Moving away /lib/udev/rules.d/95-devkit-disks.rules leads the Harddrive to show up.
It appears in /media under the name "4777707B117F74F2".

Running

a) sudo skdump /dev/sdb ejects the harddrive and tells me: Failed to open disk /dev/sdb: Invalid argument
b) sudo skdump jmicron:/dev/sdb ejects the harddrive and tells me: Failed to open disk jmicron:/dev/sdb: No such device

The out put of sudo strace -vv -s 1024 -o /tmp/trace skdump /dev/sdb is attached.

Thanks, Stefan. So these traces do look exactly the same as in bug 387161. It seems that in the middle of the bug there was some confusion, and this is a duplicate after all. I forwarded your traces to the upstream bug, thanks for getting them!
