I can't remove libusb-1.0-0 package which provides libusb-1.0.so.0
because 93 packages depend on it including gdm3, gnome, cups and many
others and that would render jessie practically useless. The version
required by jessie is given as 2:1.0.19-1:amd64 and this is what is
installed. So the symlink works.
libudev0 package is not in jessie, only wheezy. jessie has libudev1.
The other missing library was reported as :
linux-vdso.so.1
objdump: 'linux-vdso.so.1': No such file
dpkg-query: no path found matching pattern *linux-vdso.so.1*
Anyway, the whole point was to say that the upgrade failed when trying
to start the display manager and to suggest a cure. I don't think it
was anything I installed that caused this. Have you a better one?

wishing to upgrade and finding it doesn't work. My work-around was to
create a symbolic link (result as below) for the missing file based on
the pattern for symbolic links elsewhere: jessie now works OK.
