>Description:
Mounting the camera doesn't work, synchronize cache error appears in the message log. This seems to be a quirk that needs to be added (wasn't necessary in 7.2 btw, where the camera worked fine).

>How-To-Repeat:
Mount Fuji 2600Z camera.

>Fix:
Patch for umass.c:

Note that with this patch, I can mount the camera about 15 seconds after switching the camera on. In FreeBSD 7.2 it was instantaneous. Why is this? Is there a fix?
