This happens intermittently on my Macbook Pro 5.5, so I debugged into
this for a while. And found there is an incorrect free due to the memory
not being zero-ed during allocation. The attached patch tries to fix
this issue (at least it worked on my side). And I've yet built the
libusb packages at:
http://people.canonical.com/~ycmiao/lp427805/libusb-0.1-4_0.1.12-14~lp427805_amd64.deb.
Please test and report back.
