u3g and Vodafone k3772 (not k3772z)

Hi!

I borrowed a Vodafone - Huawei K3772 Mobile stick for some days. It's a 
bit disappointing, that I could not use it under FreeBSD.
This 3g modem is made by Huawei (the K3772z is made by ZTE) with 
vendorID: 0x12d1 and productID: 0x1526.

# usbconfig -d 4.3 dump_device_desc
ugen4.3: <Vodafone Mobile Broadband Huawei Vodafone Huawei> at usbus4, 
cfg=255 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

   bLength = 0x0012
   bDescriptorType = 0x0001
   bcdUSB = 0x0200
   bDeviceClass = 0x0000
   bDeviceSubClass = 0x0000
   bDeviceProtocol = 0x0000
   bMaxPacketSize0 = 0x0040
   idVendor = 0x12d1
   idProduct = 0x1526
   bcdDevice = 0x0102
   iManufacturer = 0x0002  <Vodafone (Huawei)>
   iProduct = 0x0001  <Vodafone Mobile Broadband (Huawei)>
   iSerialNumber = 0x0000  <no string>
   bNumConfigurations = 0x0001

I tried to switch it to USB-modem mode, but none of the usb_quirks 
worked. And with EJECT_HUAWEI, I got an error, too.

# usbconfig -d ugen4.3 add_quirk UQ_MSC_EJECT_HUAWEI
Adding quirk 'UQ_MSC_EJECT_HUAWEI' failed, continuing.

Under Linux, with usb_modeswitch, I could switch it to modem, with the 
MessageContent="55534243123456780000000000000011062000000100000000000000000000"
string, and after it, it will be Vendor=12d1 ProdID=14cf. There are 
some interesting information about this modem in this forum thread:

Is it possible, to use this modem under FreeBSD? And if yes, how?

Thanks,
