I can confirm this problem.
I could fix it by replacing my /lib/x86_64-linux-gnu/libusb-1.0.so.0.1.0
with the version libusb-1.0-0_1.0.9~rc3-2ubuntu1 (probably a newer version
would also work, I just could not
find one).
The version which did NOT work:
apt-cache policy libusb-1.0-0
libusb-1.0-0:
Installed: 2:1.0.17-1ubuntu2
