There's a couple of experiments you can do which should help make things more clear. First, turn on the usb-storage verbose debugging option in the kernel configuration. Then try plugging in the camera and post the output from dmesg, showing the debugging messages. (Post it to the linux-usb-devel mailing list as well as to me or Phil.) Try doing this: without your unusual_devs entry, with the unusual_devs entry, and with the unusual_devs entry but with the FIX_INQUIRY flag removed.
