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

[David Wolfskill]

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
webcam:

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 

g1-254(10.1-S)[81] 

I have installed:
g1-254(10.1-S)[81] pkg info webcam\* cuse4bsd\* v4\* pwcview\*
webcamd-3.18.0.1
cuse4bsd-kmod-0.1.36
v4l_compat-1.0.20120501_1
pwcview-1.4.1_6
g1-254(10.1-S)[82] 

This is running on:
g1-254(10.1-S)[82] uname -a
FreeBSD g1-254.catwhisker.org 10.1-STABLE FreeBSD 10.1-STABLE #29  r281195M/281199:1001512: Tue Apr  7 04:25:29 PDT 2015     root at g1-254.catwhisker.org:/common/S1/obj/usr/src/sys/CANARY  i386
g1-254(10.1-S)[83] 

I have loaded the cuse4bsd kernel module:

g1-254(10.1-S)[83] kldstat

g1-254(10.1-S)[84] 

devd is running:

g1-254(10.1-S)[84] service devd status
devd is running as pid 36061.
g1-254(10.1-S)[85] 

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 $?
0
g1-254(10.1-S)[89] service webcamd status
webcamd is not running.
g1-254(10.1-S)[90] 


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?

Thanks!

Peace,
david
