I can.
Camera working fine; tail -f /var/log/syslog
...
press F9

so the kernel notices that the camera drops off the USB bus. Nothing
else is printed.
xev did, at this point, detect the keypress as well:

I then press F9 again. (Note: it's not really F9. It is the camera key. If I
press Fn + CameraKey, I get F9.) Syslog shows:
