Similar messages to those that have gone before: my last IOError message
Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 87, in run
File "site-packages\calibre\gui2\device.py", line 510, in _books
File "site-packages\calibre\devices\kobo\driver.py", line 1761, in books

IOError: IOError: disk I/O error

I've been in IT quite a while and normally figure out stuff like this but after spending hours and hours on this trying many permutations - I'm just having to grumpily give up and manage by transferring epub files using windows explorer - disappointed as in all other aspects I believe the Kobo Aura H2o Ed2 is a much better option for those who want the flexibility and capacity.

FYI I've got W10 on an HP Pavillion laptop - I have the latest Kobo firmware 4.7.10413 and Caliber 3.19.0. I've tried USB 2 and USB 3 ports, factory-resetting the Kobo, re-powering Kobo and laptop, with and without the Kobo extended Touch and utility plugins, I'm always seeing the same issue - once I've connected to Caliber after initialising everything and done something such as transferring ebooks ; the next connect I always get an IO error despite a reboot of laptop and Kobo - the first sync between Caliber and the Kobo cannot finish - it seems arbitrary. (FYI I've also tried using the device detection utility in Caliber and entered to USB parameters into the User defined USP port device plugin).

If you have any ideas I'd be REALLY HAPPY to hear from you thanks ....! My suspicion is that its a bug in Caliber or an HP USB driver issue- I'm more inclined to think it's a Caliber derived issue but at Wits end trying to solve this....!! If you read this many Thanks.....
