MobileRead Forums - Calibre does not recognise Kobo Libra H20

Hi All,

I bought a Kobo Libra H20 but am unable to get Calibre to recognize it. I have version 5.27 of Calibre installed.

I have gone through the FAQ (https://manual.calibre-ebook.com/faq...ted-by-calibre) and it was not able to help. I also tried other things (swapping cables, restarting computer, re running the wizard, ...) but am still not able to get it to work.

The device detect error that I got below. I looked through the forums and the closest post that I could find indicated that there was a bug in 4.22 (https://www.mobileread.com/forums/sh...d.php?t=340249) but that this was corrected in 4.22.1 (and at present I am on 5.27)

Could someone please help?

Thankyou
