Calibre 5.0.0 does not detect my Kindle Paperwhite

[markvdvelde]

Hi,

I just upgraded to Calibre 5.0.0 and for the first time in 10 years Calibre fails to detect my Kindle (currently a Paperwhite, released in 2015).

I ran Calibre in debug-mode and the txt file says:

Unable to open device <calibre.devices.kindle.driver.KINDLE2 object at 0x11469a430>

During handling of the above exception, another exception occurred:

Device connect failed again, giving up

I restarted Calibre, my Kindle but so far nothing has worked...

Exactly the same story here with my Kindle Voyage... won't connect since updating Calibre this morning

Indeed, device detection is broken on macOS, it's caused by the change to python 3 will be fixed in the next release, which I will make in a day or two.

Great, thanks for all the work you put into it!

Same (5.0) problem with both my Kobo readers. But 5.0.1 fixed it. Speedy stuff. Thank you.

Better send more munny...
