You could try using this custom version of the KoboTouch plugin that might recognise your Libra Colour on Calibre 3.48:

If that doesn't work, your only option would be to manage your books without using Calibre. You can still copy books directly over USB, but you can't sync your Calibre library. Export all your books as either EPUB or KEPUB, and then copy/paste them over USB onto your Kobo's internal storage.

This is a significant downside to using Calibre for book management, since Kovid doesn't maintain support for older operating systems, and old Calibre versions can't talk to newer e-readers.
