 0x0200
bDeviceClass = 0x0000
bDeviceSubClass = 0x0000
bDeviceProtocol = 0x0000
bMaxPacketSize0 = 0x0040
idVendor = 0x12d1
idProduct = 0x14d1
bcdDevice = 0x0102
iManufacturer = 0x0002 <HUAWEI>
iProduct = 0x0001 <Vodafone Mobile Broadband (Huawei)>
iSerialNumber = 0x0000 <no string>
bNumConfigurations = 0x0001
# file /dev/usb/7.2*
/dev/usb/7.2.0: character special
/dev/usb/7.2.15: character special
I am using usb_modeswitch to activate the modem.
# usb_modeswitch -v 0x12d1 -p 0x14d1 -c 12d1\:14d1

After I issue the command, I could see more devices added to /dev/usb
and the Product ID changes accordingly.

After that I did dmesg, but I see the device to be detected as a umass
storage.
# dmesg | tail

I found out that under linux the "usbserial" module is unloaded then
loaded using:
# modprobe usbserial vendor=0x12d1 product=0x14c9
But I don't know how to do that under FreeBSD.
I have no clue what to do, and any help is very much appreciated.
