Not a bug. OS vendors are allowed to stop shipping outdated libraries, and
that version of libusb is ancient.

Again, not a bug, recent Linux distros have started to package libraries in
You'll need to update your packages based on OS version, the same as you do
for your Windows drivers. Though, another solution to the problem would be
