Thank you for the answer!
Yes, I can download pictures without additional power on Windows and
Linux, so this does not seem to be the problem.
Yes the device uses the PTP protocol. I do not expect it to appear as
umass. But: I want to see it as ugen, so that higher level programs can
access it. On L****x I am using jPhoto (a java program using libusb) to
access the camera via PTP. And now I have read that recent versions of
gphoto2 have PTP support too. But unfortunately our USB support drops
the device totally, so I am stuck here. (Any yes I have, for obvious
reasons, not yet tested if these programs work on FreeBSD)
