I'm playing with the built-in camera of my laptop.

Using usbconfig, if I issue a power_off and then a power_on on the
device, I don't have any ugen device attached.

Is it normal?

# usbconfig -u 6 -a 2 dump_device_desc
ugen6.2: <Built-in iSight Apple Inc.> at usbus6, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=ON

  bLength = 0x0012 
  bDescriptorType = 0x0001 
  bcdUSB = 0x0200 
  bDeviceClass = 0x00ef 
  bDeviceSubClass = 0x0002 
  bDeviceProtocol = 0x0001 
  bMaxPacketSize0 = 0x0040 
  idVendor = 0x05ac 
  idProduct = 0x8502 
  bcdDevice = 0x0155 
  iManufacturer = 0x0001  <Apple Inc.>
  iProduct = 0x0002  <Built-in iSight>
  iSerialNumber = 0x0003  <9063CC366CC23E8C (03.00)>
  bNumConfigurations = 0x0001 

# usbconfig -u 6 -a 2 power_off
devd =>
!system=DEVFS subsystem=CDEV type=DESTROY cdev=usb/6.2.2
!system=DEVFS subsystem=CDEV type=DESTROY cdev=usb/6.2.1

# usbconfig -u 6 -a 2 power_on
? at bus=1 hubaddr=4 port=6 devaddr=2 interface=0 vendor=0x05ac
product=0x8502 devclass=0xef devsubclass=0x02 sernum="9063CC366CC23E8C
(03.00)" release=0x0155 intclass=0x0e intsubclass=0x01 on uhub6

and in the console:
Unknown USB device: vendor 0x05ac product 0x8502 bus uhub6

When I boot the laptop ugen6.2 is attached and works fine with webcamd.

Thanks, regards.
