Kobo libra 2 and calibre 3.48

Hoping someone can help. Is there a way to get calibre 3.48 to recognize and work with a kobo libra 2 ?

I'm running an older mac that which can only run OS 10.13.6 (Mac OS High Sierra) so the last version of Calibre is 3.48 and that version I understood doesn't have a driver for the kobo libra 2.

Is there a way to get this working, driver download and manual installation ?

Thanks
