Calibre stopped recognising Kindle Touch

Hi there,

For some reason Calibre has stopped recognising my Kindle Touch. Just got it yesterday and it worked straight from the get go once I had enabled the Kindle Touch plugin. Then for some reason when I connect today it fails to see it at all even although it is coming up as a drive on my computer.

I have tried Kovid's solutions to no avail and turning the kindle plugin on and off and back on again.

Any help would be appreciated:

Here's my debug info:
