[PC-BSD Support] Cannot setup CANON PowerShot A450

[Max ID]

Hi everybody. I'm running PC-BSD 7 Alpha, and I would like to setup
CANON PowerShot A450
digital camera. I plugged it in (USB), saw the message
ugen0: <Canon Inc. Canon Digital Camera, class 0/0 ...............     on uhub2

Then I opened KDE Control module Advanced tab and added my camera
model to the list
But nothing happened. When I double-click the icon with camera, the
following message appears:
   Bad parameter.

What do I do incorrectly ? Thanks forward.
