Trying to get a built-in webcam (Dell M4800 laptop) to work -- clues?

I recently retired a Dell M4400 laptop (that served well for about 7
years); its replacement is a Dell M4800... which came with a built-in

g1-254(10.1-S)[80] usbconfig -d 1.3 dump_device_desc                            
ugen1.3: <LaptopIntegratedWebcamHD CN0767N972487515BSJWA01> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

  bLength = 0x0012 
  bDescriptorType = 0x0001 
  bcdUSB = 0x0200 
  bDeviceClass = 0x00ef  <Miscellaneous device>
  bDeviceSubClass = 0x0002 
  bDeviceProtocol = 0x0001 
  bMaxPacketSize0 = 0x0040 
  idVendor = 0x0c45 
  idProduct = 0x64d0 
  bcdDevice = 0x4214 
  iManufacturer = 0x0002  <CN0767N972487515BSJWA01>
  iProduct = 0x0001  <Laptop_Integrated_Webcam_HD>
  iSerialNumber = 0x0000  <no string>
  bNumConfigurations = 0x0001 


I have installed:
g1-254(10.1-S)[81] pkg info webcam\* cuse4bsd\* v4\* pwcview\*

This is running on:
g1-254(10.1-S)[82] uname -a
FreeBSD 10.1-STABLE FreeBSD 10.1-STABLE #29  r281195M/281199:1001512: Tue Apr  7 04:25:29 PDT 2015     root at  i386

I have loaded the cuse4bsd kernel module:

g1-254(10.1-S)[83] kldstat 
Id Refs Address    Size     Name
 1   31 0xc0400000 12b8ac8  kernel

11    1 0xd1fd6000 7000     cuse4bsd.ko

devd is running:

g1-254(10.1-S)[84] service devd status
devd is running as pid 36061.

An attempt to just fire up webcamd doesn't actually seem to be useful:

g1-254(10.1-S)[86] service webcamd status
webcamd is not running.
g1-254(10.1-S)[87] service webcamd forcestart
Starting webcamd.
g1-254(10.1-S)[88] echo $?
g1-254(10.1-S)[89] service webcamd status
webcamd is not running.

Getting webcamd to work isn't the most critical thing in the world,
but it would be kinda nice.

Any hints or clues for doing this?
