Hello,
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

bDeviceSubClass = 0x0002
bDeviceProtocol = 0x0001

# usbconfig -u 6 -a 2 power_off
devd =>

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.
