We tried to read the EFI partition data. That kills some devices if they also report the size wrong (eg the ipod mini). You'll probably find that with a custom kernel it matters whether you have EFI partitioning on or off. If so let me know - it needs a USB quirk entry.



The stock FC3 kernel has the EFI_PARTITION enabled (not sure why - the help for this item suggests that it is only useful on an IA-64, which my machine is not...).

I built a stock 2.6.9 kernel, and disabled the EFI_PARTITION (and nothing else). With this kernel, I can mount the camera and modify the contents of the mounted fs. The camera is not automounted, however...

If there are other tests that you would like me to conduct, please let me know. I won't be able to get to them until next weekend, though..

Thanks for the help to date!
