Core dumps
On Linux, enable core dumps before starting uhub:
% ulimit -c unlimited
% uhub
If uhub crashes, a file called "core" will be written to disk, and this can be used to debug the problem further. Please compress the core file AND the uhub binary.
tar czvf coredump.tar.gz uhub core
In that case please file a bug report and attach coredump.tar.gz in the bug tracker.
