Calibre not finding my Kindle Fire HD
I've looked through the forum but couldn't find this problem addressed elsewhere, so forgive me if it is a duplicate.
I've plugged my Kindle Fire HD into my computer via USB, but Calibre isn't seeing it at all. Is there some setting in either Calibre or Kindle I need to change? It sounds like Calibre does support the Fire, so I'm not sure what the problem is.
Any help is MUCH appreciated!
